You don't appear to have write permission to the /tmpdirectory on your server. This is a bit weird, but you can work around it. Beforethe 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.
您似乎没有/tmp对服务器上的目录的写权限。这有点奇怪，但你可以解决它。之前调用session_start()投入到呼叫session_save_path()，并给它由服务器写入的目录的名称。详细信息在这里。

do a phpinfo(), and look for session.save_path. the directory there needs to have the correct permissions for the user and/or group that your webserver runs as
执行 phpinfo()，然后查找 session.save_path。那里的目录需要对您的网络服务器运行的用户和/或组具有正确的权限

I have had this issue before, you need more than the standard 755or 644permission to store the $_SESSIONinformation. You need to be able to write to that file as that is how it remembers.
我以前遇到过这个问题，您需要的不仅仅是存储信息的标准755或644权限$_SESSION。您需要能够写入该文件，因为它是这样记住的。

It seems that you don't have WRITE permission on /tmp.
您似乎没有 WRITE 权限/tmp。
Edit the configuration variable session.save_pathwith the function session_save_path()to 1 directory abovepublic_html(so external users wouldn't access the info).
使用函数session_save_path()将配置变量session.save_path编辑到上面的 1 个目录（因此外部用户不会访问信息）。public_html

PHP does not have permissions to write on /tmp directory. You need to use chmodcommand to open /tmp permissions.
PHP 无权写入 /tmp 目录。您需要使用chmod命令来打开 /tmp 权限。
