$_SESSION['variable_name_here']
How do you Use SESSION variables in PHP?
The short text that you see in the footer (Statusbar) of these pages are made using a variable.
The variable is called a $_SESSION['variable_name_here'];
The things about this is that it can help you carry values from one page to another in your project.
You have to insert a special tag in the top of the pages if you are to use this though. That tag looks like so;
<?php session_start(); ?>
Remember that it have to be the very first content on the page where you want to use SESSION variables.
Let's say that you have a user login on one page, and want to carrry the users name onto another page, where you are to use that, then do something like this;
$_SESSION['usersname'] = $_POST['usersname'];
Then you can recall that value on another page, if you were to use the users name there.
echo $_SESSION['usersname'];
