Alpha Wordpress Plugin for Delicious with Zend Framework's Zend_Service_Delicious

I have Wordpress set up on PHP5. While Wordpress is largely a PHP4 entity, I wanted to see if it could play nicely with the Zend Framework, which is a PHP5-only entity. With some careful fiddling, it works pretty well.

With my Zend Framework code set up in my PHP include path, the first thing I needed to do to create a Wordpress Plugin was to enable my plugin to call the Zend Framework classes. First I tried this towards the end of my wp-config.php file:

require_once 'Zend/Loader.php'; 
function __autoload($class) 
{ 
  Zend_Loader::loadClass($class); 
} 

This caused Wordpress to freak out like a chihuahua on speed. Not good. I figured we'd have to do something special because we don't want ALL the classes to autoload, just the Zend ones. So I scrapped my previous __autoload and tried this instead:

require_once 'Zend/Loader.php'; 
function __autoload($class) 
{ 
  $pos = strpos($class, 'Zend'); 
  if ($pos !== false) 
  { 
    Zend_Loader::loadClass($class); 
  } 
} 

Ahh, success. Sweeter then a brownie sundae with extra chocolate sauce.

From there, the rest is easy. Here's some basic code for the rz_delicious plugin, a basic PHP file you can drop into your Wordpress Plugins dir. It uses Zend_Cache and Zend_Service_Delicious to put your del.icio.us bookmarks onto your Wordpress blog. It first checks to see if there's a cached version already, if not, it uses the del.icio.us API to fetch your latest bookmarks. It does some list formatting there too because I didn't feel like handling that in my theme.
