我有一个正式的代码,但会话变量无法传递给另一个页面。 所以这是我的示例代码。但是,此代码的结果为0。:
第1页代码:
<?php
session_start();
$_SESSION['try'] = 5;
header('Location: page2.php');
?>
第2页代码:
<?php
session_start();
$test = $_SESSION['try'];
echo $test;
?>
答案 0 :(得分:0)
来自manual:
session_start() creates a session or resumes the current
one based on a session identifier passed via a GET or POST request,
or passed via a cookie.
注意最后两行代码:
<?php
// page1.php
session_start();
echo 'Welcome to page #1';
$_SESSION['favcolor'] = 'green';
$_SESSION['animal'] = 'cat';
$_SESSION['time'] = time();
// Works if session cookie was accepted
echo '<br /><a href="page2.php">page 2</a>';
// Or maybe pass along the session id, if needed
echo '<br /><a href="page2.php?' . SID . '">page 2</a>';
?>
