Are there any performance considerations to keep in mind when using regex to remove HTML tags in PHP?

When using regex to remove HTML tags in PHP, it's important to consider the performance implications, especially when dealing with large strings or complex HTML structures. One way to improve performance is to use the PHP built-in function `strip_tags()` instead of regex, as it is specifically designed for this purpose and is more efficient. However, if you still prefer to use regex, make sure to optimize your regex pattern to be as specific as possible to avoid unnecessary processing. 

// Using strip_tags() function for better performance
$cleanedString = strip_tags($htmlString);

// Using regex to remove HTML tags
$cleanedString = preg_replace('/<[^>]*>/', '', $htmlString);
