(PHP 5 >= 5.0.1, PHP 7)
SoapServer::addFunction — Adds one or more functions to handle SOAP requests
Exports one or more functions for remote clients
functionsTo export one function, pass the function name into this parameter as a string.
To export several functions, pass an array of function names.
To export all the functions, pass a special constant SOAP_FUNCTIONS_ALL.
Note:
functionsmust receive all input arguments in the same order as defined in the WSDL file (They should not receive any output parameters as arguments) and return one or more values. To return several values they must return an array with named output parameters.
No value is returned.
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.
