It took me longer than a week to figure out how to implement WSSE (Web Service Security) headers in native PHP SOAP. There are no much resource available on this, so thought to add this here for community benefit.
Step1: Create two classes to create a structure for WSSE headers
<?php
class clsWSSEAuth {
private $Username;
private $Password;
function __construct($username, $password) {
$this->Username=$username;
$this->Password=$password;
}
}
class clsWSSEToken {
private $UsernameToken;
function __construct ($innerVal){
$this->UsernameToken = $innerVal;
}
}
?>
Step2: Create Soap Variables for UserName and Password
<?php
$username = 1111;
$password = 1111;
//Check with your provider which security name-space they are using.
$strWSSENS = "http://schemas.xmlsoap.org/ws/2002/07/secext";
$objSoapVarUser = new SoapVar($username, XSD_STRING, NULL, $strWSSENS, NULL, $strWSSENS);
$objSoapVarPass = new SoapVar($password, XSD_STRING, NULL, $strWSSENS, NULL, $strWSSENS);
?>
Step3: Create Object for Auth Class and pass in soap var
<?php
$objWSSEAuth = new clsWSSEAuth($objSoapVarUser, $objSoapVarPass);
?>
Step4: Create SoapVar out of object of Auth class
<?php
$objSoapVarWSSEAuth = new SoapVar($objWSSEAuth, SOAP_ENC_OBJECT, NULL, $strWSSENS, 'UsernameToken', $strWSSENS);
?>
Step5: Create object for Token Class
<?php
$objWSSEToken = new clsWSSEToken($objSoapVarWSSEAuth);
?>
Step6: Create SoapVar out of object of Token class
<?php
$objSoapVarWSSEToken = new SoapVar($objWSSEToken, SOAP_ENC_OBJECT, NULL, $strWSSENS, 'UsernameToken', $strWSSENS);
?>
Step7: Create SoapVar for 'Security' node
<?php
$objSoapVarHeaderVal=new SoapVar($objSoapVarWSSEToken, SOAP_ENC_OBJECT, NULL, $strWSSENS, 'Security', $strWSSENS);
?>
Step8: Create header object out of security soapvar
<?php
$objSoapVarWSSEHeader = new SoapHeader($strWSSENS, 'Security', $objSoapVarHeaderVal,true, 'http://abce.com');
//Third parameter here makes 'mustUnderstand=1
//Forth parameter generates 'actor="http://abce.com"'
?>
Step9: Create object of Soap Client
<?php
$objClient = new SoapClient($WSDL, $arrOptions);
?>
Step10: Set headers for soapclient object
<?php
$objClient->__setSoapHeaders(array($objSoapVarWSSEHeader));
?>
Step 11: Final call to method
<?php
$objResponse = $objClient->__soapCall($strMethod, $requestPayloadString);
?>
SoapClient::SoapClient
(PHP 5, PHP 7)
SoapClient::SoapClient — SoapClient constructor
Descrierea
This constructor creates SoapClient objects
in WSDL or non-WSDL mode.
Parametri
-
wsdl -
URI of the
WSDLfile ornullif working innon-WSDLmode.Notă:
During development, WSDL caching may be disabled by the use of the
soap.wsdl_cache_ttlphp.ini setting otherwise changes made to the WSDL file will have no effect untilsoap.wsdl_cache_ttlis expired. -
options -
An array of options. If working in WSDL mode, this parameter is optional. If working in non-WSDL mode, the
locationandurioptions must be set, wherelocationis the URL of the SOAP server to send the request to, anduriis the target namespace of the SOAP service.The
styleanduseoptions only work in non-WSDL mode. In WSDL mode, they come from the WSDL file.The
soap_versionoption should be one of eitherSOAP_1_1orSOAP_1_2to select SOAP 1.1 or 1.2, respectively. If omitted, 1.1 is used.For HTTP authentication, the
loginandpasswordoptions can be used to supply credentials. For making an HTTP connection through a proxy server, the optionsproxy_host,proxy_port,proxy_loginandproxy_passwordare also available. For HTTPS client certificate authentication uselocal_certandpassphraseoptions. An authentication may be supplied in theauthenticationoption. The authentication method may be eitherSOAP_AUTHENTICATION_BASIC(default) orSOAP_AUTHENTICATION_DIGEST.The
compressionoption allows to use compression of HTTP SOAP requests and responses.The
encodingoption defines internal character encoding. This option does not change the encoding of SOAP requests (it is always utf-8), but converts strings into it.The
traceoption enables tracing of request so faults can be backtraced. This defaults tofalseThe
classmapoption can be used to map some WSDL types to PHP classes. This option must be an array with WSDL types as keys and names of PHP classes as values.Setting the boolean
traceoption enables use of the methods SoapClient->__getLastRequest, SoapClient->__getLastRequestHeaders, SoapClient->__getLastResponse and SoapClient->__getLastResponseHeaders.The
exceptionsoption is a boolean value defining whether soap errors throw exceptions of type SoapFault.The
connection_timeoutoption defines a timeout in seconds for the connection to the SOAP service. This option does not define a timeout for services with slow responses. To limit the time to wait for calls to finish the default_socket_timeout setting is available.The
typemapoption is an array of type mappings. Type mapping is an array with keystype_name,type_ns(namespace URI),from_xml(callback accepting one string parameter) andto_xml(callback accepting one object parameter).The
cache_wsdloption is one ofWSDL_CACHE_NONE,WSDL_CACHE_DISK,WSDL_CACHE_MEMORYorWSDL_CACHE_BOTH.The
user_agentoption specifies string to use inUser-Agentheader.The
stream_contextoption is a resource for context.The
featuresoption is a bitmask ofSOAP_SINGLE_ELEMENT_ARRAYS,SOAP_USE_XSI_ARRAY_TYPE,SOAP_WAIT_ONE_WAY_CALLS.The
keep_aliveoption is a boolean value defining whether to send theConnection: Keep-Aliveheader orConnection: close.The
ssl_methodoption is one ofSOAP_SSL_METHOD_TLS,SOAP_SSL_METHOD_SSLv2,SOAP_SSL_METHOD_SSLv3orSOAP_SSL_METHOD_SSLv23.
Erori/Excepții
SoapClient::SoapClient() will generate an
E_ERROR error if the location and
uri options aren't provided in non-WSDL mode.
A SoapFault exception will be thrown if the
wsdl URI cannot be loaded.
Exemple
Example #1 SoapClient::SoapClient() example
<?php
$client = new SoapClient("some.wsdl");
$client = new SoapClient("some.wsdl", array('soap_version' => SOAP_1_2));

