PHP: preg_replace between "<<" and ">>"

Question

Hi I want to replace the content between "<<" and ">>" with custom div class how can I do that?

I tried some regex but It didn't work.

$con = preg_replace ('/<<(.*?)>>/s', '<div>$1</div>', $con);

since you already tried some regex, can you show us what you tried? ;) — Tanuel Mategi

What's the value of $con - I've just literally dropped this into a PHP file and it works : echo preg_replace('/<<(.*?)>>/s', "<div>$1</div>", "<<womble>>"); - it prints out <div>womble</div> — CD001

Shouldn't make any odds, neither < or > are meta characters in RegExp (except for a lookbehind) so there's no reason why that shouldn't work "as-is" ... strange. — CD001

I would propose putting the < and > in character classes:

preg_replace('/[<]{2}(.*?)[>]{2}/s', '<div>$1</div>', $con);

Escaping them should also work

preg_replace('/\<\<(.*?)\>\>/s', '<div>$1</div>', $con);

But CC001's comment above is correct: Neither one of these is needed.
