$ _SESSION变量存储在哪里? [英] Where are $_SESSION variables stored?

问题描述

$_SESSION变量是否存储在客户端或服务器上?

Are $_SESSION variables stored on the client or the server?

推荐答案

$_SESSION变量存储的位置由PHP的session.save_path配置确定.通常在Linux/Unix系统上是/tmp.使用phpinfo()功能(如果不确定100％肯定)来查看您的特定设置，方法是在域的DocumentRoot中创建一个具有以下内容的文件:

The location of the $_SESSION variable storage is determined by PHP's session.save_path configuration. Usually this is /tmp on a Linux/Unix system. Use the phpinfo() function to view your particular settings if not 100% sure by creating a file with this content in the DocumentRoot of your domain:

<?php
    phpinfo();
?>

以下是此配置设置下PHP文档的链接:
