In PHP forums, is it recommended to allow HTML in user posts or stick to BBCode? What are the advantages and disadvantages of each?

Allowing HTML in user posts can provide more flexibility and customization options for users, but it also opens up security risks such as cross-site scripting (XSS) attacks. On the other hand, sticking to BBCode limits the customization options but helps mitigate security risks by restricting the types of content that can be included in posts. 

// Example code snippet to allow only BBCode in user posts
$userPost = "[b]This is a bold text[/b]";

// Parse BBCode using a library like BBCodeParser
$bbParser = new BBCodeParser();
$parsedPost = $bbParser->parse($userPost);

echo $parsedPost;
