However, due to the nature of your test page you are still
sending output from the first loop before you call session_start() in
the second loop.
Duh!
Too many brain surgeons working on this brain!
In the real world neither of us would have made those mistakes.
It is only when we try to make things simple do we over complicate.

Thanks Jim -- you're right.
What about?

}
Before you answer, the (!defined(SID)) is over 50 times slower than (

Your way is better.
Cheers,

tedd,
I think this is because you passed SID to defined() as a constant
rather than a string, so the if test always returns true. When I
changed this to
if (!defined('SID'))
{
session _start();
}
it worked as expected, and I got much more similar results. I also
added a call to session_destroy() between the two tests so that each
loop initialized the session once. (In your test, the second loop
never initializes the session since it was already started by the
first loop.)
This is your code with my modifications:
?php
$starttime = microtime(true);
// whatever you want timed, you do here.
for($i=1; $i 1000; $i++)
{
if (!defined('SID'))
{
echo __LINE__, '::session_start()br';
session_start();
}
}
session_destroy();
$endtime = microtime(true);
$totaltime = $endtime - $starttime;
$totaltime = round($totaltime,5);
echo pFirst in $totaltime seconds./p;
$starttime = microtime(true);
// whatever you want timed, you do here.
for($i=1; $i 1000; $i++)
{
if (session_id() ==='')
{
echo __LINE__, '::session_start()br';
session_start();
}
}
$endtime = microtime(true);
$totaltime = $endtime - $starttime;
$totaltime = round($totaltime,5);
echo pSecond in $totaltime seconds./p;
session_destroy();
?

I've seen a lot of people code that way, so it's easy to miss. In your
original code, that first statement was calling session_start() 1,000
times. This is because the first time through, SID is undefined so
defined(SID) was equivalent to defined('SID') and both would have
returned false. After the first session_start(), though, SID WAS
defined, but would have had some pseudo-random session identifier as
its value. As a result, the last 999 times through your loop, you were
actually scanning the defined constants to see if there was one named
something like '7cjubadsh5lkq80opemht2ea03'. Obviously, it would never
exist.
However, my only concern is given this:
for($i=1; $i 1000; $i++)

Yes, that is more correct. I think we have output buffering enabled on
most of our servers (a lot of our legacy stuff really depends on it)
so I didn't notice any errors, but you are correct. You really don't
need the echo lines that I added in your test at all though. I just
threw it in there to be able to see when the function was being
called. However, due to the nature of your test page you are still
sending output from the first loop before you call session_start() in
the second loop. To be absolutely correct, you'd have to remove those
echo statements I added for debugging, store all of your timings in
separate variables and then output them at the end of the script.

Re: [PHP] session variables in tmp
Thanks Gerardo. I send a large dump.sql file to my /tmp dir and filled up the remaining space so PHP was not able to write any more session variable. Took me a little while to figure that one out.

Re: [PHP] session variables and SVG documents
Hello,
unfortunately, it does not suite my needs. The image must be clickable. The
application I'm developping reads data from a database and display the
information graphically. The user must be able to click on some elements of
the picture, and I have to store the information the user clicked on
(session vars). I cannot tell the user not to use IE, so I have to find
another solution...

Hello,
I have the following problem with the Adobe SVG viewer:
I try to generate a SVG document using PHP. the following code is working
well under Firefox, as well as IE with ASV:
?php
header(Content-type: image/svg+xml);
$graph_title = 'title';
print('?xml version=1.0 encoding=iso-8859-1 standalone=no?');

It appears IE does not support svg yet and you need a plugin for it.
However, you could also design your code differently by using Imagemagick
to convert the svg to png.
If that suits your needs, then use the modified code below:
?php
header(Content-type: image/png);
$graph_title = 'title';
$svgwidth=500;
$svgheight=400;
$svg = '?xml version=1.0 encoding=iso-8859-1 standalone=no?
svg width='.$svgwidth.'px height='.$svgheight.'px xmlns=
http://www.w3.org/2000/svg;
descThis is a php-random rectangle test/desc';
for ($i = 0; $i 20; $i++) {
$x = floor(rand(0,$svgwidth-1));
$y = floor(rand(0,$svgheight-1));
$width = floor(rand(0,$svgwidth-$x));
$height = floor(rand(0,$svgheight-$y));
$red = floor(rand(0,255));
$blue = floor(rand(0,255));
$green = floor(rand(0,255));
$color = rgb(.$red.,.$green.,.$blue.);
$svg .= \trect x=\$x\ y=\$y\ width=\$width\
height=\$height\ style=\fill:$color;\/\n;
}
$svg .= 'text x='.($svgwidth/2).'px y=300 style=font-size:15;

IE doesn't display SVG natively, and the plugins for it are pants.
However, IE does make use of its own propitiatory vector language called
VML, This is how the Cufon font replacer system works.

