12.9. Receiving SOAP Requests
Problem
You want to create an SOAP server and respond to SOAP requests. If your server responds to SOAP requests, anyone on the Internet that has a SOAP client can make requests of your server.
Solution
Use PEAR’s
SOAP_Server
class. Here’s a server
that returns the current date and time:
require 'SOAP/Server.php'; class pc_SOAP_return_time { var $method_namespace = 'urn:pc_SOAP_return_time'; function return_time( ) { return date('Ymd\THis'); } } $rt = new pc_SOAP_return_time( ); $server = new SOAP_Server; $server->addObjectMap($rt); $server->service($HTTP_RAW_POST_DATA);
Discussion
There are three steps to creating a SOAP server with
PEAR’s SOAP_Server
class:
Create a class to process SOAP methods and instantiate it
Create an instance of a SOAP server and associate the processing object with the server
Instruct the SOAP server to process the request and reply to the SOAP client
The PEAR SOAP_Server
class uses objects to handle
SOAP requests. A request-handling class needs a
$method_namespace
property that specifies the SOAP
namespace
for the class. In this case, it’s
urn:pc_SOAP_return_time
. Object methods then map
to SOAP procedure names within the namespace. The actual PHP class
name isn’t exposed via SOAP, so the fact that both
the name of the class and its $method_namespace
are identical is a matter of convenience, not of necessity:
class pc_SOAP_return_time { var $method_namespace = 'urn:pc_SOAP_return_time'; function return_time( ) { return date('Ymd\THis'); ...
