By default, session data is stored in a file in /tmp, but you can specify
another place, like a database. PHP generates a session id, which is part of
the filename of the session file. PHP passes a cookie containing the session
id to the browser, so that PHP can keep track of which session file belongs
to which browser request.
Below is an example script along with its associated session file.

<?
session_start();
$a = "MickeyMantle";
$b = 7;
$c = 3.14159;
$d = array(7,8,9);
$e = array('spot' => 'dog',
'fluffy' => 'kitty',
'mighty' => 'mouse');
$f = 0;
$g = '0';
session_register('a','b','c','d','e','f','g','h');
?>
session_file:/tmp/sess_37c7968b6da03aadb9e5449428a67a2d