It sounds like it's the SVG plugin you're using on IE that's badly
misbehaving. That said, I've not seen any plugins that correctly pass
across the full headers that the browser would. I tried using sessions
once to secure media files by checking for a valid login against the
session id, but the plugins requesting the video clips didn't send any
cookie data in the header request. As such, it might be better to not
rely on it in this case.
Thanks,
Ash

It appears IE does not support svg yet and you need a plugin for it.
However, you could also design your code differently by using Imagemagick to
convert the svg to png.
If that suits your needs, then use the modified code below:
?php
header(Content-type: image/png);
$graph_title = 'title';
$svgwidth=500;
$svgheight=400;
$svg = '?xml version=1.0 encoding=iso-8859-1 standalone=no?
svg width='.$svgwidth.'px height='.$svgheight.'px
xmlns=http://www.w3.org/2000/svg;
descThis is a php-random rectangle test/desc';
for ($i = 0; $i 20; $i++) {
$x = floor(rand(0,$svgwidth-1));
$y = floor(rand(0,$svgheight-1));
$width = floor(rand(0,$svgwidth-$x));
$height = floor(rand(0,$svgheight-$y));
$red = floor(rand(0,255));
$blue = floor(rand(0,255));
$green = floor(rand(0,255));
$color = rgb(.$red.,.$green.,.$blue.);
$svg .= \trect x=\$x\ y=\$y\ width=\$width\ height=\$height\
style=\fill:$color;\/\n;
}
$svg .= 'text x='.($svgwidth/2).'px y=300 style=font-size:15;
text-anchor=middleThe servers Date and Time is: '.date(Y-m-d,
H:m:s).'/text
text x='.($svgwidth/2).'px y=340 style=font-size:15;
text-anchor=middleYou are running:/text
text x='.($svgwidth/2).'px y=360 style=font-size:15;
text-anchor=middle'.$HTTP_USER_AGENT.'/text

file_put_contents('/tmp/image.svg', $svg);

RE: [PHP] SESSION VARIABLES ACROSS DIFFERENT WINDOWS/TABS
Hi Jamie. Thanks. Good info. I knew something changed somewhere. This works like a charm in IE8..never saw the New Session option under file...me bad !! Greetings. -Original Message- From: Jaime Bozza [mailto:jbo...@mindsites.com] Sent: 20 August 2009 09:49 PM To: Leon du Plessis; 'Floyd Resler' Cc: a...@dotcontent.net; php-general@lists.php.net Subject: RE: [PHP] SESSION VARIABLES ACROSS DIFFERENT WINDOWS/TABS Leon, This is really just a function of the browser. When a session cookie is created, if the browser is setup for a single instance, that's the session cookie it'll use for *any* request to that domain. This functions differently depending on what browser you're using. For example: Firefox - All windows, tabs, etc, under the same profile will use the same session. If you create profiles, you can have different sessions. IE7, IE6 - All tabs or windows opened from clicks will share the same instance/session. Starting IE from the icon will open up a new instance/session. This worked great if you wanted to run two different sessions at the same site/domain. Just start IE up from the icon again and you'd have a new session. IE8 - IE8 model changed, so that all browser windows, tabs, etc., run under the same frame/session, much like Firefox. Clicking the IE icon again now just keeps the same frame and thus the same session. Originally, this sounded like a big problem, but IE8 introduced a new feature - File Menu - New Session. This will open up a new window that will be a separate frame that will not use current session cookies. Here's just one of many links, but gives some helpful hints on the IE side: http://blogs.msdn.com/ie/archive/2009/05/06/session-cookies-sessionstorage-a nd-ie8.aspx And another: http://blogs.msdn.com/askie/archive/2009/05/08/session-management-within-int ernet-explorer-8-0.aspx One of the issues now is that if you close IE, your session does not disappear. In the past (IE7/IE6), your session would disappear if you closed a browser window that you opened yourself, but it *wouldn't* disappear if you closed a browser window that was opened by a click from Outlook or another program. This was a bit inconsistent. I won't argue whether or not their fix was the best way to go, but now it's at least consistent. Note - In Firefox, not even Private Browsing separates the session cookies. If you start Private Browsing (Firefox 3.5), log into a site, then start a new browser window from the icon (that isn't in Private Browsing mode), it shares the session cookies. (Before you ask, I just checked this to be sure.) IE8 InPrivate Mode is a totally separate session, cookies and all. This could possibly be another way for you to run multiple sessions against the same domain. OTOH, multiple InPrivate sessions running at the same time share the same frame, so they share the same session, so it would only be good for a single new session. If you need more, just use File - New Session.

