Recently I played with php xml rpc library. My main goal is to post articles from php to wordpress blog.

There are a lot of implementation on the web.

First I tried the one on sourceforge.

http://phpxmlrpc.sourceforge.net/

I use the library to develop method to post a new articles or edit an existing article on a wordpress blog.

The sample code is like  this:

 $content['title'] = ”A post”
 $content['description'] = $article;
 $content['categories'] = “General”;
  $c = new xmlrpc_client(“/xmlrpc.php”, “localhost”, 80);
   $x = new xmlrpcmsg(“metaWeblog.newPost”,
       array(php_xmlrpc_encode(“1″),
       php_xmlrpc_encode($blogUser),
       php_xmlrpc_encode($blogPass),
       php_xmlrpc_encode($content),
       php_xmlrpc_encode(“1″)));
   $c->return_type = ‘phpvals’;
   $r =$c->send($x);
   if ($r->errno==”0″)
   {
    echo “Successfully Posted! articel ID:”;
    print $r->val;
   }
   else
   {
     echo “xmlrpc meets some error”;
     print_r($r);
   }

But when I tried to implement uploading images with metaWeblog.newMediaObject method, the library cannot support base64 value encoding correctly.

Then I realized the library used by wordpress itself should be a good candidate. It is actually from here: http://scripts.incutio.com/xmlrpc/beginners.php

$client = new IXR_Client(‘http://scripts.incutio.com/xmlrpc/simpleserver.php’);
if (!$client->query(‘test.getTime’)) {
   die(‘An error occurred – ‘.$client->getErrorCode().”:”.$client->getErrorMessage());
}
print $client->getResponse();

This library is more easily to use. Highly recommended!
