PHP Remove JavaScript

Question

I am trying to remove JavaScript from the HTML.

I can\'t get the regular expression to work with PHP; it\'s giving me an null array. Why?

Answer 1

I use this:

function clear_text($s) {
    $do = true;
    while ($do) {
        $start = stripos($s,'<script');
        $stop = stripos($s,'</script>');
        if ((is_numeric($start))&&(is_numeric($stop))) {
            $s = substr($s,0,$start).substr($s,($stop+strlen('</script>')));
        } else {
            $do = false;
        }
    }
    return trim($s);
}