Re: [PHP] session variables - help
I'm realy sorry for u, but the reason for no answers is ur concept.
may be some rules will help u and I recommend u to think to spend the time
to rewrite the whole code. Im shure u will solve the problem then:
first dont use the global arrays directly. pick the values u need and put
them in reasonable types of variables.
build the business logic on these variables and if u feel like put the
results in well readable new ones
then populate the presentation in the required htmls
this will give u an more structured code, easier to debug and more fun for
the group to help u
I still dont understand why u use the $_SESSION variable. user often leave
forms open for hours and then submit them. u can not expect a user to end a
job in the livecycle of the session. thats what hidden form fields are made
for.
the $_session is for member like things and applications with security
issues where u can expect the user to finish things in a certain time or u
restart the whole.

Ben,
First of all, I thank you for your time and help.
My ai with using unset($var) in update_order.php is to set the SESSION
variable for an item to ' ' (empty) so that it would not show up on the
order summary (because my writeResultRow() function will only write a row
if
that variable is greater than 0).
I just can't figure out what I'm missing here. Before I received your
response, I made a few changes to my code, which helped streamline the
calculating parts (grabbing values from SESSION instead of POST, and now
when I update order_summary, the values will remain because it pulls them
from the SESSION).
I want to edit the values in the SESSION, so that when update_order.php
redirects to order_process.php, the values are changed, and if applicable,
an item is removed from the html table (if the quantity is less than 1).
Here is some more complete code:
[code = order_process.php]
?php
session_start();
// POST ALL $_POST VALUES, CREATE AS VARIABLES IN SESSION
foreach($_POST as $k=$v) {
$_SESSION[$k]=$v;
}
$thisPage=AFY; //NAVIGATION PURPOSES
include(afyshows.php); //CONTAINS ARRAYS FOR SHOW ENTITIES; POPULATES

?
. . .
/pform name=update action=update_order.php method=post

?
/
input type=hidden name=Email id=Email value=?php
$_SESSION['Email']; ? /
. . .
?php
function findTotalCost($b, $c) {
$total = $b * $c;
return $total;
}
function writeResultRow($a, $b, $c, $d, $e, $f) {
if($a != '') {
echo \ntr\n\t;
echo td'.$b./tdtd.$c./tdtd.$d./td;
echo td.$e./tdtdnbsp;/tdtdinput type='text'
value='.$a.'
name='.$a.' id='.$a.' size='2' //tdtd=/tdtd\$.$f./td;
echo /tr;
}
}
//SETS $Total_show_01 to PRICE * QUANTITY
//FORMATS TOTAL
//IF A QUANTITY IS ENTERED, WRITES THE ROW WITH CURRENT VARIABLES
$Total_show_01 = findTotalCost($shows['show_01']['price'],
$_SESSION['show_01_qty']);
$Total_show_01_fmtd = number_format($Total_show_01, 2, '.', '');
writeResultRow($_SESSION['show_01_qty'], $shows['show_01']['title'],
$shows['show_01']['date'], $shows['show_01']['time'],
$shows['show_01']['price'],$Total_show_01_fmtd);
//ABOVE LINES REPEATED FOR ALL 38 ENTITIES (show_01 to show_38)
?
. . .
input name=updates id=updates type=submit value=Update/
[/code]
Now, here is the update_order.php code in entirety:
[code]
?php
session_start();
foreach ($_SESSION as $var = $val) {
if ($val == 0) {
unset($_SESSION[$var]);
} elseif ($val == '') {
unset($_SESSION[$var]);
} else {
$val = $_SESSION[$var];
}
}
header(Location: order_process.php);
//NOTICE I FIXED THE LOCATION OF THE header() FUNCTION
//BUT IT STILL DOES NOT UPDATE
?
[/code]
If you're still with me, I thank you. I removed all the styling elements
from the html to make it easier for you (and me) to see what it says. I
have
invested many hours into this, and have generated many many lines of code,
but I hope what I gave you is sufficient, while not being overwhelming at
this hour.
Thank you very much for your help thus far, anything else would be greatly
appreciated.

