[PHP] Ask for help on a mysql problem

I wanna setup a tree structure. Each node in this tree is a table. Each table has a link field. For each record, the data in this field is a pointer to another table or null. I read mysql manual but don't find any clues that SQL supports such a link field. Does anyone has an idea about that?
