    SoapServer::addFunction

    (PHP 5, PHP 7, PHP 8)

    SoapServer::addFunction — 添加一个或多个函数来处理 SOAP 请求

    说明

    public SoapServer::addFunction(array|string|int $functions): void

    为远程客户端导出一个或多个函数

    参数

    functions

    导出一个函数，将函数名作为字符串传递给这个参数。

    导出多个函数，将一组函数名作为数组传递。

    导出所有函数，传递特殊常量 SOAP_FUNCTIONS_ALL.

    注意:

    functions 接收的所有输入参数必须同时和 WSDL 文件中定义的顺序一样（它们不应该接收任何输出变量作为参数）并且返回一个或多个值。如果要返回多个值，它们必须返回一组被命名的输出参数作为数组。

    返回值

    没有返回值。

    示例

    示例 #1 SoapServer::addFunction() 示例

    <?php

    function echoString($inputString)
    {
    return     $inputString;
    }

    $server->addFunction("echoString");

    function     echoTwoStrings($inputString1, $inputString2)
    {
    return array(    "outputString1" => $inputString1,
    "outputString2" => $inputString2);
    }
    $server->addFunction(array("echoString", "echoTwoStrings"));

    $server->addFunction(SOAP_FUNCTIONS_ALL);

    ?>

    Be careful with SOAP_FUNCTIONS_ALL, as it adds ALL availiable PHP functions to your server.

    This can be a potential security threat, imagine clients doing this:

    echo $client->file_get_contents("c:\\my files\\my_passwords.doc");

    And voila, they have the contents of your file my_passwords.doc.

    In response to comment by Nathan O'Sullivan about returning (or passing) a complex type, you can also use the stdClass() object.

    Assume you define a complex type like so:

    <xsd:complexType name="TestType">
            <xsd:all>
                    <xsd:element name="A" type="xsd:string" />
                    <xsd:element name="B" type="xsd:int" />
                    <xsd:element name="C" type="xsd:boolean" />
            </xsd:all>
    </xsd:complexType>

    To use an object in place of an array you can do:

    $test = new stdClass();
    $test->A = "test string";
    $test->B = 45;
    $test->C = false;

    $result = $client->Test($test);

    You may be left wondering, as I was, how to return a complex type - consider the following WSDL snippets, for a method called Login:

    <xs:element name="Login">
            <xs:complexType>
              <xs:sequence>
                <xs:element minOccurs="0" maxOccurs="1" name="username" type="xs:string" />
                <xs:element minOccurs="0" maxOccurs="1" name="password" type="xs:string" />
              </xs:sequence>
            </xs:complexType>
          </xs:element>

       <xs:complexType name="UserInfo">
            <xs:sequence>
              <xs:element minOccurs="0" maxOccurs="1" name="Id" type="xs:string" />
              <xs:element minOccurs="0" maxOccurs="1" name="Name" type="xs:string" />
              <xs:element minOccurs="0" maxOccurs="1" name="Nickname" type="xs:string" />
              <xs:element minOccurs="0" maxOccurs="1" name="Email" type="xs:string" />
            </xs:sequence>
          </xs:complexType>

       <xs:element name="LoginResponse">
            <xs:complexType>
              <xs:sequence>
                <xs:element minOccurs="0" maxOccurs="1" name="LoginResult" type="s0:UserInfo" />
              </xs:sequence>
            </xs:complexType>
          </xs:element>

    Here's a working Login function  that I've added with add SoapServer::addFunction

    function Login($username, $password)
    {
      return array("LoginResult", array("Id"=>1, "Name"=>"Nathan", "Nickname"=>"Nathan", "Email"=>"email address") );
    }

    The UserInfo complextype is represented by the inner array.  The outer array has just one element, "LoginResult".  The LogineResponse element  seems to be treated as a one-member array by PHP.
