preg replace multiple results

I'm currently writing a function in PHP to translate BBCodes for a forum engine. Now I wanted to add a [code]-tag and I created the following function:

$txt = preg_replace('#\[code\](.*)\[(.*)\[/code\]#isU', "<div class=\"bb_uncode\">$1&#91;$2</div>", $txt);

(Side note: &#91; equals [)
This works very well if there's only one [ inside the [code]-tags, but it ignores every further one.
Is there a possiblity to apply this search pattern on every other brackets, too?

Solution

  • Do this with preg_replace_callback():

    $txt = preg_replace_callback('#\[code\](.*)\[/code\]#isU', function($match) {
    return "<div class=\"bb_uncode\">" . 
           str_replace('[', '&#91;', $match[1]) .
           "</div>"); 
}, $txt);
