Quickly, $ _SESSION and $ _COOKIES are used to store information.

$ _SESSION stores the information on the server, so it is safer and generally used for logins and passwords.

$ _COOKIES stores the information in your user's browser and is most often used to store user preferences, shopping cart, etc.
