What are some key security considerations when choosing a WYSIWYG editor for PHP usage?

When choosing a WYSIWYG editor for PHP usage, it is important to consider security vulnerabilities such as Cross-Site Scripting (XSS) attacks. To mitigate this risk, ensure that the editor has built-in sanitization features to strip out any potentially harmful code before displaying user input. 

// Example of using htmlspecialchars() function to sanitize user input before displaying it with a WYSIWYG editor
$user_input = "<script>alert('XSS attack!');</script>";
$sanitized_input = htmlspecialchars($user_input);
echo $sanitized_input;
