Remote Procedure Calls with PEAR::XML-RPC - Server Rewritten Example
(Page 7 of 12 )
Now it's time to explore a server component capable of handling the XML-RPC message. PEAR::XML-RPC also provides us an easy way to do this:
<?php
require_once("XML/RPC/Server.php");
$getnamelength_sig = array(array("int", "string", "string"));
$getnamelength_doc = "Accepts two string parameters, joins them and then returns the length of the resulting string.";
function getnamelength($msg) {
$name1 = $msg->getParam(0);
$name2 = $msg->getParam(1);
$length = strlen($name1->scalarval() . $name2->scalarval());
$result = new XML_RPC_Value( $length, "int");
return new XML_RPC_Response($result);
}
$map = array("getNameLength" =>
array("function" => "getnamelength",
"signature" => $getnamelength_sig,
"docstring" => $getnamelength_doc));
new XML_RPC_Server($map); |
The XML/RPC/Server.php class is included from the PEAR library. The server class imports the functionality of XML/RPC.php, so you only need just the one include.
<?php
require_once("XML/RPC/Server.php");
?> |
