session_write_close -- Write session data and end session

Description

Surfshark vpn apk download. Description void sessionwriteclose ( void ). End the current session and store session data. Session data is usually stored after your script terminated without the need to call sessionwriteclose, but as session data is locked to prevent concurrent writes only one script may operate on a session at any time.When using framesets together with sessions you will experience the frames. I was perplexed by inconsistent results with the session ID depending on whether I retrieve it using SID, COOKIE, or sessionid. I have found that sessionid is the most reliable method, whereas SID and COOKIE'PHPSESSIONID' are sometimes undefined.

End the current session and store session data.

Session data is usually stored after your script terminated without the need to call session_write_close(), but as session data is locked to prevent concurrent writes only one script may operate on a session at any time. When using framesets together with sessions you will experience the frames loading one by one due to this locking. You can reduce the time needed to load all the frames by ending the session as soon as all changes to session variables are done.

Maybe depending on PHP settings, but if return values are not the above, then go for this:
_DISABLED = 0
_NONE = 1
_ACTIVE = 2

Universal function for checking session status.
<?php
/**
* @return bool
*/
function is_session_started()
{
if (
php_sapi_name() ! 'cli' ) {
if (
version_compare(phpversion(), '5.4.0', '>=') ) {
return
session_status() PHP_SESSION_ACTIVE ? TRUE : FALSE;
} else {
return
session_id() ' ? FALSE : TRUE;
}
}
return
FALSE;
}
// Example
if ( is_session_started() FALSE ) session_start();
?>

Use always session_status(), to check if a session is already started and active.
if(session_status() ! PHP_SESSION_ACTIVE) session_start();
or
if(session_status() PHP_SESSION_NONE) session_start();
Don't use
if(!isset($_SESSION)) session_start();
or
if(session_id() ') session_start();
They will not work properly after a call to session_write_close().
Both functions will continue to report, that the session exists.
And this is right, you can read from $_SESSION, but if you want to write,
you need session_start() again.
As a shorthand you can use
@session_start()
with the @ at the beginning to suppress the
PHP notice 'A session had already been started - ignoring session_start()'
As stated in the manual for session_start(), a second call will do no harm,
it will be simply ignored. But you need the @, if you don't want to get the notice.

The advice of ive_insomnia at live dot com should be taken with great care.
First of all, while his use case for session_status is valid, a simpler way to avoid the warning is:
<?php
if (!isset($_SESSION)) { session_start(); }
?>

The example of session_status uses the raw values of constants (2 in this case) created specifically for the purpose of not having to use magic numbers.
Better code would be:
<?php
if (session_status() ! PHP_SESSION_ACTIVE) {session_start();}
?>

The same can be done using
<?
if (session_id() ') { session_start(); }
?>
The use of this function is lies more towards status management: change the behavior of a script when sessions are disabled altogether, for example.

This is how the session_status() works:
<?php
function session_status(){
if(!
extension_loaded('session')){
return
0;
}elseif(!
file_exists(session_save_path().'/sess_'.session_id()){
return
1;
}else{
return
2;
}
}
?>

Just another function to determine whether the session has already started:
function is_session_started () {
return function_exists ( 'session_status' ) ? ( PHP_SESSION_ACTIVE session_status () ) : ( ! empty ( session_id () ) );
}

If you started and closed a session then test ( session_id() ' ) to check if a session is active it won't work, session_id() returns an ID even if the session is closed.
Anybody knows another way before PHP 5.4 to check if a session is really not currently active ?

Here some Good example for your understandingl
<?php
if( session_status PHP_SESSION_NONE ) // if session status is none then start the session
{
session_start();
}
?>

old Practice we were using.
<?php
if( !( isset($_SESSION) ) ) // if the session is no set then start to
new session
{
session_start();
}
?>

Session_write_close Not Working

The purpose of this functionality can aid you specifically in cases where code -- prior to your current code -- might have opened a session and then closed it.
Specifically, depending on $_SESSION, session_id(), and the SID constant to determine if a session is active will FAIL if a session has previously been opened & closed within the same request cycle.