Do note that *contrary* to the ssl context option (http://php.net/manual/en/context.ssl.php#context.ssl.local-pk), `local_pk` is NOT a valid option. For the `local_cert` option, you should combine the private key with the certificate file.
Alternatively, if you do want to keep the private key and certificate file separate, you can create a stream context and pass that as the `context` option:
<?php
$context = stream_context_create([
'ssl' => [
'local_cert' => '/path/to/cert/file',
'local_pk' => '/path/to/private/key'
]]);
$client = new \SoapClient($wsdl, [
'context' => $context,
// other options
]);

As noted in the bug report http://bugs.php.net/bug.php?id=36226, it is considered a feature that sequences with a single element do not come out as arrays. To override this "feature" you can do the following:
$x = new SoapClient($wsdl, array('features' =>
SOAP_SINGLE_ELEMENT_ARRAYS));

The documentation is wrong (version 7.1.12): A SoapFault exception will be thrown if the wsdl URI cannot be loaded.
What actually occurs -- even if wrapped in a try...catch(\Throwable $t) -- is an UNCATCHABLE fatal error is thrown.

CAUTION:
I had quite a bit of trouble trying to make a request with fopen through a proxy to a secure url. I kept getting a 400 Bad Request back from the remote host. It was receiving the proxy url as the SNI host. In order to get around this I had to explicity set the SNI host to the domain I was trying to reach. It's apparently the issue outlined in this bug:
https://bugs.php.net/bug.php?id=63519
<?php
$domain = parse_url($file, PHP_URL_HOST);
$proxy_string = "tcp://" . WP_PROXY_HOST . ":" . WP_PROXY_PORT;
$opts = array(
'http' => array( 'proxy' => $proxy_string ),
'ssl' => array( 'SNI_enabled' => true, 'SNI_server_name' => $domain));
$context = stream_context_create($opts);
$handle = fopen( $file, 'r', false, $context );
?>

This doesn't seem to be documented, but when you want to use compression for your outgoing requests, you have to OR with the compression level:
<?php
$client = new SoapClient("some.wsdl",
array('compression' => SOAP_COMPRESSION_ACCEPT | SOAP_COMPRESSION_GZIP | 9));
?>
This can be really usefull if you want to send large amounts of data.

