Story & origin
Simple Session – 21 years of mad action!
Simple Session’s international activities introducing Tallinn and Estonia as an attractive tourism destination of action sports and culture are supported by The European Regional Development Fund (200 000 euros for three events 2020-2022).
Simple Session 21 will be back in Tallinn, Estonia, on August 20–21 with a big summertime festival and an all-around good time! The Simple Session series will host an exciting street-focused contest in the hip new Põhjala district – an old rubber factory turned into a cultural hub will serve as a thrilling new location for the event. Simple Session 21 will also be one of the first more significant international events after the big Olympic debut in Tokyo – so much extra hype around our sports.
Sixty-four of the finest invitation-only BMX street riders and skateboarders from around the world will go head to head on a new 600m2 Wessel-designed street course.
Skateboarding and BMX are all about creativity. So is Simple Session – hosting the series at the coolest and liveliest venue in Tallinn will take the entire contest experience to another level for athletes and viewers alike. We are coming closer to fans and back to the core of these sports as well to our roots. The global health crisis has created obstacles and prevented us from hosting the annual wintertime event. On the sunny side, it prompted us to regroup and innovate the series, and we are delighted with the result.
The event celebrates the Estonian Restoration of Independence on the 20th of August, kicking off a long weekend of the best riding and Simple Session antics on and off the course. We are incredibly excited to host riders in the stunning Estonian summer after most athletes have experienced Estonia only in the cold winter months. It’s been 12 years since Tallinn last hosted a Simple Session summertime edition – that’s about to change.
Simple Session 21 also features its (in)famous three-day party & after/hours program from Thursday to Saturday 19–21.08.

session_start
(PHP 4, PHP 5, PHP 7, PHP 8)
session_start — Стартует новую сессию, либо возобновляет существующую
Описание
Функция session_start() создаёт сессию, либо возобновляет существующую, основываясь на идентификаторе сессии, переданном через GET- или POST-запрос, либо переданный через cookie.
Если разрешена опция session.use_trans_sid, функция session_start() регистрирует внутренний обработчик вывода для перезаписи URL.
Список параметров
Возвращаемые значения
Список изменений
Примеры
Простой пример сессии
Пример #1 page1.php
echo ‘Добро пожаловать на страницу 1’ ;
$_SESSION [ ‘favcolor’ ] = ‘green’ ;
$_SESSION [ ‘animal’ ] = ‘cat’ ;
$_SESSION [ ‘time’ ] = time ();
// Работает, если сессионная cookie принята
echo ‘
page 2′ ;
Пример #2 page2.php
echo ‘Добро пожаловать на страницу 2
‘ ;
// Можете тут использовать идентификатор сессии, как в page1.php
echo ‘
page 1′ ;
?>
Передача опций в session_start()
Пример #3 Переопределение времени жизни cookie
Пример #4 Чтение и закрытие сессии
Примечания
Для использования сессий на основе cookie, функция session_start() должна быть вызвана перед выводом чего бы то ни было в браузер.
Эта функция отсылает несколько заголовков HTTP, в зависимости от настроек. Смотрите описание функции session_cache_limiter() для управления этими заголовками.

If you want to handle sessions with a class, I wrote this little class:
/*
Use the static method getInstance to get the object.
*/
class Session
<
const SESSION_STARTED = TRUE ;
const SESSION_NOT_STARTED = FALSE ;
private function __construct () <>
/**
* Returns THE instance of ‘Session’.
* The session is automatically initialized if it wasn’t.
*
* @return object
**/
/**
* (Re)starts the session.
*
* @return bool TRUE if the session has been initialized, else FALSE.
**/
/**
* Destroys the current session.
*
* @return bool TRUE is session has been deleted, else FALSE.
**/
// We get the instance
$data = Session :: getInstance ();
// Let’s display datas
printf ( ‘

As others have noted, PHP’s session handler is blocking. When one of your scripts calls session_start(), any other script that also calls session_start() with the same session ID will sleep until the first script closes the session.
A common workaround to this is call session_start() and session_write_close() each time you want to update the session.
The problem with this, is that each time you call session_start(), PHP prints a duplicate copy of the session cookie to the HTTP response header. Do this enough times (as you might do in a long-running script), and the response header can get so large that it causes web servers & browsers to crash or reject your response as malformed.
