How to show delete and edit button for logined in user in PHP

Question

Hi guys I'm working on simple BBS in PHP and I have problem with it. I wanted to get delete and edit button if user logged in BBS. For example if person A logged in BBS I want to show delete and edit button only for person A that posted article but I don't want show them for other users. I tried to make code but it didn't work and first of all I'm not sure this code is correct or not... If you have any advice or idea I really appriciate! Thank you!