Note that creating a soap client for an invalid URL (you do test what happens, when a service is not available, right?) usually throws an exception which can be caught with try..catch. However, if xdebug is active you will get a fatal error, which obviously cannot be caught.

Hello folks!
A hint for developers:
When programming some soap server set the "soap.wsdl_cache_enabled" directive in php.ini file to 0:
soap.wsdl_cache_enabled=0
Otherwise it will give a bunch of strange errors saying that your wsdl is incorrect or is missing.
Doing that will save you from a lot of useless pain.

In local_cert, the order of the certificates is relevant. After the key, first add the client certificate, then the rest of the chain. Offering the certificate chain before the client cert or only adding it to the system capath will result in an "alert unknown ca".

if you need to use ws-security with a nonce and a timestamp, you can use this :
<?php
class WsseAuthHeader extends SoapHeader {
private $wss_ns = 'http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd';
private $wsu_ns = 'http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd';
function __construct($user, $pass) {
$created = gmdate('Y-m-d\TH:i:s\Z');
$nonce = mt_rand();
$passdigest = base64_encode( pack('H*', sha1( pack('H*', $nonce) . pack('a*',$created). pack('a*',$pass))));
$auth = new stdClass();
$auth->Username = new SoapVar($user, XSD_STRING, NULL, $this->wss_ns, NULL, $this->wss_ns);
$auth->Password = new SoapVar($pass, XSD_STRING, NULL, $this->wss_ns, NULL, $this->wss_ns);
$auth->Nonce = new SoapVar($passdigest, XSD_STRING, NULL, $this->wss_ns, NULL, $this->wss_ns);
$auth->Created = new SoapVar($created, XSD_STRING, NULL, $this->wss_ns, NULL, $this->wsu_ns);
$username_token = new stdClass();
$username_token->UsernameToken = new SoapVar($auth, SOAP_ENC_OBJECT, NULL, $this->wss_ns, 'UsernameToken', $this->wss_ns);
$security_sv = new SoapVar(
new SoapVar($username_token, SOAP_ENC_OBJECT, NULL, $this->wss_ns, 'UsernameToken', $this->wss_ns),
SOAP_ENC_OBJECT, NULL, $this->wss_ns, 'Security', $this->wss_ns);
parent::__construct($this->wss_ns, 'Security', $security_sv, true);
}
}
?>
and with your SoapClient do :
<?php
$client = new SoapClient("http://host/path");
$client->__setSoapHeaders(Array(new WsseAuthHeader("user", "pass")));
?>
works for me. based on a stackoverlfow post which only did the username and password, not the nonce and the timestamp

Example for a soap client with HTTP authentication over a proxy:
<?php
new SoapClient(
'service.wsdl',
array(
// Stuff for development.
'trace' => 1,
'exceptions' => true,
'cache_wsdl' => WSDL_CACHE_NONE,
'features' => SOAP_SINGLE_ELEMENT_ARRAYS,
// Auth credentials for the SOAP request.
'login' => 'username',
'password' => 'password',
// Proxy url.
'proxy_host' => 'example.com', // Do not add the schema here (http or https). It won't work.
'proxy_port' => 44300,
// Auth credentials for the proxy.
'proxy_login' => NULL,
'proxy_password' => NULL,
)
);
?>
Providing an URL to a WSDL file on the remote server (which as well is protected with HTTP authentication) didn't work. I downloaded the WSDL and stored it on the local server.

If your WSDL file containts a parameter with a base64Binary type, you should not use base64_encode() when passing along your soap vars. When doing the request, the SOAP library automatically base64 encodes your data, so otherwise you'll be encoding it twice.
WSDL snipplet:
<element name="content" type="base64Binary" xmime:expectedContentTypes="*/*"/>
<?php
$string = 'data_you_want_to_send___like_xml_in_soap';
$soap_data = array(
'foo' => 'bar',
//'content' => base64_encode($string ) // don't do this
'content' => $string //do this
);
$response = $client->Send($soap_data);

