CAML Encode and Decode

url encode 
Use the CAML encoder and decoder to encode or decode CAML while working with SharePoint Data Source Control queries. This script utilizes both HTML rendering to decode and a PHP function to encode. And, of course, I have included the simple script below for those that are curious.

<p style="text-align:center;font-family:verdana;font-size:12px;">note: the decode utilizes standard HTML rendering and the encode will only change the following characters (", <, >).</p>

You may think nerd...I think developing a new trend!
