Sanitize Script Tags Before Saving To Db

the problem with the script tag arrows is that they can have more than one variant

(< = `&lt;` = `&amp;lt;`) & ( > = `&gt;` = `&amp;gt;`)

so instead of creating a pattern array with like a bazillion variant,
imho a better solution would be

// $text = input u want to clean
public function cleanHTML($text)
{
  $pattern = [
      '/script.*?\/script/ius'

      // or even better one

      '/(script.*?\/script)|[^a-zA-Z0-9]+/ius'
  ];

  return preg_replace($pattern, '', $text)
  ? preg_replace($pattern, '', $text)
  : $text;
}

** if anyone have a better idea, please do advice.