It should be noted that if you receive a return error : 'Object reference not set to an instance of an object.'. This could be due to something as simple as passing the incorrect parameters. When you look at this XML:
<Get xmlns="http://example.com">
<request>
<CustomerId>string</CustomerId>
<From>dateTime</From>
<To>dateTime</To>
</request>
</Get>
Your code should look something like this:
<?php
try {
$options = array(
'soap_version'=>SOAP_1_2,
'exceptions'=>true,
'trace'=>1,
'cache_wsdl'=>WSDL_CACHE_NONE
);
$client = new SoapClient('http://example.com/doc.asmx?WSDL', $options);
// Note where 'Get' and 'request' tags are in the XML
$results = $client->Get(array('request'=>array('CustomerId'=>'1234')));
} catch (Exception $e) {
echo "<h2>Exception Error!</h2>";
echo $e->getMessage();
}
$results = $client->Get(array('request'=>array('CustomerId'=>'842115')));

When using classmap option to map the SOAP results to a class, the constructor
of the object you've mapped to is not called.
$client = new SoapClient("url_to_wsdl",
array('classmap' => array('contact' => "Contact"));
$params = array("1");
$contact = $client->__soapCall("get_contact", $params);
Expected result:
A contact object that has properties initialized (i.e. db connections,
....).
Actual result:
A contact object without the properties.
Thanks for your help.

The same goes for using an SSL client certficate, the SoapClient will only present the certificate on the actual remote call, not when getting the WSDL. The workaround is the same as above. HttpRequest works as expected.

If you want to use classes in a different namespace in your classmap, just use the backslash in the the target class name.
Example:
<?php
$classmap = array('result' => 'MyNamespace\\Result');
?>
You need to specify the backslash twice because it is the escape character in strings.

I found a good use for typemap. When using classmap any xml tags that had attributes, attribute values were not captured, so a typemap allows you to override how a class gets implemented and being able to get any attributes not previously captured.
<ItemList>
<Item productId="1234">
<feature>red</feature>
</Item>
<Item productId="5678">
<feature>blue</feature>
</Item>
</ItemList>
<?php //semi-pseudo code
namespace ExampleNS;
class ItemList {
public $item = [];
}
class Item {
public $productId;
public $feature;
}
class Service {
public function __construct(){
$options = [
'classmap' => [
'ItemList' => 'ExampleNS\ItemList',
'Item' => 'ExampleNS\Item'
],
'typemap'=>[
'type_ns' => 'http://some.wsdl.ns/sdo',
'type_name' => 'Item',
'from_xml' => [__CLASS__,'newConversion']
]
];
}
public function newConversion($xml){

If you're using CLI and there are multiple IP addresses available for outgoing SOAP-requests, try this "secret" to set outgoing IP:
e.g. for local IP 10.1.4.71:
$opts = array('socket' => array('bindto' => '10.1.4.71:0'));
$context = stream_context_create($opts);
$client = new SoapClient(null, array('location'=>'http://...','uri' => '...','stream_context' => $context));
You can also set other options for the stream context, please refer to this page:

As of version 5.0.4 you can now dynamically change your location even if you're using a wsdl
<?php
$client = new SoapClient("http://some.host.net/wsdl/somefile.wsdl",array(
"location" => 'myurl.com'));
?>
notice you can now use the "location" key.
This means you can have the same wsdl file not define a location until runtime which is great if you have a development test site or if you distribute your files to other companies.
Prior to this change you would have to ship a custom wsdl file to every client you had with their location hardcoded.

Being new to SOAP, I was searching for a while to find out why my message was getting a response in soapUI, but not with my php code. The specific service I was addressing gives a HTTP 202 Accepted on success (no response), but returns a SOAP message on errors.
Situation:
Using an (authenticated) client connection, and a WDSL file, SOAP calls with type "One-Way" don't give a response header, even though a response is expected.
Solution:
When calling the client constructor, set SOAP_WAIT_ONE_WAY_CALLS in the $options['features'].

Where you have the problem of
"looks like we got no XML document SoapClient", really the real problem is the xml code from remote server is not clear (after last tag is possible that you have space or other caracter that the your supplier of service have lost : no one is perfect!)
I've read some solution, like here, but you must to know that is possible, that is possible that the remote server don't wrong, and the "surplus" (latin word for added values) is needed.
In particolar with axis Java server, is possible that the configuration of server is needed and the "surplus" is one or more attachments...
The solution is 3:
1) contact your supplier if is possible to remove caracter if is an error (good luck! ;) )
2) use another class like nusoap resolve the problem (but has other problem!)
3) this technical solution:
when call the wsdl be sure that the option trace and exceptions are setted (the first true and the second false)
<?php
$SoapClient = new SoapClient(NULL,
array(
....
'trace' => 1,
'exceptions' => 0
)
?>
(if you don't do that you can't use the __getLastResponse)
Now You can do the request and use __getLastResponse() to obtain all the part..
<?php
$result = $SoapClient -> problematicCall($par);
?>
After all you obtain a variable like that:
-----=_Part_9325_126764118.1363377774664
Content-Type: text/xml; charset=UTF-8
Content-Transfer-Encoding: binary

-------------------------
Is easy understand if the added part is needed or not!
Now you can explode all the part and parse!
Hope this can help you.See ya in the cyberspace!

