What are some best practices for handling user input from editors like CKEditor and TinyMCE in PHP?

When handling user input from editors like CKEditor and TinyMCE in PHP, it is important to sanitize the input to prevent cross-site scripting attacks and other security vulnerabilities. One way to do this is by using the htmlspecialchars() function to escape special characters. Additionally, you can use strip_tags() to remove any HTML tags that are not allowed. 

// Sanitize user input from CKEditor or TinyMCE
$clean_input = htmlspecialchars($_POST['editor_input']);
$clean_input = strip_tags($clean_input, '<p><a><strong><em><ul><ol><li>'); // Allow only specific HTML tags

// Use $clean_input in your application
echo $clean_input;
