How to use php preg_replace to replac

Answer 1

It is almost never a good idea to use regular expressions for HTML. Consider DOM, then something like:

foreach($dom->getElementsByTagName('script') as $script) {
    $temp = $dom->createElement('temp');
    /*
     * create src attribute, append it to $temp and copy value from $script
     * I leave that up to you.
     */
    $script->parentNode->replaceChild($temp, $script);
}