Note that if libxml_disable_entity_loader() has been called, you cannot specify a WSDL file - you'll get an error that PHP "failed to load external entity".
To resolve this, add
<?php
libxml_disable_entity_loader(false);
?>
Above any calls to instantiate SoapClient.
Arjan van Bentem ¶

When using HTTP basic authentication, PHP will only send the credentials when invoking the service, not when fetching the WSDL.
To solve this, one needs to fetch the WSDL manually (or using PHP, of course!) and store it on the file system. Obviously, the first parameter for SoapClient(..) then needs to refer to that local copy.
Alternatively, the user annotations at http://nl3.php.net/manual/en/ref.soap.php state that one could encode the login and password into the URL as well.
See http://bugs.php.net/bug.php?id=27777
psy at psyberware dot com ¶

If you try to use a 'stream_context' option to set additional HTTP headers, you should be aware of a couple of things.
First, even if you are using a https URL, the 'header' will be pulled from the 'http' section:
$context = stream_context_create([
'https' => [
'header' => 'Test: this will be ignored'
],
'http' => [
'header' => 'Test: this will be used'
]
]);
Second, there are a number of headers that are ignored, and will never be used. Check the underlying C source file soap/php_http.c and search for "skip some predefined headers" for a list. This is the reason some people report problems trying to set Host, Authorization, and other headers in certain situations.

I was struggling to with a vendor's API that required a specific Content-Type in the HTTP header. Looking over the PHP source code, I found an undocumented feature that allows for this.
<?php
// Add a custom header and override PHP's default Content-Type.
$stream_context = [
'http' => [
'header' => 'authType: 2WAYSSL',
'content_type' => 'text/xml;charset=utf-8',
]
];
$client = new SoapClient("some.wsdl", ['stream_context' => stream_context_create($stream_context)]);
?>

Note that the option "keep_alive" seems to be TRUE by default!
If you are having issues, for example getting the error:
"failed to open stream: Too many open files in"
When executing a multitude of soap requests using a new SoapClient per request will quickly lead to this error.
What to do:
Add the option 'keep_alive' and set it to false!
<?php
$client = new SoapClient('/path/to/some.wsdl', ['keep_alive' => false,]);
?>
What NOT to do:
Increasing the amount of file streams that are allowed per process. This is just a work-around for an issue that can easily solved, which will still keep the actual problem alive - the soap client connections stay alive!

When using classmap, the class constructors are NOT called.
If you want to do additional "magic", you can use the __set() / __get() combo.
Register a class with a "container" property alone and use the 2 magic methods.
Have fun

Further explanation regarding the cache options in WSDL mode:
WSDL_CACHE_MEMORY:
Will do a request and cache the WSDL's xml when instantiating the SoapClient object for the first time; invoked by EVERY request.
WSDL_CACHE_DISK:
Will do a request and cache the WSDL's xml the first time the SoapClient object is instantiated by A request.

PHP 5.2.11 seems to not be very picky about the correctness of a WSDL.
Other SOAP clients were complaining about schema and namespace issues, while PHP's SoapClient worked completely fine. Fixing those issues for the other clients however broke PHP's SoapClient to the point where objects being passed to the SOAP method were becoming empty arrays on the server side.
Lesson learned: some elements were being prefixed with xsd: and others were not -- make absolutely sure your WSDL is correct and consistent (I'm using a tweaked WSDL_Gen.php).

I was having troubles getting responses from a Coldfusion SOAP server, with no obvious issues in the SoapClient used.
Eventually I found that the server was only accepting SOAP 1.1 requests and not 1.2. Not sure if this is a system wide Coldfusion setting but if you hit the same wall, try setting the SoapClient option "soap_version" to the constant SOAP_1_1 (which is the default but mine was defaulting to 1.2 as the client was being reused for another service)

There seems to be a problem with specifying empty strings for proxy_host and proxy_port options in recent versions of PHP (from a version later than 5.2.9, and equal to or earlier than 5.2.11).
Supplying empty string values for proxy_host and proxy_port causes "host not found" type errors: supplying NULL or FALSE works fine.

To those fighting with NTLM authenticated proxy servers, here's a solution I'm using atm:
<?php
/**
* A child of SoapClient with support for ntlm proxy authentication
*
* @author Meltir <meltir@meltir.com>
*
*/
class NTLM_SoapClient extends SoapClient {
public function __construct($wsdl, $options = array()) {
if (empty($options['proxy_login']) || empty($options['proxy_password'])) throw new Exception('Login and password required for NTLM authentication!');
$this->proxy_login = $options['proxy_login'];
$this->proxy_password = $options['proxy_password'];
$this->proxy_host = (empty($options['proxy_host']) ? 'localhost' : $options['proxy_host']);
$this->proxy_port = (empty($options['proxy_port']) ? 8080 : $options['proxy_port']);
parent::__construct($wsdl, $options);
}
/**
* Call a url using curl with ntlm auth
*
* @param string $url
* @param string $data
* @return string
* @throws SoapFault on curl connection error
*/
protected function callCurl($url, $data) {
$handle = curl_init();
curl_setopt($handle, CURLOPT_HEADER, false);
curl_setopt($handle, CURLOPT_URL, $url);
curl_setopt($handle, CURLOPT_FAILONERROR, true);
curl_setopt($handle, CURLOPT_HTTPHEADER, Array("PHP SOAP-NTLM Client") );
curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);
curl_setopt($handle, CURLOPT_POSTFIELDS, $data);
curl_setopt($handle, CURLOPT_PROXYUSERPWD,$this->proxy_login.':'.$this->proxy_password);
curl_setopt($handle, CURLOPT_PROXY, $this->proxy_host.':'.$this->proxy_port);
curl_setopt($handle, CURLOPT_PROXYAUTH, CURLAUTH_NTLM);
$response = curl_exec($handle);
if (empty($response)) {
throw new SoapFault('CURL error: '.curl_error($handle),curl_errno($handle));
}
curl_close($handle);
return $response;
}
public function __doRequest($request,$location,$action,$version,$one_way = 0) {
return $this->callCurl($location,$request);
}
}
?>
Requires curl and could be extended, but it works for my simple needs.

Though pointed out by jan at bestbytes, and discussed in bug #27777, one common source of the "Parsing WSDL: Couldn't find <definitions>" error is from trying to access a WSDL that is protected by HTTP authentication. Passing the login/password in the 2nd parameter doesn't always work; so if you encounter this error message and are trying to access a protected WSDL file, try passing the username and password in with the first parameter.

I had to struggle with a rather strange behavior when trying to consume standard Parlay X web services with no success. However, I found a remedy to my problem.
The problem which I faced was about an erroneous invalid HTTP basic authentication request sent to the web service. Although I was sending the right credentials, I was getting an authentication error. It turns out that PHP was sending HTTP requests to another endpoint which is not exposed directly through the web service and that end point does not require authentication.
My remedy for that issue was by using this simple lines in the example of using sendSms Paraly-X method.
First, creating a soap client without any HTTP authentication options:
<?php
$client = new SoapClient($wsdl_url);
?>
The above request will cache the wsdl in the /tmp directory. Immediately after this construction we create another soap client, this time with HTTP authentication options:
<?php
try {
$client = new SoapClient($wsdl_url, array('login' => "griffin",
'password' => "password"));
} catch (Exception $e) {
printf("Error:sendSms: %s\n",$e->__toString());
return false;
}
?>
Now it should work without any problem. Without the second call, PHP will call sendSms without credentials resulting in a failed attempt due to missing authentication information. I found this procedure to be the simplest.
This process should be done every time the cached wsdl expires, or simply a one can increase the time-to-live for the cached wsdl from php.ini

I had an issue figuring out the use of classmap that took me quite a while to figure out. I was assuming the WSDL type the docs were referring to was the name of the element being returned in the SOAP, so like,
<ns1:node id="8675309" />
and I was wondering why mapping
'classmap'=>array('node'=>'MyNode')
did nothing.
That's because in my WSDL I defined node as:
<xsd:element name="node" type="tns:nodeType" />
The classmap I needed was:
'classmap'=>array('nodeType'=>'MyNode')
I was able to find the type names using SoapClient->__getTypes()
Later, I realized where I could look inside the WSDL for the typename I needed.
I dunno if I missed something painfully obvious but maybe this can clear up some of the docs.

We've had some problems using SoapClient connecting to an external server via Microsoft ISA (presently v.2006 but this may apply to other versions too). We supply the proxy_host, proxy_port, proxy_login and proxy_password but the ISA server reports the login in its logs as "anonymous".
Our sysadmin believes this is because PHP is not supplying NTLN information (Windows security protocol) in the correct format (and whether it should work with proprietary proxies is of course another debate). We'd tried "username", "DOMAIN\username" to no effect. The solution is to add an exception in the ISA server for the target hostname/IP; null can then be supplied for proxy_login and proxy_password and the connection should then work as expected.
On a slightly related note, if you are having problems make sure the port number is supplied as an integer. Some versions of PHP will not use the proxy with SoapClient if the port number is supplied as a string.

For anyone having trouble with ArrayOf_xsd_string and getting an error similar to 'No deserializer defined for array type {http://www.w3.org/2001/XMLSchema}string'
Try using the 'features' param, set to SOAP_USE_XSI_ARRAY_TYPE - this makes sure the correct deserializer is used.
eg,
<?php
$client = new SoapClient("some.wsdl", array('features' => SOAP_USE_XSI_ARRAY_TYPE));
?>

i was looking for a good example and couldnt find one,
finally found it somewhere(forgot where) i think this is
the best example to make a soap request with multiple params
$params->AWSAccessKeyId = AMAZON_API_KEY;
$params->Request->SearchIndex = 'Books';
$params->Request->Keywords = 'php5 oop';
$amazon = new SoapClient('http://webservices.amazon.com
/AWSECommerceService/AWSECommerceService.wsdl');
$result = $amazon->itemSearch($params);

When using classmap to map the SOAP results to a class, the constructor of the object you've mapped to is _not_ called. This applies to the PHP5 __construct() and the PHP4 ClassName() constructors.

I kept having a problem using an HTTP proxy with SOAP. The proxy_port parameter has to be an integer, ie. "proxy_port"=>"80" won't work, you'll have to use "proxy_port"=>80.
HTH,

If you connect to a SoapServer, that has been created with session persistence, you can access the server's session id via SoapClient->_cookies[<session_id_name>][0]. This property becomes available after your first client method call.
I have only tested this with session.use_cookies=1.

Using a WSDL file is the way to go, however, for my particular application, the LOCATION:PORT needed to be dynamic so that my SOAP clients would be able to call a different service based on the client domain.
If you are using a WSDL, SoapClient() requires a URL direct to an actual URL and does not let you use a PHP file that outputs the dynamic WSDL XML in its stead. So, I ended up making a separate WSDL for each possible service needed and had to maintain them all if the service description changed.
Finally, after some fiddling, I was able to create a PHP page with the proper Mime type headers so that I could then trick SoapClient() to think that it was being passed a file with a ".wsdl" extension.
Example:
<?php
// filename: wsdl.php
header('Content-Type: application/xml; charset=UTF-8');
header('Content-Disposition: attachment; filename="filename.wsdl"');
$wsdl = 'path/wsdl_name.wsdl';
// read in file
$handle = fopen($wsdl, "r");
$wsdl_xml = fread($handle, filesize($wsdl));
fclose($handle);
// put code here to replace url and port in xml
echo $wsdl_xml;
?>
Now, in order to make this work, you can't just call a relative path to the file. I believe it has to go through Apache to properly set the mime type headers, etc... So you would use a full "http://....." address as the path to the wsdl.php file.
<?php
//... somewhere in your soap client code
$wsdl_loc = "http://yourdomain.com/wsdl.php";
$soap_client = new SoapClient($wsdl_loc, $client_param_array);
?>
Another, perhaps not so clean, way of achieving this would be to modify your .htaccess file in the directory where your WSDL file exists to force ".wsdl" files to run through the PHP engine. Add the following to your .htaccess:
AddType application/x-httpd-php .php .wsdl
You can then put dynamic PHP code snippets in your *.wsdl files to change whatever values you need to.
There are pros and cons to each solutions. The Mime solution probably taxes the system more as it has to read the file in every time a soap request is made. The htaccess solution makes it so you have to depend on either a modified .htaccess or Apache conf file.
Perhaps if you set the "soap.wsdl_cache_enabled", using ini_set(), to 1 (default), the caching will make it so it doesn't read the file every time for the Mime solution.
