(PHP 5, PHP 7)
SoapServer::addFunction — 添加一个或多个函数来处理SOAP请求
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。
没有返回值。
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.
