I have created my personal login system. I am kinda newbee here. When user log in it creates cookie as 'user'. I've seen some sites to which creates password cookies too. So i need to verify both the cookies in mysql database every time with the every page loads? And some browser allows us to see cookies and change the values of it. So if go and change 'user' value to another user so it can display information of other user. So can any one help me to solve this? Programming should be done in php.
Thanks in advanced.
