[RESOLVED] Reg Exp Help

[ahundiak]

I need an expression that will search backwards through a string and break the string at the first upper case letter returning both halves of the string. However, an underscore anywhere in the string should cause the expression to fail.

Example:
PhyTeamItem => PhyTeam and Item
PhyTeamModel => PhyTeam and Model

PhyTeam_Model => fails

Easy enough to write a little function and scan the string but I assume regular expressions woud be faster and look cooler.

Thanks in advance.

This is the best I can do. There is a way to do a conditional in a regexp but I don't know it.

$new_string = (ereg("_",$string)) ? "" : ereg_replace("([A-Z])"," \1",$string);

$newText = preg_replace('/^([^_]*)([A-Z][^A-Z_]*)$/', '\\1 \\2', $text);

Thanks. They worked fine. Someday I'm going to learn expressions.
