How can I test my PHP MySQL injection example?

Question

I want to use PHP/Mysql injection with a login example, my code is below.

I have tried with a username of anything\' -- and an empty password but it doe

Answer 1

If the value of username is:

 $_POST['user'] = "1' OR 1 LIMIT 1; --";

Then the mysql query becomes:

select * 
from zend_adminlist 
where user_name = '1' OR 1 LIMIT 1; --' and password = '$pass'
