unset?
unset($_SESSION['order'][$reference]['quantity']);

Can't seem to reach php.net to confirm, but I use it myself ;)

Unset($_SESSION['order'][$reference]['quantity']); will clear the  
entire session object

Maybe I'm missing something, but why are you using session vars and
cookie vars like you are?  If you start a session it creates a cookie to
track the session and the session persists your session vars.  Why not
just use session vars?

I have this at the begining of the first file.

if (isset($_COOKIE['sale_cookie']) && isset($_COOKIE['assess_cookie'])) 
{

  $_SESSION['sale_value'] = $_COOKIE['sale_cookie'];
  $_SESSION['assess_value'] = $_COOKIE['assess_cookie'];
}

?>



I have tried this

echo $sale_value;
echo $_SESSION['assess_value'];
echo $_COOKIE['sale_cookie'];

I have also removed all of the if() and still not had success

None of which are producing results...

Anyone see where I am going wrong... I have spent all day online, in the

Looks to me like you are trying to set and retrieve a cookie on the same
page. It doesn't work that way. Set it, access it on the next page... 
or, set it, and then redirect to the same page.. being sure to send a 
flag to hide the setcookie function to avoid the dreaded infinite loop.


Also, Setting a cookie's expire param to history will delete it... so
I don't think that is what you want to do.

Make sure your file isn't a UTF-8 with DOM.

Re: [PHP] $_session/$_cookie trouble

[Andrew Hucks]

Take the values out of single quotes, else it sets them as strings,
and not as the variable value. Also, are you meaning to set the
cookie's expiration to time()-3600? Try time()+3600.

Re: [PHP] $_session/$_cookie trouble

[Gary]

Thanks again, dont see any DOM

As I mentioned I am no longer getting error message, but not sure it is 
working.

I have this at the begining of the first file.





I have tried this

echo $sale_value;
echo $_SESSION['assess_value'];
echo $_COOKIE['sale_cookie'];

I have also removed all of the if() and still not had success

None of which are producing results...

Anyone see where I am going wrong... I have spent all day online, in the 
books, in the manual...

Thanks again

gary

There it is then. The HTML file causes the headers to be sent. Any
output to the browser at all causes the headers to be sent, so any HTML
or even spaces and newlines will trigger this error.

Re: [PHP] $_session/$_cookie trouble

[Gary]

Ashley

There are 3 include files, the first is all html, but it has a form, so I 
put the session_start above the DTD and I no longer get the error messages.

I had the session_start at the beginning of the second file, the php 
processing file, but that produced the error.  It seemed to be calling to 
itself (if that does not sound too naive).

As I mentioned in a post above, I am no longer getting the error message, 
but have been unable to get either the $_SESSION or the cookie to produce 
results...

Thanks for your help.

Re: [PHP] $_session/$_cookie trouble

Igor

Thanks for the link.  It was suggested that I must put the session_start() 
before all code on the parent page.  I am no longer getting the error 
messages,so I am assuming I am making progress, however I have yet to be 
able to get the $_SESSION or $_COOKIE to produce results...such as the 
ability to echo them.

Thanks for your help.

The code is being pulled in from somewhere, have you checked to see if
the framework you are using is pulling it in?

Whatever it is on line 2 of assessresult.inc.php that is causing output
to be started!

More seriously, there is something on line 2 of that file that is
causing something to be sent to the browser, which in turn causes the
http headers to be sent. Once those headers have been sent, nothing else
that wants to send headers, which includes starting the session and
setting cookies, can be done.

Either eliminate whatever it is on line 2 that is sending output, or
move the session_start() and/or setcookie() calls above it. (This early
in the file, prime candidate is actually a stray blank line outside your

That's the CLI version, which is likely completely different from
your web version.  They're generally two separate binaries.

Send the actual code and we can take a look at it.  It's probably
something as simple as a typo.

This shows the php command line version, not the webserver php version.
To do that, look at a phpinfo() page. They may indeed be the same but
don't think that they always will be. I can run php4 for my webserver
version and php5 command line and vice-versa.

[PHP] $_SESSION lost

[hce]

Hi,

I've just installed PHP 5.2.4 on a FC 7 with a web server.

