load() Function for PHP - Fetch URL Content

I recently had to develop a small script that will fetch an XML file from the web. All I had to do is download a given URL and read its contents. To my great surprise I found that download the file using my jx Ajax library was much easier than doing it with PHP.

PHP make this very easy by including functions like file_get_contents() that has URL support. Unfortunately, this is a huge security threat - and many servers have disabled this feature in PHP. PHP provide other two method to fetch an URL - Curl and Fsockopen. But to use this I have to write a lot more code. So I decided to create my own function that makes it much more easier.
