If you're just getting started with PHP, some things can be a bit confusing. For a lot of developers, sessions seem to hold a bit of mystery and can be difficult to use. To help combat this, PHP F1 has posted this new tutorial to demystify this super-handy PHP functionality.
In this tutorial I will show you how to work with sessions in PHP. You will learn how to transfer information between pages. [...] Using sessions you can transfer data between various pages. If you are using sessions then each of your visitors will got a unique id. This id will identify various visitors and with the help of this id are the user data stored on the server.
They introduce what sessions are (the concept behind them), some of the php.ini settings that can be used to change how they work and code to work with assigning values to a session, checking for values in them and removing/destroying the session and its information.
