preg replace (again -.-)

[eluser]Pascal Kriete[/eluser]
Use preg_replace_callback if you need to process one of the captured strings.

Code:

$layout = preg_replace_callback('~{(.+?)}~', array($this, 'replace_function'), $layout);

function replace_function($matches)
{
    $match = $matches[1]; // 0 is the whole thing, 1 is the first subpattern
    
    // Do something with $match

    return '<div class="'.$matches[1].'">'.$match.'</div>';
}
