XML-RPC

With XML-RPC extension in PHP , you can use this library to buile a data interaction between client side and server side , it use XML to get or response data .

 

rpc_client.php

<?php/** * The function which supply to connect to server port * $host the connect host* $port the connect port* $rpc_server XML-RPC file in server port * $request the XML request info* @return if connect success will return server XML info* and if connect not correct will return false*/function rpc_client_call($host, $port, $rpc_server, $request) { //open appinoted server port $fp = fsockopen($host, $port); //generate a POST request info to XML-RPC server port $query = "POST $rpc_server HTTP/1.0/nUser_Agent: XML-RPC Client/nHost: ".$host."/nContent-Type: text/xml/nContent-Length: ".strlen($request)."/n/n".$request."/n"; //send the http protocol to server , lose return false1 if (!fputs($fp, $query, strlen($query))) { $errstr = "Write error"; return false; } //get all the info received from server side, include HTTP header and XML info $contents = ""; while (!feof($fp)) { $contents .= fgets($fp); } //close connect and return content fclose($fp); return $contents;} //create RPC connect info $host = "localhost"; $port = 80; $rpc_server = "/test/rpc_server.php";//encode the request to XML , method rpc_server , paramter get$request = xmlrpc_encode_request("rpc_server", "get");//invoke function rpc_client_call $response = rpc_client_call($host, $port, $rpc_server, $request);//analyse the data $response , clear the HTTP header and transform to PHP string//beware of the single quota or double quota in the belowe string so important$split = '<?xml version="1.0" encoding="iso-8859-1"?>';$xml = explode($split, $response);$xml = $split . array_pop($xml);$response = xmlrpc_decode($xml);//output the info get from server portprint_r($response);?> 

 

rpc_server.php

<?php /** * the function be called by client* $method the function be called by client* $params the function parameter be called by client* @return string*/function rpc_server_func($method, $params) {$parameter = $params[0]; if ($parameter == "get") { $return = "This data by get $method"; } else { $return = "Not specify method or params"; } return $return; } //create a XML-RPC server side$xmlrpc_server = xmlrpc_server_create(); //register a server side function rpc_server , but actually point to function rpc_server_funcxmlrpc_server_register_method($xmlrpc_server, "rpc_server", "rpc_server_func"); //get the POST data from client$request = $HTTP_RAW_POST_DATA;//execute XML request from client and get the result$xmlrpc_response = xmlrpc_server_call_method($xmlrpc_server, $request, null); //echo the resultheader("Content-Type: text/xml"); echo $xmlrpc_response; //destroy XML-RPC resourcexmlrpc_server_destroy($xmlrpc_server);  

 

The example above are just use xmlrpc extension , 

and for the advance , there has a library XML-RPC for PHP in
