I wrote the following to see if a submitted URL has a valid http response code and also if it responds quickly.
Use the code like this:
<?php
$is_ok = http_response($url); // returns true only if http response code < 400
?>
The second argument is optional, and it allows you to check for a specific response code
<?php
http_response($url,'400'); // returns true if http status is 400
?>
The third allows you to specify how long you are willing to wait for a response.
<?php
http_response($url,'200',3); // returns true if the response takes less than 3 seconds and the response code is 200
?>
<?php
function http_response($url, $status = null, $wait = 3)
{
$time = microtime(true);
$expire = $time + $wait;
// we fork the process so we don't have to wait for a timeout
$pid = pcntl_fork();
if ($pid == -1) {
die('could not fork');
} else if ($pid) {
// we are the parent
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, TRUE);
curl_setopt($ch, CURLOPT_NOBODY, TRUE); // remove body
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$head = curl_exec($ch);
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
if(!$head)
{
return FALSE;
}
if($status === null)
{
if($httpCode < 400)
{
return TRUE;
}
else
{
return FALSE;
}
}
elseif($status == $httpCode)
{
return TRUE;
}
return FALSE;
pcntl_wait($status); //Protect against Zombie children
} else {
// we are the child
while(microtime(true) < $expire)
{
sleep(0.5);
}
return FALSE;
}
}
?>
Hope this example helps. It is not 100% tested, so any feedback [sent directly to me by email] is appreciated.

WARNING WARNING
In this example: http://php.net/manual/en/book.curl.php#102885 by "frank at interactinet dot com"
There's a small bug in
<?php
...
elseif($status == $httpCode)
{
return TRUE;
}
return FALSE;
pcntl_wait($status); //Protect against Zombie children
} else {
// we are the child
while(microtime(true) < $expire)
...
?>
The code will immediately leave the function at the `return`, and pcntl_wait() will NEVER be executed, under any circumstances.
I can't see any other issues with this function however.

I needed to use cURL in a php script to download data using not only SSL for the server authentication but also for client authentication.
On a default install of Fedora, setting up the proper cURL parameters, I would get an error:
$ php curl.php
Peer certificate cannot be authenticated with known CA certificates
The data on http://curl.haxx.se/docs/sslcerts.html was most useful. Indeed, toward to bottom it tells you to add a missing link inside /etc/pki/nssdb to use the ca-bundle.crt file. You do it so:
# cd /etc/pki/nssdb
# ln -s /usr/lib64/libnssckbi.so libnssckbi.so
Now you can do client authentication, provided you have your certificate handy with:
<?php
$data = "<soap:Envelope>[...]</soap:Envelope>";
$tuCurl = curl_init();
curl_setopt($tuCurl, CURLOPT_URL, "https://example.com/path/for/soap/url/");
curl_setopt($tuCurl, CURLOPT_PORT , 443);
curl_setopt($tuCurl, CURLOPT_VERBOSE, 0);
curl_setopt($tuCurl, CURLOPT_HEADER, 0);
curl_setopt($tuCurl, CURLOPT_SSLVERSION, 3);
curl_setopt($tuCurl, CURLOPT_SSLCERT, getcwd() . "/client.pem");
curl_setopt($tuCurl, CURLOPT_SSLKEY, getcwd() . "/keyout.pem");
curl_setopt($tuCurl, CURLOPT_CAINFO, getcwd() . "/ca.pem");
curl_setopt($tuCurl, CURLOPT_POST, 1);
curl_setopt($tuCurl, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($tuCurl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($tuCurl, CURLOPT_POSTFIELDS, $data);
curl_setopt($tuCurl, CURLOPT_HTTPHEADER, array("Content-Type: text/xml","SOAPAction: \"/soap/action/query\"", "Content-length: ".strlen($data)));
$tuData = curl_exec($tuCurl);
if(!curl_errno($tuCurl)){
$info = curl_getinfo($tuCurl);
echo 'Took ' . $info['total_time'] . ' seconds to send a request to ' . $info['url'];
} else {
echo 'Curl error: ' . curl_error($tuCurl);
}
curl_close($tuCurl);
echo $tuData;

CURL failed with PHP5.3 and Apache2.2.X on my Windows 7 machine.
It turns out that it's not enough to copy the two dll's mentioned (libeay32 and sslea32) from the php folder into your system32 folder. You HAVE TO UNBLOCK THESE TWO FILES.
Right click the file, select unblock, for each one. Then restart Apache.
Another very handy security feature added into Windows.

