在表中插入PHP代码但在页面上不起作用？

I was testing some code in MySQL db. I have a user have privilege to insert data in table and the columns are appearing in some page on my site

So I decided to insert PHP code on table

<?php phpinfo();?>

But when I try to load it on page, it shows a blank. How can I insert a PHP code and let it execute on page? Is this possible?
