问题描述
可能的重复:
如何修复权限错误我调用 session_start()?
我收到以下错误:
PHP Warning: session_start() [<a href='function.session-start'>function.session-start</a>]: open(/tmp/sess_49a20cbe1ef09a2d0262b3f7eb842e7b, O_RDWR) failed: Permission denied (13) in /home/------/public_html/includes/libs/ss.inc.php on line 1
问题不会一直发生，而是来来去去.
The problem doesn't happen all the time, but comes and goes.
这是 ss.inc.php 中第 1 行的代码
This the code at line on 1 in ss.inc.php
<?php session_start(); ?>
推荐答案
您似乎没有对服务器上的 /tmp 目录的写权限.这有点奇怪，但你可以解决它.在调用 session_start() 之前，调用 session_save_path() 并为其指定服务器可写的目录的名称.详情在此处.
You don't appear to have write permission to the /tmp directory on your server. This is a bit weird, but you can work around it. Before the call to session_start() put in a call to session_save_path() and give it the name of a directory writable by the server. Details are here.