$ php -v
PHP 5.2.4 (cli) (built: Sep 18 2007 08:50:58)
Copyright (c) 1997-2007 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2007 Zend Technologies

It seems some PHP module might be missing, I tested it with a page1.php:

session_start();
$_SESSION['favcolor'] = 'green';

Then I click a link in page1.php to go another page2.php:

session_start();
echo "favcolr =" . $_SESSION['favcolor'];

It only displayed "favcolr =", it was empty in $_SESSION['favcolor'].
The test script page1.php and page2.php are working fine on other
machines.

I checked with php modules, the "session" is there.

What could I be missing in PHP modules or setup?

Thank you.

Hi!

Did you test with phpinfo() if the correct php.ini is used?

Re: [PHP] $_SESSION NOT WORKING

[Balpo]

Yes, that way it works. Thanx.
But the Windows version of the same code and the same php.ini ***does 
not *** need the session_start()

because it has the session.auto_start = 1 inside php.ini.

The thing is,  I think session.auto_start = 1 does not work on Linux.

Is this a bug?

Re: [PHP] $_SESSION v. Cookies

[Craige Leeder]

I can't see PHP sessions slowing down your site by that amount. As
someone said, it should be no more than a split second. If you are
having that much of a problem with them, then I would say it is either
your implementation, or another determining factor.

I would not, personally, stray away from PHP's GC of sessions. I would
imagine that any third-party concoction could not be any faster. I
would however, check to see how long PHP takes to clean up defunct
sessions, and also monitor how many sessions are lying around at any
given time.

that setting is the chance (in percents) for the stock gc to run at any
request. so if it is set to 0, it does not have a chance ;)
of course it will try but it always decides not to run

but wont it still try to run sometimes since that setting determines whether
or not the gc will run *every* time ?  i would imagine if it was for *any*
time, setting session.gc_probability = 0 would effectively disable the stock
gc.

Then do it yourself in a script called by cron.


it would be nice if you could latch into the one they provide out of the box

session.gc_probability = 0

 What clean-up?


All the inactive session files... inactive and garbage collection time
is denoted by the following php.ini settings:

session.gc_probability= 1 ; percentual probability that the
  ; 'garbage collection' process is

Oh, Okay. That's an automatic practice taken from the php.ini 
settings. I was thinking that maybe one was supposed to do something 
after using sessions.

so where is the setting, using the stock session handler, to relegate the gc

All the inactive session files... inactive and garbage collection time
is denoted by the following php.ini settings:

session.gc_probability= 1 ; percentual probability that the 
  ; 'garbage collection' process is
  ; started
  ; on every session initialization
session.gc_maxlifetime= 1440  ; after this number of seconds,

Did you add any includes and are they include or include_once or require VS. 
require_once?

I found stress tests that show that an include is faster then an include_once 
and so removing the _once from includes and requires will speed up your site.

How are your sessions implemented? Are you using the stock PHP session
functionality or did you cook your own solution? I can't see the stock
PHP solution adding anything more than a split second to your page time.
The exception being when it performs cleanup. Cleanup should be
relegated to a cron job. Have you added anything new to the database?
new query perhaps on a large table that doesn't make use of indexes?
Small changes can have a bigger impact than large changes depending on
what exactly changed.

Rob.

[PHP] $_SESSION v. Cookies

[Scott Campbell]

Dear PHP List,

PHP 5, Apache2, MySQL 5, running on Ubuntu, viewing & deving with
FireFox and Konqueror (Linux).

I am building a site with multiple tools and want to pass variables
throughout them all.  Before, I was passing variables using  HTML
Form tags, but the site has grown too large for this tactic, so I went to
using $_SESSION.  However, when I started using $_SESSION, my site loads 3-5
times slower then before.  A page that queried MySQL and built itself in 3-5
seconds was now taking 15-20.  While more has changed then just $_SESSION,
it is really the only significant difference.

Is $_SESSION slowing down my site?  Is there a faster alternative to
global variables then using $_SESSION?  Are using regular cookies faster?

Any help is appreciated.

Thanks,
  Scott

The register_globals value is something that cannot be set at runtime.
If you pass it to ini_set(), it will appear to work -- you won't get
an error and successive calls to phpinfo() will show the new value;
however, by the time PHP gets far enough down the chain to execute
your ini_set() command, PHP has already determined whether it should
register global variables. The manual indicates that this wasn't
always the case, but (not knowing the internals then or now) I don't
understand how. (The table on that page says it was PHP_INI_ALL for
versions up to 4.2.3.)

