What are some common pitfalls to avoid when working with WYSIWYG editors in PHP?

One common pitfall when working with WYSIWYG editors in PHP is the vulnerability to Cross-Site Scripting (XSS) attacks if user input is not properly sanitized. To prevent this, always use htmlspecialchars() function to escape user input before displaying it on the page. 

// Sanitize user input before displaying it
$user_input = "<script>alert('XSS Attack!')</script>";
echo htmlspecialchars($user_input, ENT_QUOTES, 'UTF-8');
