First you need to install XML _RPC and VAR _DUMP:

Installing XML _RPC

   1  pear install XML_RPC
   2  pear install VAR_DUMP

Example XML -RPC client

Note this code hasn’t been tested, so may contain errors.

Anyway, VAR _DUMP is great for debugging…

   1  <?php
   2    require_once("XML/RPC.php");
   3    require_once('Var_Dump.php');
   4  
   5    Var_Dump::displayInit(array('display_mode' => 'HTML4_Text'), array('mode' => 'normal','offset' => 4));
   6    
   7    $host = "xxx.com";
   8    $uri = "/xxx/xmlrpc";
   9  
  10    $function   = "eat";
  11    $parameters = array(
  12      new XML_RPC_Value("a"),
  13      new XML_RPC_Value(0),
  14      new XML_RPC_Value(10),
  15      new XML_RPC_Value("b")
  16    );
  17    
  18    $message = new XML_RPC_Message($function, $parameters);
  19      
  20    $client = new XML_RPC_Client($uri, $host, 80);
  21    $client->setDebug(1);
  22    $client->proxy = "127.0.0.1";
  23  
  24    $result = $client->send($message);
  25  
  26    if (!$result) {
  27      echo 'Communication error: '.$client->errstr;
  28  	Var_Dump::display($client);
  29      exit;
  30    }
  31  
  32    if($result->faultCode())
  33    {
  34       echo "** ERROR **n";
  35       echo 'Fault Code: ' . $result->faultCode() . "n";
  36       echo 'Fault Reason: ' . $result->faultString() . "n";
  37       exit;
  38    }
  39  
  40    echo "<pre>".htmlentities($message->serialize()). "</pre>";
  41  
  42    Var_Dump::display($result);
  43  
  44    $val = $result->value();
  45    $ticket = $val->scalarval();
  46    
  47    echo $ticket;
  48  ?>
  49  

Data types

struct

   1  $user_params =  array(
   2  	'username' 	  	 => new XML_RPC_Value(".."),
   3  	'email' 	 	 => new XML_RPC_Value("..."),
   4  	'time'  => new XML_RPC_Value(gmdate("Ymd\TH:i:s"), 'dateTime.iso8601')
   5  	);
   6  
   7  $rpc_param = new XML_RPC_Value($user_params, 'struct')

dateTime.iso8601

   1  'time'  => new XML_RPC_Value(gmdate("Ymd\TH:i:s"), 'dateTime.iso8601')