Hey!

I found it and you were right.

On my webbytedd.com site, I had a htaccess file that read:

AddDefaultCharset utf-8

php_value register_globals 0
php_value magic_quotes_gpc 0
php_value magic_quotes_sybase 0
php_value magic_quotes_runtime 0

And I didn't have that htaccess file on my sperling.com site. 
However, what fooled me was in both scripts I had:


ini_set( 'register_globals', '0' );

So, I thought that was the same, but apparently it's not. Maybe 
because my server had safe_mode ON it won't allow it -- I don't know. 
Another question for another time.

sorry tedd; obviously i was hasty to post.  but i figured just looking for
the obvious would be a good exercise as i cant count the times ive launched
into an exhaustive search for the problem when its really something silly
ive overlooked.  that said; i know ur smart and you always post hard
problems for 'the gang' ;)
anyway, taking the cue from some of the other responses, have you looked at
the page on session_write_close() ?
http://us2.php.net/manual/en/function.session-write-close.php
its kind of interesting; it looks like lots of people have run into issues
using the location header to redirect clients to another script after a form
submission.  its never happened to me (knock on wood) but anyway some of the
posts on that page may be worth reading.
also, though it wont answer your question about why its happening, i was
thinking you might alter the flow of ur scripts to see if you can get the
same behavior on both sites.  heres what i was thinking:
add a hidden input to the form (from index.php)



then after you call session_start() in index.php, have the following

if(isset($_POST['formsubmission']) && $_POST['formsubmission'] == '1')) {
include('part2.php');  // process form submission
}

then, make the following adjustments to part2.php

remove the call to session_start()
remove the call to header(location ...
remove the call to exit()

i think this will have the effect that the work flow is unaltered, but the
organization of the logic on the back end will be different.  effectively
the call to header(location... will be removed so we would be able to tell
if the issue is related to that.

It does to me, as well.  I know, Tedd, that on the php1.net site
that you mentioned to me off-list, I'm about 99% positive that it's
the reason.  Shared hosts generally keep register_globals on and leave
it up to the individual customer to turn it off.  On that particular
server, though, since it's mostly developers, I may just send out an
email to get feedback and turn it off at the main, and then allow
ya'all to override it on your individual sites.

The thing that makes me wonder (and I haven't checked myself to
verify) is why two sites, on the same server, having the same
phpinfo() output, would have different results.

it looks fine to me. but i want to share one bad experience with sessions.
the code i wrote work just fine on my testing server (please note, the
phpinfo is same with
my production server).

after days of figuring out why the session do not work. finally, i found the
solutions.
the solutions is to add a

@session_write_close() on the end of the execution code. on my case it
happen
every time i forward the page. so adding the @session_write_close before the
header('location: ') fix the problem.

this might be a possible explanation..

Don't rely on browser bugs and features present to work around popular

Sorry, that was my BUG!!

Your totally right and I know that. I was with my head at some other place
when I wrote that (probably).

I don't know that much of HTTP (or other protocols) but my knowladge
of (X)HTML (used by its semantic) is very good. Also, I use headers to
send files, images and document types and that's got nothing to do
with HTML.

Glad that you reminded me, thanks,
Nuno

It's not HTML, that's a completely different animal! HTTP is a transport
protocol, HTML is a document format.  HTML documents are but one type
of things you can transport using HTTP.

I've compared the php.ini files and can't find anything related to sessions
that is different. In fact they're almost the same with a few minor
exceptions that should have no effect that I can think of.

Here is the code I'm executing:

UserData array = \n";
print_r($UserData);

//set the session variables:
$_SESSION['login']  = true;
$_SESSION['ie'] =
(stristr($_SERVER['HTTP_USER_AGENT'],"MSIE")) ? true : false;
$_SESSION['id'] = $UserData['id'];
$_SESSION['username']   = $UserData['username'];
$_SESSION['firstname']  = $UserData['firstname'];
$_SESSION['lastname']   = $UserData['lastname'];
$_SESSION['email']  = $UserData['email'];
$_SESSION['foo']= '1234567890';

require_once('includes/classes/User.class.php');
$_SESSION['user'] = new User($UserData['id']);

echo "_SESSION array = \n";
var_dump($_SESSION);
echo "USERNAME = ".$_SESSION['user']->get_username()."\n";
exit;
?>

Which properly results in this (as it's all on the same page):

UserData array = 
Array ( [id] => 1 [firstname] => Daevid [lastname] => Vincent [email] =>
[EMAIL PROTECTED] ) 

_SESSION array = 
array(9) { ["login"]=> bool(true) ["ie"]=> bool(true) ["id"]=> string(1) "1"
["username"]=> string(6) "daevid" ["firstname"]=> string(6) "Daevid"
["lastname"]=> string(7) "Vincent" ["email"]=> string(17)
"[EMAIL PROTECTED]" ["foo"]=> string(10) "1234567890" ["user"]=>
object(User)#2 (24) { ["username:protected"]=> string(6) "daevid"
["firstname:protected"]=> string(6) "Daevid" ["lastname:protected"]=>
string(7) "Vincent" ["email:protected"]=> string(17) "[EMAIL PROTECTED]" ...
 } } 

USERNAME = daevid


Now I load a simple session loading test page with this code:

SESSION TEST:";
var_dump($_SESSION);
exit;
?>

On the working box things are fine (obviously): 

SESSION TEST:
array(9) { ["login"]=> bool(true) ["ie"]=> bool(true) ["id"]=> string(1) "1"
["username"]=> string(6) "daevid" ["firstname"]=> string(6) "Daevid"
["lastname"]=> string(7) "Vincent" ["email"]=> string(17)
"[EMAIL PROTECTED]" ["foo"]=> string(10) "1234567890" ["user"]=>
object(User)#1 (24) { ["username:protected"]=> string(6) "daevid"
["firstname:protected"]=> string(6) "Daevid" ["lastname:protected"]=>
string(7) "Vincent" ["email:protected"]=> string(17) "[EMAIL PROTECTED]"
["timestamp:protected"]=> string(19) "-00-00 00:00:00" ...  } } 

but on the broken box I see:

SESSION TEST:
array(9) { ["login"]=> bool(true) ["ie"]=> bool(true) ["id"]=> string(1) "1"
["username"]=> string(6) "daevid" ["firstname"]=> string(6) "Daevid"
["lastname"]=> string(7) "Vincent" ["email"]=> string(17)
"[EMAIL PROTECTED]" ["foo"]=> string(10) "1234567890" ["user"]=>
object(User)#1 (20) { ["username:protected"]=> string(0) ""
["firstname:protected"]=> string(0) "" ["lastname:protected"]=> string(0) ""

Notice how the regular session info is there, but the "User" class is all
empty or NULL. So SOME of the $_SESSION is working, but not the User class
portion. This is completely baffling to me. Examining the /tmp/sess_* file
shows this same data.

Here is the session portion of php.ini on the broken box:

[Session]
; Handler used to store/retrieve data.
session.save_handler = files

; Argument passed to save_handler.  In the case of files, this is the path
; where data files are stored. Note: Windows users have to change this

;
; As of PHP 4.0.1, you can define the path as:
;
; session.save_path = "N;/path"
;
; where N is an integer.  Instead of storing all the session files in
; /path, what this will do is use subdirectories N-levels deep, and
; store the session data in those directories.  This is useful if you

RE: [PHP] $_SESSION saves all values but Class -- works on one server but not another?!

[Daevid Vincent]

You are correct, however that also seems to have to do with the actual class
or php code and not a server configuration. If I copy my PHP files to the
'other' server, everything works as expected -- no change in code required.
This is why I suspect it is a PHP/Apache/php.ini type of problem. But as I
tried to illustrate, the php.ini seems to be nearly the same on both
servers.

RE: [PHP] $_SESSION saves all values but Class -- works on one server but not another?!

[Daevid Vincent]

Thank you for the reply. I don't think that's the issue.

I have:

; Initialize session on request startup.
session.auto_start = 0

But this is the same setting as the box that DOES work.

What's really confusing me is that part of the SESSION does work. I would
expect an all or nothing case. Everything but the class is restored.

[PHP] $_SESSION saves all values but Class -- works on one server but not another?!

[Daevid Vincent]

I have a gentoo server that doesn't save/restore the CLASS portion of a
session, but it does retain other $_SESSION values. This code works fine on
a debian box.

