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

function clean_jscode($script_str) {
    $script_str = htmlspecialchars_decode($script_str);
    $search_arr = array('');
    $script_str = str_ireplace($search_arr, $search_arr, $script_str);
    $split_arr = explode(' $val) {
        $newarr = explode('', $split_arr[$key]);
        $remove_jscode_arr[] = ($key == 0) ? $newarr[0] : $newarr[1];
    }
    return implode('', $remove_jscode_arr);
}
