分享session存取问题,真是急死人大哥大姐你们就同情一下吧
<?
session_start();
$_SESSION["userName"]="admin";
echo $_SESSION["admin"];
?>
1、以上加了session_start();这个方法就报错如下:
Fatal error: session_start(): Failed to initialize storage module: user (path: D:/phpweb/tmp) in D:\phpweb\index.php on line 2
D:/phpweb/tmp //这个路径是存在
2、以下这种方法不会报错，在当前页也可以输出但在另个php页不行了输出为空。
<?
$_SESSION["userName"]="admin";
echo $_SESSION["admin"]; //在当前php页可以输出
?>

我回答你的第二个问题啊：这个是变量的传递问题，你用session，这是一个例子：
1.php
<?php
ob_start();
session_start();
$_SESSION["user"]="lin";
$psid=session_id();
echo "<a href=\"2.php?psid=$psid\"".">"."下一个要传递页面变量的"."</a>";
?>
2.php
<?php
$tmpid=$_GET["psid"];
session_id($tmpid);
session_start();
echo $_SESSION["user"];
//echo $tmpid;
?>
你试一下，希望可以解决你的问题，这个不需要另外配置服务器和php ，就用他们的默认配置就可以了而且还你可以新打开浏览器传递变量！

大佬改了还是不是呀,
session.save_handler = user =>
session.save_handler = file
源码
<?
$_SESSION["userName"]="admin";
echo $_SESSION["userName"]; //在当前php页可以输出，其他页依然为空
?>
session.save_handler = user =>
session.save_handler = file
源码
<?
$_SESSION["userName"]="admin";
echo $_SESSION["userName"]; //在当前php页可以输出，其他页依然为空
?>