Here you have a function that I use to get the content of a URL using cURL:
function getUrlContent($url){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt($ch, CURLOPT_TIMEOUT, 5);
$data = curl_exec($ch);
$httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
return ($httpcode>=200 && $httpcode<300) ? $data : false;
}

After a lot of frustration with the fact that nobody has documented which curl commandline options go with which library functions, I discovered that the curl commandline will tell you (in the form of a C program) if you add `--libcurl foo.c`
If you've been struggling with trying to figure out how to get your fancy curl commandline to work in PHP, this makes it a breeze!

In order to use curl with secure sites you will need a ca-bundle.crt file; here's a PHP script I've written which creates a fresh ca-bundle:
http://www.gknw.net/php/phpscripts/mk-ca-bundle.php
I've also written scripts in other languages, f.e. the Perl one which ships now with curl distributions:
http://curl.haxx.se/lxr/source/lib/mk-ca-bundle.pl
and also a Win32 WSH script if you prefer that:
http://www.gknw.net/vb/scripts/mk-ca-bundle.vbs

This anomali only happen on windows.
Server indicates that some variables built by http_build_query() is missing.
<?php
//...
//...
//...
$ping_url = $this->sx_url.'ping.php?'.http_build_query($options);
$message = $this->_post_curl($ping_url);
?>
After debugging i found that $ping_url contain url like :
http://example.com/ping.php?app=1&key=mail&ttd=df52861e
But myserver give "No ttd GET variable" response
This problem fixed by adding optional parameter to make sure that http_build_query() use only '&' as arg separator rather than '&'
<?php
//...
//...
//...
$ping_url = $this->sx_url.'ping.php?'.http_build_query($options,'','&');
$message = $this->_post_curl($ping_url);

A solution that addresses repeat calls to the same set of urls using the same connection simulating frequent ajax calls in separate browser tabs.
In a unique situation you may need to set a cookie then use that cookie for multiple separate persistent connections using the same session cookie. The problem is the session cookie may change while your doing your persistent calls. If you set every curl handle to update a shared cookiejar on close you may overwrite the new found session value with the old session value depending on the closing order of your handles. Also, because the cookiejar is only written to on a curl_close, you may be using dissimilar or old session info in some of your 'faked browser tabs'.
To solve this problem I created a unique handle that opens and closes specifically to set a cookie file using CURLOPT_COOKIEJAR. Then I just use the read-only CURLOPT_COOKIEFILE on the multiple separate persistent handles.
This solves the problem of shared cookies fighting to write their values and keep persistent calls using the most up to date cookie information.
Note: In my case the multiple calls were in a while loop and I was using php in shell. The session cookie value plus browser type limited the number of connections available and i wanted to use the max connections per session.

If you need to send an array of files using CURL (typical case: POST variable to a REST API), having an array of CURLFiles in the POSTFIELD won't work. You have to set as many variables in your postfield than there are files to send:
<?php
// Won't work:
$postfields = array(
'files' => array(
new CURLFile($path1),
new CURLFile($path2),
//...
)
);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields);
// Use this instead:
$postfields = array(
'files[0]' => new CURLFile($path1),
'files[1]' => new CURLFile($path2),

I wanted to create a script that acted as a bridge between an external server and an internal server, wherein the internal server was not connected to the internet, but had information required by the users connecting to the external server. I hatched the idea to use curl to connect from the external server to the internal server (using request variables to send queries) and return everything (data and headers) returned by the file server.
After being driven mad by segmentation faults and crashes because the curl_exec didn't like me having the CURLOPT_HEADERFUNCTION's function directly dumping the header:
<?php
function Duplicate_Header($curl, $header)
{
header($header);
return strlen($header);
}
?>
... I tried (on a whim) duplicating and trimming the header and passing the duplicate to the header function...
<?php
function Duplicate_Header($curl, $header)
{
$duplicate = trim($header);
header($duplicate);
return strlen($header);
}
?>
Which worked just fine. I don't know if this is just some quirk of PHP4 or my lack of understanding of how the curl and header function works.

I'm having problem to read this website.
https://jornalggn.com.br/noticia/moro-agora-levanta-sigilo-de-decisao-que-protege-delatores-de-orgaos-federais-0
Because of redirects and browser checking.
Any links from this https://jornalggn.com.br/
I'm receiving just this response:
"Checking your browser before accessing jornalggn.com.br.
This process is automatic. Your browser will redirect to your requested content shortly.
Please allow up to 5 seconds…"
Any tips, how to solve this using php_curl
Thanks in advance

curl does not seem to work with SSL TLS (FTPES)
It will throw the following error:
(1) Protocol ftpes not supported or disabled in libcurl
