有没有办法确定*实际*会话保存路径? [英] Is there any way to determine the *actual* session save path?

问题描述

我知道有六种方法可以获取 session.save_path 指令的值(phpinfo(), session_save_path()等)，但当值为空字符串时，默认情况下，实际路径可以是多个位置中的任何一个.我读过它通常是 /tmp，除非它是 /var/lib/php5，但在 OS X Mountain Lion 上它绝对是 /private/var/tmp.在 Windows 上，它可能是 C:\Windows\Temp，但谁知道呢.

I know there are half a dozen ways to get the value of the session.save_path directive (phpinfo(), session_save_path(), etc.), but when the value is an empty string, as it is by default, the actual path can be any of several locations. I've read that it's usually /tmp, except when it's /var/lib/php5, but on OS X Mountain Lion it's definitely /private/var/tmp. On Windows, it's probably C:\Windows\Temp, but who knows.

我可以指定位置，但这对我没有帮助.我正在尝试诊断一个棘手的问题，我想知道我没有完全访问权限的服务器上的当前位置.如果有正确的方法来做到这一点，我还没有找到.我对聪明的黑客持开放态度.

I could specify the location, but that won't really help me. I'm trying to diagnose a tricky problem and I would like to know what the current location is on a server that I don't have full access to. If there's a right way to do it, I haven't been able to find it. I'm open to clever hacks.

推荐答案

我还没有查看 PHP 源代码来确认这一点，但是看起来当 session.save_path 为空时，PHP 使用sys_get_temp_dir() 的值(因用户而异).

I have not reviewed the PHP source code to confirm this, but it looks like when session.save_path is empty, PHP uses the value of sys_get_temp_dir() (which varies by user).
