Parsing colorcodes

Hiya fellow PHP coders! I have a problem. I need a function to parse mIRC-colorcodes with PHP. Unfortunaly, I'm not capable to do this myself (or I'm thinking too advanced or something). The code is built like this; chr(3) starts the color formating. After that sign, a series of numbers will come. Can be one or two digits (1-15). 0-9 can have an additional zero before it, like 00-09. Each of these number represents a color. 00 = White 01 = Black 02 = Dark Blue 03 = Dark Green 04 = Red 05 = Marron 06 = Purple 07 = Orange 08 = Yellow 09 = Green 10 = Teal 11 = Cyan 12 = Blue 13 = Magenta 14 = Dark Gray 15 = Gray Now, to make it even worse, it's possible to use a background-color for the text. This is added with a coma. So, the syntax is "X4,8String" where X is really chr(3). Red (4) String with yellow (8) background. The colorparsing can stop when another occurance of chr(3) commes up. Also, the colorparsing ends at the end of line. Please help me on this issue. //Simon