response, I made a few changes to my code, which helped streamline
the
calculating parts (grabbing values from SESSION instead of POST, and
now
when I update order_summary, the values will remain because it pulls
them
from the SESSION).
I want to edit the values in the SESSION, so that when
update_order.php
redirects to order_process.php, the values are changed, and if
applicable,
an item is removed from the html table (if the quantity is less than
1).
Here is some more complete code:
[code = order_process.php]
?php
session_start();
// POST ALL $_POST VALUES, CREATE AS VARIABLES IN SESSION
foreach($_POST as $k=$v) {
$_SESSION[$k]=$v;
}
This has just destroyed anything that was previously in the session, so if
you're recycling from the update_order.php script, you've just thrown away
whatever that script did! You need to make this conditional on having arrived
here from the initial form -- various ways you could do that, but I leave you
to figure that one out.
(Also, personally, if I were doing this at all, I would just copy the array as
a single entity:
$_SESSION['_POST'] = $_POST;
and then reference individual elements through that as, e.g.,
$_SESSION['_POST']['School']. That's probably a matter of personal style as
much as anything, but gives you another way to think about.)
[ . . . . ]
?php
function findTotalCost($b, $c) {
$total = $b * $c;
return $total;
}
function writeResultRow($a, $b, $c, $d, $e, $f) {
if($a != '') {
echo \ntr\n\t;
echo td'.$b./tdtd.$c./tdtd.$d./td;
echo td.$e./tdtdnbsp;/tdtdinput type='text'
value='.$a.'
name='.$a.' id='.$a.' size='2'
//tdtd=/tdtd\$.$f./td;
echo /tr;
}
}
//SETS $Total_show_01 to PRICE * QUANTITY
//FORMATS TOTAL
//IF A QUANTITY IS ENTERED, WRITES THE ROW WITH CURRENT VARIABLES
$Total_show_01 = findTotalCost($shows['show_01']['price'],
$_SESSION['show_01_qty']);
$Total_show_01_fmtd = number_format($Total_show_01, 2, '.', '');
writeResultRow($_SESSION['show_01_qty'], $shows['show_01']['title'],
$shows['show_01']['date'], $shows['show_01']['time'],
$shows['show_01']['price'],$Total_show_01_fmtd);
//ABOVE LINES REPEATED FOR ALL 38 ENTITIES (show_01 to show_38)
AARRRGHHH!!
This cries out for an array-based solution -- repeating near-identical code
that many times is totally ludicrous, and should be a major clue that you need
to refactor. You'll have to forgo using indexes like ['show_01'] and use
straight integers, but the massive reduction in repetitive code (and hence far
fewer opportunities for mistakes!) will be well worth it.
Something like:
for ($i=1; $i=38; ++$i):
$Total[$i] = findTotalCost($shows[$i]['price'], $_SESSION['qty'][$i]);
$Total_fmtd[$i] = number_format($Total[$i], 2, '.', '');
writeResultRow($_SESSION['qty'][$i], $shows[$i]['title'],
$shows[$i]['date'], $shows[$i]['time'], $shows[$i]['price'],$Total_fmtd[$i]);
endfor;
[ . . . . ]
Now, here is the update_order.php code in entirety:
[code]
?php
session_start();
foreach ($_SESSION as $var = $val) {
if ($val == 0) {
unset($_SESSION[$var]);
} elseif ($val == '') {
unset($_SESSION[$var]);
} else {
$val = $_SESSION[$var];
That line is back-to-front -- you're assigning the current value in the session
to $val, which is then immediately thrown away as the foreach loop starts a new
iteration. What you mean is $_SESSION[$var] = $val.
Cheers!

