The following script shows how to implement an XML-RPC server using PHP.
<?php include 'xmlrpc.inc'; include 'xmlrpcs.inc'; function sumAndDifference ($params) { // Parse our parameters. $xval = $params->getParam(0); $x = $xval->scalarval(); $yval = $params->getParam(1); $y = $yval->scalarval(); // Build our response. $struct = array('sum' => new xmlrpcval($x + $y, 'int'), 'difference' => new xmlrpcval($x - $y, 'int')); return new xmlrpcresp(new xmlrpcval($struct, 'struct')); } // Declare our signature and provide some documentation. // (The PHP server supports remote introspection. Nifty!) $sumAndDifference_sig = array(array('struct', 'int', 'int')); $sumAndDifference_doc = 'Add and subtract two numbers'; new xmlrpc_server(array('sample.sumAndDifference' => array('function' => 'sumAndDifference', 'signature' => $sumAndDifference_sig, 'docstring' => $sumAndDifference_doc))); ?>
You would normally invoke this as something like http://localhost/path/sumAndDifference.php.
