[SOLVED] [PCRE] Find and replace <? with <?php

[Vinze]

Hey, I want to use preg_replace() to replace all instances of <? with <?php. I can't do this with str_replace() because when I [i]do[/i] use <?php it would be converted to <?phpphp. I tried the following pattern:
[code]
[<\?(!(php))][/code]

But that doesn't work. Please help me, thanks in advance.

[b]Edit:[/b] And I learned something new today: lookaheads. The correct code was:

[code]
[<\?(?!php)][/code]
