Question

I need to detect whether a string contains HTML tags.

    return $string;
}

Answer 1

If purpose is just to check if string contain html tag or not. No matter html tags are valid or not. Then you can try this.

function is_html($string) {
  // Check if string contains any html tags.
  return preg_match('/<\s?[^\>]*\/?\s?>/i', $string);
}

This works for all valid or invalid html tags. You can check confirm here https://regex101.com/r/2g7Fx4/3