I've compared the php.ini files and can't find anything related to sessions
that is different. In fact they're almost the same with a few minor
exceptions that should have no effect that I can think of.

Here is the code I'm executing:

UserData array = \n";
print_r($UserData);

//set the session variables:
$_SESSION['login']  = true;
$_SESSION['ie'] =
(stristr($_SERVER['HTTP_USER_AGENT'],"MSIE")) ? true : false;
$_SESSION['id'] = $UserData['id'];
$_SESSION['username']   = $UserData['username'];
$_SESSION['firstname']  = $UserData['firstname'];
$_SESSION['lastname']   = $UserData['lastname'];
$_SESSION['email']  = $UserData['email'];
$_SESSION['foo']= '1234567890';

require_once('includes/classes/User.class.php');
$_SESSION['user'] = new User($UserData['id']);

echo "_SESSION array = \n";
var_dump($_SESSION);
echo "USERNAME = ".$_SESSION['user']->get_username()."\n";
exit;
?>

Which properly results in this (as it's all on the same page):

UserData array = 
Array ( [id] => 1 [firstname] => Daevid [lastname] => Vincent [email] =>
[EMAIL PROTECTED] ) 

_SESSION array = 
array(9) { ["login"]=> bool(true) ["ie"]=> bool(true) ["id"]=> string(1) "1"
["username"]=> string(6) "daevid" ["firstname"]=> string(6) "Daevid"
["lastname"]=> string(7) "Vincent" ["email"]=> string(17)
"[EMAIL PROTECTED]" ["foo"]=> string(10) "1234567890" ["user"]=>
object(User)#2 (24) { ["username:protected"]=> string(6) "daevid"
["firstname:protected"]=> string(6) "Daevid" ["lastname:protected"]=>
string(7) "Vincent" ["email:protected"]=> string(17) "[EMAIL PROTECTED]" ...
 } } 

USERNAME = daevid


Now I load a simple session loading test page with this code:

SESSION TEST:";
var_dump($_SESSION);
exit;
?>

On the working box things are fine (obviously): 

SESSION TEST:
array(9) { ["login"]=> bool(true) ["ie"]=> bool(true) ["id"]=> string(1) "1"
["username"]=> string(6) "daevid" ["firstname"]=> string(6) "Daevid"
["lastname"]=> string(7) "Vincent" ["email"]=> string(17)
"[EMAIL PROTECTED]" ["foo"]=> string(10) "1234567890" ["user"]=>
object(User)#1 (24) { ["username:protected"]=> string(6) "daevid"
["firstname:protected"]=> string(6) "Daevid" ["lastname:protected"]=>
string(7) "Vincent" ["email:protected"]=> string(17) "[EMAIL PROTECTED]"
["timestamp:protected"]=> string(19) "-00-00 00:00:00" ...  } } 

but on the broken box I see:

SESSION TEST:
array(9) { ["login"]=> bool(true) ["ie"]=> bool(true) ["id"]=> string(1) "1"
["username"]=> string(6) "daevid" ["firstname"]=> string(6) "Daevid"
["lastname"]=> string(7) "Vincent" ["email"]=> string(17)
"[EMAIL PROTECTED]" ["foo"]=> string(10) "1234567890" ["user"]=>
object(User)#1 (20) { ["username:protected"]=> string(0) ""
["firstname:protected"]=> string(0) "" ["lastname:protected"]=> string(0) ""
["email:protected"]=> string(0) "" ["timestamp:protected"]=> NULL ... 
} }

(c) needs  at the top, just like (a) and (b) and
(z) for any other page you want to use your session data.

Also, *WHY* redirect the browser and chew up an HTTP connection and make
your application twice as slow?

Plus, with the session_start() in there, you're going to duplicate all the
effort you've already gone to to build up the session data structure
(overhead).

At that point in your script, you could just "include" (c) and be done
with it.

It's a heck of a lot easier to debug without feeling like you're the
pinball in a fast-paced game of HTTP redirects, imho.

You also make life easier on cURL and other programmatic access of your
site, if you don't force them to play "follow the bouncing ball" to track
down what they asked for.  Just give it to them already. :-)

I played with header("Location: ") in my early PHP days, and stopped using
it rather quickly, unless I actually have a URL I want to maintain for the
search engines for awhile, but the document has actually moved.

