Are you creating and closing the session?
Does the correct file path exist and is it writeable? (You are using windows, right?)
我也建议从西经共体行政屏幕上检查营地组合,以确保会议信息正确。 如果你改变道路,就必须重新启用网络服务器。
例: http://php.net/manual/en/Function.session-start.php。
<?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> ;
?>
页: 1
<?php
// page2.php
session_start();
echo Welcome to page #2<br /> ;
echo $_SESSION[ favcolor ]; // green
echo $_SESSION[ animal ]; // cat
echo date( Y m d H:i:s , $_SESSION[ time ]);
// You may want to use SID here, like we did in page1.php
echo <br /><a href="page1.php">page 1</a> ;
?>
