PHP5禁用COOKIE后SESSION还能用吗?

<?php

//c.php页面

session_start ();

$_SESSION ['test'] = 'test';

echo 'session["test"]=' . $_SESSION ['test'];

?>

<a href="d.php?<?php echo htmlspecialchars(SID);?>">D</a>

<?php

//d.php页面

$sid = $_GET ['PHPSESSID'];

session_id ( $sid );

session_start ();

echo 'session["test"]=' . $_SESSION ['test'];