If I'm reading what you want to do correctly, it seems to me there are two
obvious approaches to this:
(i) Have a single form which posts back to itself, showing all the show
information and requested quantities and calculated result fields (such as
total cost); initially, this will have the calculated fields not displaying
anything, and these will be (re)populated at each Update. Using this method,
all your values are contained solely within the $_POST array.
(ii) Have your initial form post to the process form, which then also posts to
itself on Update. This process form will have visible fields only for values
which can be changed, but *must* then contain hidden fields for all the other
values which were originally passed in the $_POST array. This arrangement
means that the process form always receives a full complement of values in the
$_POST array -- either from the original form, or from hidden fields posted
back to itself.
This is all just coming off the top of my head, and I'm sure there are
improvements/other solutions to be offered. Hope this will give you some
things to think about, and maybe a pointer or two towards a satisfactory
solution.
Cheers!

Re: [PHP] session variables - help
Thank you all for your responses.
Mike.
I like the ii option better, mostly because I already have most of that in
place (ie. order posts to process, and process has editable fields and
hidden fields with the remaining complimentary values).
Martin suggested I use the following code for my update script (which is
posted to via the process page):
[code]
foreach($_POST as $key = $value)
if( '0' == $value || '' == $value )
{
/*if*/ session_is_registered( $key )
session_unregister( $key );
}
[/code]
I am not following the logic on the above code very well, but is this indeed
a better option? And is not session_*whatever deprecated? The reason I am
using $_SESSION is because it seems that php 6 will use solely this method,
and it currently works with php 5. The other reason I am using it is so that
I can keep the variables stored elsewhere for whenever I need them; I don't
want to have to juggle all the information with POST and hidden inputs
unless it will work seamlessly, and be ready for update at a later date (if
I move to using a database to store show information, or when php 6 is
mainstream).
Keep in mind that once I get the update feature working, I need the process
page to have a final submit button that will insert the order into a
database table AND send a notification email to myself (and an email to the
user). Am I setting myself up for failure with this udate order option? I
ask because the update feature relies on a form, and are not forms limited
to one submit button?
Thanks all for your patience! I will work on this today and write back with
any further questions I can't figure out on my own. And if anyone has any
advice I will be checking my email regularly.

Thanks all for your patience! I will work on this today and write back with any further questions I can't figure out on my own. And if anyone has any advice I will be checking my email regularly. If you've already tried this with no luck, please ignore -- but you might speed up the whole process by stepping aside from the real code briefly, starting fresh in an empty directory, and just putting together a handful of extremely simple scripts with the single goal of entering one value, updating it, and then doing some final pseudo-processing on the updated value. Then, you could step it up a bit by by adding a second value that gets entered at the beginning, and cannot be updated in the middle but must be preserved through to the end. Doing all this might help clarify the basic flow of the system and enable you to simplify its structure before going back and tackling the real code.

Re: [PHP] session variables - help RESOLVED
Thanks everyone for your help, I finally got it working. For those that were curious, my writeResultRow() function was not naming the input fields properly, so the SESSION variables could not be updated properly. I had to add an array item for each show, an id, then call the id to name the inputs with.

[PHP] session variables - help
I am asking a similar question to one I asked yesterday (which received no
answers) with more information in the hopes someone will be kind enough to
guide me.
I have an order form populated with an array (as opposed to a database
table). The user can enter quantities, and the form posts all the
information to the order_process page where the values they entered are
listed for review.
I decided I wanted to allow them to edit quantities before actually
submitting the form (by which I mean before using the mail() function).
I found that $_SESSION is the way to go.
On the order summary page (order_process.php), I start a session and I get
all the POST information via:
[code]
session_start();
extract($_POST);
[/code]
Instead of echoing the quantity values of each item, I populate an input
field with them within an echo:
[code]
//when this function is called, $a is a the quantity variable $show_01_qty
function writeResultRow($a, $b, $c, $d, $e, $f) {
if($a != '') {
echo trinput type='text' value=' . $a . ' name=' . $a . ' id='
. $a . ' size='2' //td;
. . .
}
[/code]
Now, in order to update a quantity, the user replaces the quantity in the
input field with the new number, and clicks a submit button which posts to
order_update.php.
I have the following code for order_update.php:
[code]
session_start();
extract($_POST);
foreach ($_POST as $var = $val) {
if ($val 0) {
$_SESSION[$var] = $val;
} else {
unset($var);
}
header(Location: order_process.php);
}
[/code]
This is not working, however, and it just loads order_process.php with no
values for the varaibles, as if I just refreshed the page with no sessions.
Help please!