Just because the re-direct works doesn't make it the best answer.

Others on this list just LOVE to have a bunch of header("Location: ")
statements in their PHP code, so you are not alone.

Just something to think about. :-)

Thank you both!
I did always use session_start() and finally I also already use
the second option Paul addressed, in order to overcome the
issues raised by header(). Not in the same terms, but the URL
parameters was my idea too.

So could I guess that this is there's no direct remedy to
avoid header() delete sessions variables?:-)

You have to pass the session ID between pages, either by setting
session.use_cookies = 1 (so that the session ID is passed using a
cookie where possible) or append the session ID to the URL you are
redirecting to as part of the query parameters.

[PHP] $_SESSION and header()

[Alessandro Rosa]

(a) : After saving a couple of data into two $_SESSION variables from a
form,
(b) : I used the header() function to redirect the browser to
(c) : display another page.

But, when I'm in the new page of (c), the $_SESSION variables stored
in (a) are no longer available and I can get anymore their values then,
(I can't say if they have been unset or erased).

I presume there's some relation with the use of header() and
the lost data.
My intention is to keep the automatic redirection by the header().

Any suggestion?
Thanks in advance.

[PHP] $_SESSION

[Dennis Koot]

Hello all,

i have a question concerning the $_SESSION stuff.
i have a domain registered with online webspace on this webspace i have put a litte 
bit of code that will send the visitor's of the website to my server using a frame. I 
open one frame full-screen size and i let it open MY_IP/base/index.php as page.
i then have a login page which uses $_SESSION and which sends you to either 
MY_IP/login1/index.php or MY_IP/login2/index.php depending on your username. (which 
are stored in mysql)
this all works fine. i get redirected to the right page and all. but then on the new 
page the session doesn't work anymore.
so the user gets a error for not being logged in and returns to the login page at /base

AND here's the strange thing.. when i open it using the http://MY_IP link it all works 
great.
it just doesn't when i use the frame via my hosting provider. So i tried to make a 
fram on my site which is exactly the same as the frame at the hosting provider. And it 
all works great aswell. just not when i place the frame at my Hosting Prov. 

has anybody got a clue how to do this?

thanx

Dennis

[PHP] $_SESSION <- Learning

[Ross Bateman]

Hi

I am finally starting to try and use register_globals = off on my Servers.
This means a lot of code that has to be checked and changed.

Unfortunatly I am struggeling to come to grips with this new concept (new to
me that is) and was wondering if anybody could give me some pointers.

Getting stumped at my login script.
Once I have checked user and passwords, I pass a few SESSION vars to use
throughout my app.


if ($status == 1)
   {
   //initiate a session
   session_start();
   //register session variables
   $_SESSION['SESSION'];
   //Get DataBase details and connect to it
   include($root_path . "include/vars.php");
   $query = "SELECT * FROM admin WHERE user_name = '$user'";
   $result = mysql_query($query);
   $row = mysql_fetch_object($result);
   //include the username
   $_SESSION['SESSION_UNAME'] = $row->user;
   //include the user id
   $_SESSION['SESSION_UID'] = $row->admin_id;
   //set the SecLevel Session Var
   $_SESSION['SESSION_SEC'] = $row->sec_level;
   //Now do the redirect
   //redirect to Admin Page
   header("Location: ./admin_main.php");
   exit();

   }
else


Where ever I have the $SESSION['var_name'] I used to have a
session_register("SESSION_VAR");
$SESSION_VAR = $row->user;

I then redirect to my app main page and check if a session is registerd to
make sure a user is logged in:

//check that each page is secure
session_start();
//OLD CODE IN SCRIPT = if (!session_is_registered("SESSION"))
if(isset($_SESSION['SESSION']))
   {
   //if session check fails, invoke error handler
   header("Location: ./../error.php?e=2");
   exit();
   }
?>

That all works fine, but when I finaly start to display data on the main
page, nothing shows up.

One of the things I try to display is the name of the user logged in:
>From the login script
//include the username
$_SESSION['SESSION_UNAME'] = $row->user;

then on my main page
echo "logged in as " . $_SESSION['SESSION_UNAME'] . " ";

Needless to say, no data is displayed. anybody able to point out what I
am getting wrong here. It used to work fine before the old way with
register_globals = on.

