Re: [PHP] Hex2Bin??
Although the first comment was not what I needed, I did find another built-in function that converts between any base, base_convert($number, $frombase, $tobase) worked wonderful for what I needed.

Re: [PHP] Hex2Bin??
I'd recommend writing a wrapper around base_convert, naming it hex2bin and using that instead. base_convert() is way too expensive for this purpose (you know that any hex figure is translated to exactly four bits, so you don't need any actual conversion - just replacement). This is why I suggested the wrapper - you can change the code at any time if you see it's too time-consuming...

Re: [PHP] Hex2Bin??
Perhaps you could use something a little more KISS- like rawurldecode(chunk_split ( $hexstring, 2 , %)) not sure if it would be faster than base_convert or not, but it wouldn't be too hard to find out.
