SoapServer::addFunction

(PHP 5, PHP 7)

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

说明

public SoapServer::addFunction ( mixed $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.

Note:
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。

范例

Example #1 SoapServer::addFunction() example


<?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.
