How can strip_tags and trim functions be optimized to ensure all unnecessary spaces are removed from a PHP string?

To optimize the strip_tags and trim functions to ensure all unnecessary spaces are removed from a PHP string, you can use trim with a regular expression to remove extra spaces before and after tags are stripped. This way, you can ensure that there are no unnecessary spaces left in the string after removing HTML tags. 

// Original string with HTML tags and extra spaces
$string = "<p>   Hello,   world!   </p>";

// Remove HTML tags and extra spaces
$cleaned_string = trim(preg_replace('/\s+/', ' ', strip_tags($string)));

echo $cleaned_string; // Output: Hello, world!