SIDE Note:
On a Windows PC with Apache, PHP and MySQL installed, even with the
register_globals = on set, the SESSION vars do not work.

Thanks and sorry for the long post,

Ross

RE: [PHP] $_SESSION vs Database Call

The difference between the two probably works out to less than 10
milliseconds on most servers, from a quick study that I ran on some HP
servers that were brand new last summer, with the faster times using the
filesystem.  Course, the flexibility gained in managing the database version
caused us to ask, would any of our users notice a 10 millisecond difference
in response?  Answer was; only the paranoid would notice the difference ;-).
Course our user population was relatively small (100 - 500 concurrently
signed on).

to display this var again I get either an Undefined index or variable.
According to the docs $_SESSION[] is now global and this is the way of
setting and retrieving session objects, right?
I have tried calling that session object again but it's empty and so is the
variable.  I thought that the session would stay open until I close the
browser and I could return those values any time I wanted.  Am I missing
something?
Are you starting the session on each page?

You need to use session_start() before any headers are written.

[PHP] $_SESSION

[Alex Hogan]

I've got a question that I'm sure has a simple answer.

 

Why aren't my session objects transferring across more than one page?

 

I'm calling a session object that was set in the page prior;

$_SESSION['mysessionvar'] = $_REQUEST['mytxtobj'];

 

I then assign a variable that value;

$myvar = $_SESSION['mysessionvar'];

 

echo $myvar;

 

This displays like I expected.  However when I go to the next page and want
to display this var again I get either an Undefined index or variable.
According to the docs $_SESSION[] is now global and this is the way of
setting and retrieving session objects, right?

 

I have tried calling that session object again but it's empty and so is the
variable.  I thought that the session would stay open until I close the
browser and I could return those values any time I wanted.  Am I missing
something?

Re: [PHP] PHP $_SESSION Expiring in IE

Guess I'm being nosy here, so forgive me, but why are you settting an
alternate save path and using ini_set at the start of each document?  I know
that has nothing to do with the problem, but I was just wondering.  Are you
hosting multiple sites off your server and have different session settings
depending on the site?

IE and Moz have different JAVA script engines.  Try turning off JAVA and 
see if IE maintains it's session.

Doesn't seem to have solved the problem... My session include file at
the top of all documents looks like:

session_save_path("$some_path/sessions"); 
ini_set('session.use_cookies', 1);
ini_set('session.gc_probability', 1);
ini_set('session.gc_maxlifetime', 60 * 60);

session_start();

Have you tried the header(Cache-control: private) workaround for IE6?  I
seem to remember reading something about that on one of the web dev

and see if it makes a difference.

RE: [PHP] PHP $_SESSION Expiring in IE

[Tarrant Costelloe]

"Are there any points in the program that redirect the user off site and
back or something with that affect that IE might be handling in a weird
way?"

Nope

"Do you have pages that detect the browser and feed alternate content
based on the browser?"

Nope

"do you always run the session_start before these checks?"

Yes.

The only other thing I guess it could be is the .htaccess mod_rewrite
maybe? It's just weird that Internet Explorer is the only browser that
seemingly looses the members $_SESSION where as Mozilla is not effected
whatsoever.

I use sessions with IE all the time without such a problem.  Are there
any points in the program that redirect the user off site and back or
something with that affect that IE might be handling in a wierd way?  Do
you have pages that detect the browser and feed alternate content based
on the browser?  If so do you always run the session_start before these
checks?

Hello,

I have recently launched the new Planet-Tolkien.com, one would think
that writing a message board from scratch and a dynamic weather system,
a simple session login would be the least of my problems right? Wrong.

It would appear that for Mozilla and Opera keep a $_SESSION is not an
issue and the $_SESSION is continued until the member logs out. However
when members are using Internet Explorer browser (most versions it
seems), they can go around the site for varied amounts of time, usually
less than five minutes and then their $_SESSION will expire!!??

I cannot for the life of me figure out why a server side $_SESSION would
expire on IE but not for MOZ or Opera but it is, and I need to figure
out why and how can I fix this.

REF. All login information is saved as such:

session_save_path("$path/sessions");
session_start(); $_SESSION['session_memberID']=$session_memberID;
$_SESSION['session_username']=$session_username;
$_SESSION['session_groupID']=$membergroup;
