what you posted is for making a forum tag system, and will not in any way accomplish syntax highlighting for any langauges.

to make syntax highlighting for PHP, you can use the built in highlight_file() or highlight_string() functions. for other languages (xml, html), you can find examples in the comments for highlight_string(). for languages like basic, c-sharp, etc., I'm sure you could base your own functions on them -- or you might be able to find a few via googling.

OP, if you are wanting to highlight bits of code, i suggest using GeSHi
