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.
As already stated by other, there is a chance that
Either the C:\temp\phpsessions directory doesn't exist,Or
Else IIS_IUSRS Read/Write Permission is missing in C:\Windows\Temp
there is no problem with your browser.
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.
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");
Most probably it is browser problem. Some mistmatch between browser and session data.
Just in case please do the following:
1. Clear the cache, cookies and temp data of your browser (or use another browser for experimental purposes).
2. Clear the directory where session files are stored on serverside (in your case it seems it is C:\Windows\TEMP or C:\temp\phpsessions. Better clean both of them).
If it does not work please share your php.ini file.
I'm having trouble with session variable in my setup. I'm storing some data in SESSION variables, but it seems like they're not stored properly, or at least I can't access them. On my local computr running MAMP it works ifne but in prod with php5/nginx, my session variables aren't stored. (I get an undefined index error).
I've read it can be related to the session.save_path and access rights, but I'm still confused. Where is this path defined? In my php.ini file there is this
;session.save_path = "/var/lib/php5"
But it starts with a ';' so I'm guessing it's ignored?
Also, what access should I give to the folder (once I've found it)? How can I know which user php is, and which group it belongs to? Seems like really basic stuff but I'm struggling to grasp it u__u
EDIT:
Apparently it's not a problem of permissions, since there are a lot of session folders in the directory, all created by php... So I really can't figure out why my session variables aren't accessible! :-(
It says undefined index...
Thanks in advance!

It is indeed ignored if it starts with ;. The default value is the temp directory, i.e. /tmp, but just to be sure, I suggest that you look in your phpinfo() and check it there because the file you checked might not be the only configuration your PHP uses.
The sessions path needs to be writable by PHP and it also has to be permitted by the open_basedir directive (if you use open_basedir which is highly recommended).
You use nginx so I'll assume you're using PHP-FPM. To find the PHP-FPM's user, you need to either find the user = ... directive in your php-fpm.conf (usually somewhere under /etc), or you can just find the running process using a tool like ps, htop, etc.
Hi there I want to update Path environmental variable permanently through PHP script. I know about putenv() but it is not permanent. I have read some where of generating a .reg file with following content.
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]
'PATH'='c:/abc/test/ImageMagick-6.7.8-Q8/convert.exe'
I have generated the file with content.
When I run this file, it shows me that file has been run successfully and key values containing in file is added in registry successfully. But When I go to path variable to check, my values are not there :-(
Can any body tell me why is this happening. I am using window 7. But my work has also to be compatible with window xp. Or is there any other way to accomplish this task?
Need suggestions....
Best Regards
The PATH environment variable in the registry is copied to a process' environment when the process is created.
cmd.exe (the command window or shell) is a process in it's own right. You have to SET PATH= within the shell to change it.
If you open a new command window, you should have the new PATH set. See also Programmatically adding a directory to Windows PATH environment variable
Hi I have solved this issue. I have solved it by creating .bat file. The content of .bat file looks like
#echo off
set KeyName=Path
set KeyValue="D:\songs;%PATH%"
setx -m %KeyName% %KeyValue%
-m is used if you want to set it at system level for all users. If you want it to set only for current user, then remove -m. The above command will set D:\songs in environement Path variable. To run this you need to be the administrator of the system.
Cheers if this is useful for any one :-)
I'm seeing an old path showing up on phpinfo under PATH. I've looked EVERYWHERE for it. Cannot figure out what's setting that path...
Checked php.ini, the apache conf files, there's no .htaccess, nothing in the index.php. Unless the old path is cached somehow somewhere, I cannot figure out where it's coming from.
I'm using Zend Server CE on Max OSX Leopard.
Did I overlook something? Any other place I should check for path being set?
UPDATE:
I rebooted the machine figuring that might remove the phantom path, and it did!
Wonder if this helps?
See: $PATH environment variable for apache2 on mac
Talks about checking /System/Library/LaunchDaemons/org.apache.httpd.plist
PATH can be set by a variety of files. For example, on Linux (and I would imagine mac which is also BSD) it is set by the init proc on startup. Apache may never overwrite this path, so it might just be using the default startup path set by init or your default user profile. You can probably overwrite it for apache if necessary with /System/Library/LaunchDaemons/org.apache.httpd.plist, or wherever apache is installed to.
As an example, when you run php --info as another user, what is PATH set to?
PATH is an environmental variable and does not have anything to do with PHP or Apache.
Here is an article: http://mactip.blogspot.com/2004/04/setting-environment-variables.html
when I uploaded the script to the server I got this error
Warning: Unknown: open(/tmp/sess_58f54ee6a828f04116c2ed97664497b2, O_RDWR) failed: Permission denied (13) 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 (/tmp) in Unknown on line 0
The error appeared when I call session_start(), although I set the permission of /tmp folder to 777.
