What is the recommended alternative function to use for BBCode formatting in PHP?

The recommended alternative function to use for BBCode formatting in PHP is the `strip_tags()` function. This function allows you to remove any HTML and PHP tags from a string, which can help prevent potential security vulnerabilities such as cross-site scripting (XSS) attacks when dealing with user input.

$bbcode = "[b]Hello, world![/b]";
$cleaned_text = strip_tags($bbcode);
echo $cleaned_text;
