Using Xmlrpc in PHP

PHP is simple to use XMLRPC, the server side and the client are all PHP code implementation.

The XML-RPC used here fully includes the XML-RPC implementation of the client and server.
The client and server side are implemented by the Xmlrpc_client class and the Xmlrpc_server class, and are mainly used for receiving and sending XML-RPC messages.

Client:

The Xmlrpcval class is used to encode PHP variables as XML-RPC equivalent data types and to pass parameters to remote methods. The opposite procedure uses the Xmlrpc_decode () function.

The Xmlrpcmsg class creates a XML-RPC message by passing it a parameter table.
The Xmlrpc_client class sends XML-RPC messages created using the Xmlrpcmsg class.

Server-side:

The Xmlrpc_server class parses these received messages (Xmlrpcmsg objects) as PHP variables.

It is then passed as a separate parameter to the user function, which must return a Xmlrpcresp object.

The Xmlrpc_server class uses it for serialization and returns it to the client.

Server side: xmlrpc_s.php

<?PHP/*XMLRPC Server (PHP version)*/require"Libphpxmlrpc/xmlrpc.inc";require"Libphpxmlrpc/xmlrpcs.inc";functionSaySomething ($msg) {//decodes a parameter from a MSG object into a variable $words= Php_xmlrpc_decode ($msg->getparam (0)); //return Results if(strlen($words) > 0)  {     return NewXMLRPCRESP (NewXmlrpcval (' Server say: '.$words, ' string '));//returned to the customer } Else {       return NewXmlrpcresp (0,$xmlrpcerruser+, "paras".$words. "' Understand."); //error returned to the customer, of course, you can not return//if there is any wrong parameter AH system will return error//$xmlrpcerruser + 100 This is the error code to return customer custom errors// When developing the RPC program, it is best to define an error table. The error number displayed by the client is }}//set up a server$s=NewXmlrpc_server (Array(' say ' =Array(' function ' = ' saysomething ',//command corresponds to the function to be called' Signature ' =Array(Array(' String ', ' string '),//returns the input data type, a function can have several input and output types' DocString ' = ' This service echoes Hello+input stirng. '),//description of the call0//This parameter determines that the service is not immediately opened at this time );//Setting Parameters$s->response_charset_encoding = "UTF-8"; //Open Service $s-service ();?>

Client: xmlrpc_c.php
