regex

[MeGa_Max]

hi, i have a problem with regex, im trying to change [ b][ /b] to <b></b> with this code

function Format($txt)
{
  $txt = eregi_replace('\[b\](.*)\[/b\]', '<b>\\1</b>', $txt);

  return $txt;
}

But it seems to be greddy and wants to trap more than it needs, to a txt like [ b]bold[ /b] not [ b]bold[ /b] will become <b>bold[ /b] not [ b] bold</b>

After some googling i found the ? ungreediness thing, but if i try to use it

Warning: eregi_replace() [function.eregi-replace]: REG_BADRPT in phpfile.php on line 649

And i also try using preg_replace function instead, but i get

Warning: preg_replace() [function.preg-replace]: Delimiter must not be alphanumeric or backslash in phpfile.php on line 648

Any Ideas?

You can use the "U" (Ungreedy) preg modifier. In this example, I've opted to use "#" as the preg regular expression delimiter.

$txt = preg_replace('#\[b\](.*)\[/b\]#U', '<b>\\1</b>', $txt);
