What are the best practices for removing specific HTML tags while preserving others in PHP?

When removing specific HTML tags while preserving others in PHP, one approach is to use the strip_tags() function with the exception parameter to specify the tags that should not be removed. This allows you to selectively remove certain tags while keeping others intact. 

// HTML content with specific tags to preserve and remove
$html = '<div><p>Hello</p><a href="#">Link</a><script>alert("Hello")</script></div>';

// Remove all tags except <p> and <a>
$cleaned_html = strip_tags($html, '<p><a>');

echo $cleaned_html;
