php login without session
php login with session --> this one is good
follow the tutorial until you succeed.
*or you can find others..there a lot examples
SECONDLY, make up your login page to look good, i mean you can find a style that you want. So you have to find a LOG IN TEMPLATE. Here some links that you can refer to:
