10.3.3 Reading session data

This is NOT the latest copy of this book; click here for the latest version.

Once you have put your data safely away, it becomes immediately available in the $_SESSION superglobal array with the key of the variable name you gave it. Here is an example of setting data and reading it back out again:

<?php

      $_SESSION['foo'] = 'bar';

      print $_SESSION['foo'];
 ?>

Unlike cookies, session data is available as soon as it is set, which can be quite an advantage.