This error has been reported to PHP HQ, but they’ve marked it «Won’t fix» because they say you’re not supposed to open and close the session during a single script like this. https://bugs.php.net/bug.php?id=31455
As a workaround, I’ve written a function that uses headers_list() and header_remove() to clear out the duplicate cookies. It’s interesting to note that even on requests when PHP sends duplicate session cookies, headers_list() still only lists one copy of the session cookie. Nonetheless, calling header_remove() removes all the duplicate copies.
/**
* Every time you call session_start(), PHP adds another
* identical session cookie to the response header. Do this
* enough times, and your response header becomes big enough
* to choke the web server.
*
* This method clears out the duplicate session cookies. You can
* call it after each time you’ve called session_start(), or call it
* just before you send your headers.
*/
function clear_duplicate_cookies () <
// If headers have already been sent, there’s nothing we can do
if ( headers_sent ()) <
return;
>
The constant SID would always be » (an empty string) if directive session.use_trans_sid in php ini file is set to 0.
So remember to set session.use_trans_sid to 1 and restart your server before you use SID in your php script.
As of this writing, it seems to be happening in PHP 7.1, and things look OK in PHP7.0.
The fix is simple. you just need to check for ‘null’ during your read function:
PHP locks the session file until it is closed. If you have 2 scripts using the same session (i.e. from the same user) then the 2nd script will not finish its call to session_start() until the first script finishes execution.
If you have scripts that run for more than a second and users may be making more than 1 request at a time then it is worth calling session_write_close() as soon as you’ve finished writing session data.
// a lock is places on the session, so other scripts will have to wait
session_start ();
I recently made an interesting observation:
It seems that `session_start()` can return `true` even if the session was not properly created. In my case, the disk storage was full and so the session data could not be written to disk. I had some logic that resulted in an infinite loop when the session was not written to disk.
To check if the session really was saved to disk I used:
«`
function safe_session_start () <
# Attempt to start a session
if (!@\ session_start ()) return false ;
# Attempt to write session to disk
@\ session_write_close ();
# Re-start session
@\ session_start ();
if (! safe_session_start ()) <
# Sessions are probably not written to disk.
# Handle error accordingly.
>
Took me quite a while to figure this out.
Maybe it helps someone!
PHP Manual specifically denotes this common mistake:
See session_id() manual page for more details.
If you store a session var while on the CNAME:
vanity.example.com and the hostname of the server is hosname.example.com
Then try to call the variable from a different page, it will not find it because of the CNAME (I guess it store the variable under the hostname, then when trying to read it it’s still looking under the CNAME) the same application works fine when accessing it under the hostname directly. Keep in mind that I was testing this on an internal network.
The following code shows how the PHP session works. The function my_session_start() does almost the same thing as session_start().
When you have an import script that takes long to execute, the browser seem to lock up and you cannot access the website anymore. this is because a request is reading and locking the session file to prevent corruption.
you can either
— use a different session handler with session_set_save_handler()
— use session_write_close() in the import script as soon you don’t need session anymore (best moment is just before the long during part takes place), you can session_start when ever you want and as many times you like if your import script requires session variables changed.
A session created with session_start will only be available to pages within the directory tree of the page that first created it.
i.e. If the page that first creates the session is /dir1/dir2/index.php and the user then goes to any page above dir2 (e.g. /dir1/index.php), session_start will create a new session rather than use the existing one.

Hope this helps someone with their sessions.
Thanks.
If you ever need to open multiple distinct sessions in the same script and still let PHP generate session ids for you, here is a simple function I came up with (PHP default session handler is assumed):
Note: it’s probably rarely a good idea to handle multiple sessions so think again if you think you have a good use for it.
Personally it played its role for some quick patching of legacy code I had to maintain.
Initiating a session may overwrite your own custom cache control header, which may break clicking back to get back to a prior post request (on Chrome at least).
On my system it was setting ‘no-store’, which is much more severe than ‘no-cache’ and what was breaking the back-button.
If you are controlling your own cache headers carefully you need to call:
session_cache_limiter(»);
. to stop it changing your cache control headers.
To avoid the notice commited by PHP since 4.3.3 when you start a session twice, check session_id() first:
if (session_id() == «»)
session_start();
I just need with easy, count how many times the page reload over the site, may to add a warning popup, while the counter is 0:
A note about session_start(), custom handlers and database foreign key constraints, which I think may be of some use.
We know that if we want our sessions into a database table (rather than the default storage), we can refer to session_set_save_handler(. ) to get them there. Note that session_set_save_handler must (obviously) be called before session_start(), but let me get to the point.
Upon calling session_start() the «first time», when the session does not already exist, php will spawn a new session but will not call the write handler until script execution finishes.
Thus, the session at this point exists in the server process memory, but won’t be visible as a row in the DB before the script ends.
This seems reasonable, because this avoids some unnecessary database access and resource usage before we even populate our session with meaningfull and definitive data, but this also has side-effects.
In my case, the script called session_start() to make sure a session was initiated, then used session_id() to populate another table in the DB, which had foreign_key constraint to the «sessions» table. This failed because no session was in the db at that point, yet!
I know I could simply force the creation of the row in the DB by manually calling the write handler after session_start(), when necessary, but I am not sure if this is the best possible approach.
As soon as I find an «elegant» solution, or a completely different approach, I will post some working sample code.
In the meanwhile. have fun!
Websites are prone to Session Attack where its proper usage is not done.
There are tools like «Apache Benchmark» (ab) and many others which can hit the website with load for load / performance testing.
Code below starts the session for every request.
$_SESSION [ ‘user_id’ ] = Suserdetails [ ‘user_id’ ];
$_SESSION [ ‘username’ ] = Suserdetails [ ‘username’ ];
$_SESSION [ ‘firstname’ ] = Suserdetails [ ‘firstname’ ];
header ( ‘Location: dashboard.php’ );
>
?>
This generates session file for every request irrespective of PHPSESSID cookie value when I use tools like ab, there by creating inode issue.
One should start the session after properly authenticating.
$_SESSION [ ‘user_id’ ] = Suserdetails [ ‘user_id’ ];
$_SESSION [ ‘username’ ] = Suserdetails [ ‘username’ ];
$_SESSION [ ‘firstname’ ] = Suserdetails [ ‘firstname’ ];
header ( ‘Location: dashboard.php’ );
>
?>
Scripts other then login first validates session which requires session.
if( session_status ()!= PHP_SESSION_NONE ) header ( ‘Location: login.php’ );
If you open a popup window (please no commercial ones!) with javascript window.open it might happen IE blocks the session cookie.
A simple fix for that is opening the new window with the session ID in a GET value. Note I don’t use SID for this, because it will not allways be available.
A simple session_start() will not be sufficiant to kepp you Session alive.
Due to the filesystems mounting parameters, atime will normally not be updated. Instead of atime, mtime will be delivered.
This behavior may cause an early session death and your users my be kicked of your login system.
To keep the session alive it will be necessary to write something into the sessionfile at each request, e. g. a simple
That would keep your session alive, even if the client in reality is only clicking around the site.
Be warned that depending on end of script to close the session will effectively serialize concurrent session requests. Concurrent background «data retrieval» (e.g. applications such as AJAX or amfphp/Flex) expecting to retrieve data in parallel can fall into this trap easily.
Holding the session_write_close until after an expensive operation is likewise problematic.
To minimize effects, call session_write_close (aka session_commit) as early as practical (e.g. without introducing race conditions) or otherwise avoid the serialization bottleneck.
James at skinsupport dot com raises a good point (warning) about additional requests from the browser. The request for favicon.ico, depending on how it is handled, can have unintended results on your sessions.
For example, suppose you have ErrorDocument 404 /signin.php, no favicon.ico file and all pages in your site where the user signs in are also redirected to /signin.php if they’re not already signed in.
If signin.php does any clean up or reassigning of session_id (as all good signin.php pages should) then the additional request from the browser for favicon.ico could potentially corrupt the session as set by the actual request.
Kudos to James for pointing it out and shame on me for skimming past it and not seeing how it applied to my problem. Thanks too to the Firefox Live HTTP Headers extension for showing the additional request.
Don’t waste days or even hours on this if your session cookies are not being sent or if the session data isn’t what you expect it to be. At a minimum, eliminate this case and see if any additional requests could be at fault.
A handy script that checks fot the presence of uft-8 byte order mark (BOM) in all files in all directories starting on current dir. Combined from the work of other people here.
For those of you running in problems with UTF-8 encoded files:
I was getting an error because of the BOM, although i set Dreamweaver to «save as» the without the BOM. It appears that DW will not change this setting in already existing files. After creating a new file withou the BOM, everything worked well.
I am trying to get a session created by a browser call to be used by a command line cli->curl php call (in this case, both calls to the same server and php.ini), for a set of flexible media import routines,
but the cli->curl call always starts a new session despite me putting PHPSESSID=validID as the first parameter for the url called by curl.
I was able to fix it by calling session_id($_GET[‘PHPSESSID’]) before calling session_start() in the script called via curl.
