PHP: Can I use Arrays as Session Variables?

PHP also supports arrays as session variables.

You can just assign an array to any session variable like this:

$arr = array(1, 2, 3);
session_start();
$_SESSION['arr'] = $arr;

Or you can directly create your array in the session variable:

session_start();
$_SESSION['arr'] = array(1, 2, 3);

Accessing the array can be done like this, for example:

echo $_SESSION['arr'][0];  // 1

However, you can just use your session array variable like any other local array variable, too.
