PHP session warning in Windows IIS

Question

Error during session start; please check your PHP and/or webserver log file and configure your PHP installation properly. Also ensure that cookies are enabled in your browser.

session_start(): open(C:\Windows\TEMP\sess_3ls3qdk77m9mhsf5tm1cdhrm05bi5kb1, O_RDWR) failed: Invalid argument (22)

in my php.ini file: session.save_path = "C:\temp\phpsessions" Before it was working fine. So sudden it is showing an error. anyone can assist with this please.

Answer 1

As already stated by other, there is a chance that

1. Either the C:\temp\phpsessions directory doesn't exist,Or
2. Else IIS_IUSRS Read/Write Permission is missing in C:\Windows\Temp

there is no problem with your browser.

Answer 2

Double check the permissions on C:\Windows\Temp\ folder. I think IIS_IUSRS needs to have write access in order for files to be saved.

Consider moving the session folder out of C:\Windows\

Where ever you put the sessions, iis will need permissions to edit it.

Answer 3

PHP will not create this directory structure automatically. So make sure this C:\temp\phpsessions directory exist. If not, then you can use the script in the ext/session dir for that purpose or create that directory structure manually.

and then

You can change session save path by writing this line for created directory before session start also note here extra '\' because of escape character.

session_save_path("C:\\temp\\phpsessions");
