$output = strtolower(preg_replace('~\d\K(?=[A-Z])|-~', '_', $input));

\K removes that is matched on the left from the match result, so , the digit before the letter is not a part of the match and will not be replaced.

(?=...) is a lookahead assertion that checks if a letter if following, it isn't a part of the match result too and will not be replaced too.

I'm a noob in regular expressions but I`ll give it a shot.

Input: /([A-Z]+)\d+([A-Z]+)\-([A-Z]+)/

A-Z matches uppercase alpha characters \d matches numbers

"+" is used to repeat

And in the replacement callback use strtolower on the matches and join them how you want :P
