Started Session C1 Of User

My System is Fedora 23 x86_64 running Xfce4
When system installed , i did:
and remove something i don't like with:
and shutdown (i don't recall if there is the bug appeared) but when i installed mariadb (or mysql) and postgresql and other things and shutdown there is always
Forums say it's a systemd bug but on systemctl command:
For me it worked simply by removing sessionstart, if the session is already started then why do we need to start it again.In my case It was just a config.php file which INCLUDEd in code – Mangesh Sathe Jun 25 '18 at 12:28. A user-designated name for the business process that initiated the Sterling Connect:Direct Server Begin Session service. If not specified, the process name is generated dynamically.
shows following info:
I don't thing it's mariadb or postgresql problem .
When shutdown, it only shows
not saying what job.
How can i debug this nasty bug ?
What tools or information do i need?

It seems like a bug. It affect me too. First time I've seen this bug on Fedora 20 or 21. It was patched, but returned in 23. It's somehow related to systemd and it's not only on Fedora - I've seen posts about it ex. on Arch Linux forums.
You can share with this, describing problems in this bug on bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1088619 or https://bugzilla.redhat.com/show_bug.cgi?id=1272635

I have a PHP file that is sometimes called from a page that has started a session and sometimes from a page that doesn't have session started. Therefore when I have session_start() on this script I sometimes get the error message for 'session already started'. For that I've put these lines:
but this time I got this warning message:
Notice: Undefined variable: _SESSION
Is there a better way to check if session has already started?
If I use @session_start will it make things work properly and just shut up the warnings?

Recommended way for versions of PHP >= 5.4.0 , PHP 7
Reference: http://www.php.net/manual/en/function.session-status.php
For versions of PHP < 5.4.0
lovelyramoslovelyramosFor versions of PHP prior to PHP 5.4.0:
Though, IMHO, you should really think about refactoring your session management code if you don't know whether or not a session is started..
That said, my opinion is subjective, and there are situations (examples of which are described in the comments below) where it may not be possible to know if the session is started.
AlexAlexPHP 5.4 introduced session_status(), which is more reliable than relying on session_id().
Consider the following snippet:
So, to check whether a session is started, the recommended way in PHP 5.4 is now:
BenjaminBenjaminyou can do this, and it's really easy.
Hope it helps :)
Prior to PHP 5.4 there is no reliable way of knowing other than setting a global flag.
Consider:
Or:
So, prior to PHP 5.4 you should set a global boolean.

Use session_id(), it returns an empty string if not set. It's more reliable than checking the $_COOKIE.
This should work for all PHP versions. It determines the PHP version, then checks to see if the session is started based on the PHP version. Then if the session is not started it starts it.
Dustin PoissantDustin PoissantNot sure about efficiency of such solution, but this is from working projectThis is also used if you need to define the default language
You should reorganize your code so that you call session_start() exactly once per page execution.
On PHP 5.3 this works for me:
then you have. If you do not put the not at if statement beginning the session will start any way I do not why.
Response BASED on @Meliza Ramos Response(see first response) and http://php.net/manual/en/function.phpversion.php ,
ACTIONS:
- define PHP_VERSION_ID if not exist
- define function to check version based on PHP_VERSION_ID
- define function to openSession() secure
only use openSession()
Pretty much I can't do anything but linger here in startup repair land. This may be useful to read - 'Startup Repair' on Win7 - how long does it take?

Actually, it is now too late to explain it here anyway as its been solved.This was a .inc file of one of my projects where you configure a menu for a restaurant by selecting a dish and remove/add or change the order.The server I was working at did not had the actual version so I made it more flexible. It's up to the authors wish to use and try it out.
PHP_VERSION_ID is available as of PHP 5.2.7, so check this first and if necessary , create it. session_status is available as of PHP 5.4 , so we have to check this too:
Based on my practice, before accessing the $_SESSION[] you need to call session_start every time to use the script. See the link below for manual.
For me at least session_start is confusing as a name. A session_load can be more clear.

You can use the following solution to check if a PHP session has already started:
Grant MillerThis is what I use to determine if a session has started. By using empty and isset as follows:
Suit Boy Apps@ before a function call suppresses any errors that may be reported during the function call.
Adding a @ before session_start tells PHP to avoid printing error messages.
Started Session C1 Of User Manual
For example:
Using session_start() after you've already printed something to the browser results in an error so PHP will display something like 'headers cannot be sent: started at (line 12)', @session_start() will still fail in this case, but the error message is not printed on screen.
Before including the files or redirecting to new page use the exit() function, otherwise it will give an error.
This code can be used in all cases:
