I tested this function, it works for nested tags too, use true/false to exclude/include your tags. Found here: https://www.php.net/manual/en/function.strip-tags.php

/si', trim($tags), $tags);
  $tags = array_unique($tags[1]);
   
  if(is_array($tags) AND count($tags) > 0) {
    if($invert == FALSE) {
      return preg_replace('@<(?!(?:'. implode('|', $tags) .')\b)(\w+)\b.*?>.*?@si', '', $text);
    }
    else {
      return preg_replace('@<('. implode('|', $tags) .')\b.*?>.*?@si', '', $text);
    }
  }
  elseif($invert == FALSE) {
    return preg_replace('@<(\w+)\b.*?>.*?@si', '', $text);
  }
  return $text;
}




// Sample text:
$text = 'sample text with 
tags
';

echo strip_tags_content($text);
// text with

// sample text with
