<?
// page1.php
session_start();
echo 'Welcome to page #1';
$_SESSION['favcolor'] = 'green';
$_SESSION['animal'] = 'cat';
// Works if session cookie was accepted
echo '<br /><a href="session_get.php">page 2</a>';
// Or maybe pass along the session id, if needed
echo '<br /><a href="session_get.php?' . session_id() . '">page 2</a>';
?>
页面二：
<?
// page2.php
session_start();
echo 'Welcome to page #2<br />';
echo $_SESSION['favcolor']; // green
echo $_SESSION['animal']; // cat
// You may want to use SID here, like we did in page1.php
echo '<br /><a href="page1.php">page 1</a>';
?>
