仅在GoDaddy上发出PHP Session问题（警告：session_start（）：无法发送会话cookie）

Question

I am currently working on a user registration system for a client on GoDaddy hosting.

I have previously never had this sort of issue before on Hostgator and while testing locally on a PHP test server on OS X.

It's a fairly simple script too. common.php accesses the MySQL database, all of the pages (login, register, etc.) include common.php. Sessions start when the user logs in, etc.

I see the following errors at the top of the page:

Warning: session_start(): open(/home/content/10/12114910/tmp/sess_trmok9fgtb527mjp21a76shf54, O_RDWR) failed: No such file or directory (2) in /home/content/10/12114910/html/common.php on line 86

Warning: session_start(): Cannot send session cookie - headers already sent by (output started at /home/content/10/12114910/html/common.php:86) in /home/content/10/12114910/html/common.php on line 86

Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /home/content/10/12114910/html/common.php:86) in /home/content/10/12114910/html/common.php on line 86

The following errors are at the bottom of the page.

Warning: Unknown: open(/home/content/10/12114910/tmp/sess_trmok9fgtb527mjp21a76shf54, O_RDWR) failed: No such file or directory (2) in Unknown on line 0

Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct () in Unknown on line 0

Once again, this is only a GoDaddy issue. My client was originally on Windows hosting and this just did not even work at all and I switched them to Linux hosting.

They were on PHP version 5.3 and I changed it to 5.4 and I have still had no luck.

I have never messed with a php.ini file. Would I need to create one? I have heard that uploading it into the public_html folder overrides the one on the server even though we are on a shared hosting plan.

Would I also need SSH access to create a tmp folder and set proper permissions for it?

This is usually quite easy to fix on crappy providers (I don't recommend GoDaddy, by the way).

Here is how I'd go about fixing it, hopefully it will help you.

Step 1: Make a directory and call it _sessions or something of that nature.

Step 2: Give it a chmod of 775 so that the web server can write to it.

Step 3: On the first script that runs, right at the top place session_save_path("./_sessions");

Step 4 (optional, but recommended): Add either deny from all in a .htaccess file to prevent people from getting to the directory, or simply chmod 776.
