Forum Number of Private Messages

[محروم.كوم]

Is there a way in PHP to show the amount of unread private messages the user has? Maybe a MySQL statement or something? I made a custom link in the navigation manager. The current title is "View Private Messages" and I think it would be cool to have it something like "View Private Messages (0)" or whatever number the user has unread. The thing I'm not sure of is how to code it, and if the link title in the navigation manager supports PHP. __DEFINE_LIKE_SHARE__