Change session path where you can write data or contact server administrator about /tmp problem
http://php.net/manual/en/function.session-save-path.php
you will need to change your session.save_path php.ini directive
You can do that using session_save_path
If you have SSH access, here is how to correct the permission and ownership
sudo chown -R NAME_OF_USER /tmp
Replace NAME_OF_USER by the user under which runs php. You can find it by simply putting these lines in a php file:
$processUser = posix_getpwuid(posix_geteuid());
print $processUser['name'];
exit;
Check that you're not running into diskspace issues. If all the permissions are correct (and 777 ought to do it for you), then you might still get this error (for some versions of PHP and Apache) if there isn't enough space to write to the disk.
I had this problem in the following situation:
I filled some session vars with PHP
While the session was still active, I changed from PHP 5.4 to 5.3 on my host.
Reloading the page gave the error, described above.
Reset the PHP version to 5.4 again.
Used session_unset(); and session_destroy(); to clean the current session.
Changed the PHP version back to 5.3.
Now it works again.
Conclusion: For an irrelevant reason I had to change my PHP version, and while switching with sessions alive, the sessions get corrupted.
I realize that this is an old post, however I just ran into this problem, and found an easy solution.
For me, the issue was happening with one of my websites deployed locally. I hadn't tried accessing the websites using other browsers, but it was happening every time I tried to access this site via Chrome. I decided to go into the Chrome developer tools, under the application tab -- and clicking "Clear Storage". Voila -- everything is working like magic again.
Hope this helps someone else!
Additionally, you may want to use ini_set('session.save_path', '/dir/here'); assuming you have access to this function. The other ways suggested are valid.
I've just had exactly the same problem with one of my PHP scripts and I was like what did I break 'cos it worked perfectly the day before and I'm running it from my own local Puppy Linux machine so it's not even a host or anything.
The only thing I'd been doing before that was trying to get Java to work in the web browser, so some how I'd managed to get Java to work but broke PHP - oops!
Anyway I did remember that whilst trying to get Java to work I had deleted the contents of the /tmp folder to wipe anything out that may be causing a problem (it actually turned out with Java I was using the old plugin oij with the new Firefox)
To solve this problem I opened up Rox File Manager, went to the / folder and right clicked on the tmp folder -> Mount Point 'tmp' and clicked properties.
I noticed the permissions were set as Owner - Read, Write, Exec, but Group and World were only set at Read and Exec and not Write. I put a tick in Write for both Group and World and now PHP works fine again.
I don't know at what point the permissions for tmp must have changed but for PHP to use them it must be set to have Write permissions.
Add following line
ini_set('session.save_path', getcwd() . '/tmp');
before
session_start();
if you are using Apache web server, the quick fix is to go to your command line and type:
open /etc/apache2/
then from the window opened, open the file called httpd.conf and search for User or Group change these 2 lines to:
User _www
Group _www
This is because you want your server to have permission to your systems directories, especially you want to change the User or you can leave your Group to either staff or admin.
I had the same problem of permission, but on /var/lib/php/session/.
To fix it, I deleted the file and restarted php-fpm.
rm -rf /var/lib/php/session/sess_p930fh0ejjkeeiaes3l4395q96
sudo service php5.6-fpm restart
Now all works well.
For me the problem seems to be a WHM bug!
I have a bunch of add on domains and all work fine but with a subdomain it brings this error.
Strange thing but if I use the full URL with the main domain it works fine:
main-domain.com/my.subdomain.com
If I use the subdomain directly it brings "Permission denied (13)":
my.subdomain.com
The thing is all addon domains root is:
/home/xx/
But for my subdomain, don't know why, the root is: (I shouldn't have access to that dir)
/
So it´s really trying to reach: /tmp instead of /home/xx/tmp
Which also exists but don't have the right permissions
To clarify this are examples of the whole path:
/home/my-account/public_html
/home/my-account/tmp
/tmp
The workaround I used was:
session_save_path('/home/my-account/tmp');
session_start();
Using PHP 5.6 I had already used session_save_path() to point to a directory within the domain's structure. It worked fine until I upgraded to PHP 7.0, at which time I received the noted error. At PHP.net I found several comments that indicated assigning a direct path didn't always work, so I used their suggestion.
session_save_path(realpath(dirname($_SERVER['DOCUMENT_ROOT']) . '/../session'));
worked perfectly. Remember to change /../session to the relative location of your actual session directory.
If :
session.gc_probability > 0
session files are created by different user(s) (e.g. root and apache).
session files are all stored in the same place (e.g. /var/lib/php/session)
Then you'll see this error when e.g. the Apache PHP process attempts to run garbage collection on the session files.
Fixes :
Reconfigure PHP so gc_probability is 0, and have a cron job removing the old/stale file(s).
Have each different user save their session files in separate place(s) (session_save_path() etc).
I initially had this issue due to nginx owning the /tmp location and php-fpm was running under 'apache' user and group due to the www.conf. I swapped out the user/group in that file and then it worked ok. You may want to check <?php echo exec('whoami'); ?> to verify.
In my case the problem was SELINUX not allowing this.
A helpful command to get suggestions on how to fix this:
sealert -a /var/log/audit/audit.log
If you want to rule out SELINUX, try disabling it for a moment. If that fixes the issue then that is the problem.
