ENC28J60 + MySQL

Hey guys, I'm pretty new here. So, I'll go ahead and tell my thing.
I recently bought an ENC28J60 module which is for Ethernet. I tried almost every tutorial on ho to connect it to a MySQL db and doesn't work with PHP, obviously. But, I tried to use Arduino as server and works fine, it doesn't make sense.
I have:
Arduino UNO board.
Can anyone help me?
Thank you so much.
