Need a guidance of signature condition in php forum

I wanna know that how do i put a signature in php forums? like great than 5 comments you can put the signature like that. Please and how is it working. Explain. I really appreciate all who answers.

You can set a signature after you’ve been a member here for 90 days.

There already are a bunch of threads with this question out there so I’ll just close this one now :slight_smile:
