How can I switch to a previously saved session using Zend\Session\SessionManager? I know the session ID.
For example, this doesn't work:
$sm->start();
$sm->setId('abc');
$_SESSION will not contain the data of session 'abc'. Calling $sm->writeClose() after $sm->start() doesn't help either.
I can easily do this using standard PHP functions:
session_start();
session_write_close();
session_id('abc');
session_start();
//$_SESSION is populated with 'abc' data.
Zend uses session namespaces for that. If you give the session a name like this
$sess = new Zend_Session_Namespace('abc');
you can access the contents via $sess->var and reload the session in a different PHP file just by creating the new session with the same name again.

I have a page that creates different sessions depending on different users it renames the session file to fit that user
session_name("name");
session_start();
//i then put in a variable in the session file
$sn=$_POST["name"];
$_SESSION['name'] = $sn;
now in another file I want to access the session with the session name I just created
session_start();
echo $_SESSION['name'];
but it just creates a new session file and says undefined variable $_SESSION['name'].
Please see the following
Using session_name() in PHP - Cannot Access Data
TLDR: At each startup request time (as already mentioned) the session will be renamed to PHPSESSID unless you call session_name( 'fObj') before session_start() on every page
I have a PHP script that uses session_decode to get the session variables of customer's session (from session stored file).
The problem is that whenever I call the script and it reads the session variables, it also add them to my own session. Is there a way to avoid this or maybe use a better method to get the customer's session information without using session_decode?
Thanks
I think I have found the simplest solution/workaround:
<?php
// if session is not started
session_start();
// store our current session
$my_sess = $_SESSION;
// decode $data (the encoded session data, either from a file or database). Remember, decoded data is put directly into $_SESSION
session_decode($data);
$data = $_SESSION;
print_r($data);
// restore our own session
$_SESSION = $my_sess;
?>
Newbie question, but I'm wondering if I'm missing something elementary here.
If I register a session variable in a page - isn't this variable supposed to be accessible from another page on the same site?
First, I register a variable in the file session_var_register.php:
<?php
$_SESSION["myusername"] = 'user';
if (isset($_SESSION['myusername'])) {
echo 'Session var myusername is set to '.$_SESSION['myusername'];
}
?>
When I open this page, it writes:
Session var myusername is set to user
As expected.
Then I open another tab and another page, check_session_var.php:
<?php
if (isset($_SESSION['myusername'])) {
echo 'Session var myusername is set to '.$_SESSION['myusername'];
}
?>
This page is blank.
Isn't the point of a session variable that it should be accessible in the browser session, until the session is programatically destroyed or the browser closed?
I'm using IE 8 and Firefox 24, btw. Identical results.
You forgot
session_start()
On top, before using
$_SESSION
PS: Remember to call session_start() in every page you want to use $_SESSION.
The PHP docs state that you must call session_start() to start or resume a PHP session. This must be done before you try to access or use session variables. Read more here.
session_start();
Your session variables will be available on different pages of the same site but on top of each of these pages you must have at least:
session_start();
It works but not in all cases. You must also use the same session name (essentially a cookie name that stores id of your session) on all pages. Moreover cookies (which are essential (mostly) for sessions to work) may be made visible only in specific directory. So if for example you share the same host with other guys that use sessions too you do not want to see their variables and vice versa so you may want to have sth like that:
1) session_name( 'my_session_id' );
2) session_set_cookie_params( 0, '/my_dir', $_SERVER['HTTP_HOST'], false, true );
3) session_start();
You may also want to see your session variables on other servers and in such case custom session handlers may be useful. Take a day or two to implement yourself - great way to understand how sessions work hence I recommend.
Method
session_start();
Description
session_start() creates a session or resumes the current one based on a session identifier >passed via a GET or POST request, or passed via a cookie.
Usage in your case (and in the most of cases):
Put it before the $_SESSION usage.
Reference: session_start()
First Of all start session on that page
session_start();
your page like this way
<?php
session_start();
if (isset($_SESSION['myusername'])) {
echo 'Session var myusername is set to '.$_SESSION['myusername'];
}
?>
I installed a pre-built forum on my website and I want (in a diffrent page) to check if the forum's session is active.
Something like :
if (isset($_SESSION['forum'])) { echo "Session is active!"; }
Problem is - I don't know the sessions name...
Tried downloading some chrome add-ons for session managing but I can't get the name of the session.
Whats the right way of doing this?
Thanks ahead!
You can see the dump of $_SESSION variable
var_dump($_SESSION);
session_name() will give you the session name, that usually is defined in php.ini. By default it is always: PHPSESSID. This name is used as cookie name or as POST/GET variable name.
session_id() will give you the identifier for the current session. It will be the contents of the cookie or POST/GET variable.
Then you have $_SESSION that will contain all your session data. use print_r() to see what you have stored in it so far.
To know if session vars are set you can also just do if(isset($_SESSION)&&count($_SESSION))
try
print_r ($_SESSION);
taht way you'll see all sessions
<?php
session_start();
print_r($_SESSION);
?>
Use this to see which session variables are currently set.
You need to check that the session is currently active, and then that the forum key is defined
if ( ! ($sid = session_id()) {
session_start(); // open session if not yet opened
$sid = session_id(); // get sid as session ID
}
// $sid contains the session ID (in cookie)
if (isset($_SESSION['forum'])) {
// forum is defined
}

I am passing my session ID thru a flash file to a php file and I am capturing the session ID on the other side and replace the newly generated ID by the old one.
$SID = $_GET['mysession'];
session_id($SID);
session_start();
Unfortunately the session is now empty and I don't get why.
print_r($_SESSION);
returns just a 1. All variables from the session are empty/do not exists.
Anyone an idea how to catch the data again?
PHP Version 5.2.6-1+lenny12 with Apache.
Thanks
David
I think you need to use session_start(); before you set anything in the session.
use it like this,
session_start();
$SID = $_GET['mysession'];
session_id($SID);
This says, enable session handling on this page and starts a session. after that you are fetching your previous session id and then assigning the same session id to this session.
Hope, it helps you.
