    "'<pre class='.stripslashes('$1').'prettyprint '.stripslashes('$2').'>'.htmlentities(stripslashes('$3')).'</pre>'", 
    $text);

with

return preg_replace_callback(
    "/<pre\\s*class\\s*=\\s*([\"'])\\s*prettyprint\\s*([^>]*?)\\s*>(.*?)<\/pre>/is", 
    function($matches){
            return '<pre class=' . stripslashes($matches[1]) .'prettyprint ' . stripslashes($matches[2]). '>' . htmlentities($matches[3]) .'</pre>';

    function($matches){
        return '<pre class=' . stripslashes($matches[1]) . stripslashes($matches[2]) . 'trigger '  . stripslashes($matches[2]) . stripslashes($matches[3]) . '>'; 
    } 
    , $text);