Maybe you left it out but I didn't see any place where you used $_SESSION in
order_process.php. Also, your redirect in order_update.php appears to be
inside your foreach loop, which would definitely mess things right up -- but
maybe that was just a typo in your email?
Otherwise the logic in order_update.php looks OK, but there are a few side
notes that jumped out:
1. I'm not seeing why you used extract($_POST) in order_update.php. Right
after the extract() call, you iterate through $_POST with a foreach loop, so
what's the purpose of calling extract()? Is there more code that you left
out?
2. Calling extract($_POST) is dangerous. The PHP manual warns against it,
although without giving much of an explanation:
http://us2.php.net/manual/en/function.extract.php
Apart from making it difficult to filter the input you're expecting to see,
extract($_POST) also allows a malicious end-user to define any variable of
his choosing and to overwrite any variables that you may have defined in the
script before the extract() call.
I like to use filter_input() to read the values of POST variables.
By much the same token, you'll want to escape $a, etc., in your
writeResultRow() function, with something like htmlentities().
3. Why the unset($var) in order_update.php? $var already gets reset each
time foreach iterates. So, calling unset() on it at the end of the loop
doesn't really do much. I'm wondering what you were aiming at there.
Thanks,
Ben
Re: [PHP] session variables - help
Ben,
First of all, I thank you for your time and help.
My ai with using unset($var) in update_order.php is to set the SESSION
variable for an item to ' ' (empty) so that it would not show up on the
order summary (because my writeResultRow() function will only write a row if
that variable is greater than 0).
I just can't figure out what I'm missing here. Before I received your
response, I made a few changes to my code, which helped streamline the
calculating parts (grabbing values from SESSION instead of POST, and now
when I update order_summary, the values will remain because it pulls them
from the SESSION).
I want to edit the values in the SESSION, so that when update_order.php
redirects to order_process.php, the values are changed, and if applicable,
an item is removed from the html table (if the quantity is less than 1).

If you're still with me, I thank you. I removed all the styling elements
from the html to make it easier for you (and me) to see what it says. I have
invested many hours into this, and have generated many many lines of code,
but I hope what I gave you is sufficient, while not being overwhelming at
this hour.
Thank you very much for your help thus far, anything else would be greatly
appreciated.

This is not working, however, and it just loads order_process.php with no
values for the varaibles, as if I just refreshed the page with no
sessions.
Maybe you left it out but I didn't see any place where you used $_SESSION
in order_process.php. Also, your redirect in order_update.php appears to be
inside your foreach loop, which would definitely mess things right up -- but
maybe that was just a typo in your email?
Otherwise the logic in order_update.php looks OK, but there are a few side
notes that jumped out:
1. I'm not seeing why you used extract($_POST) in order_update.php. Right
after the extract() call, you iterate through $_POST with a foreach loop, so
what's the purpose of calling extract()? Is there more code that you left
out?
2. Calling extract($_POST) is dangerous. The PHP manual warns against it,
although without giving much of an explanation:
[PHP] SESSION variables: How much is too much?
Hi, I'm trying to learn php mostly by reading the docs and pulling through other peoples projects for reference examples. One particular application I'm looking at has a ton of variables being handled through the SESSION global variable, probably about 25 or so variables. That just seems like alot. Since I'm pretty new to php I was wondering if this was typical and acceptable or if there was another best practice for maintaining large amounts of information throughout a session, like maybe persisting a temporary object in the database and passing a connection...or something. Or is just passing around a pile of variables directly in the SESSION object better? Thanks, Mark -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Since this session variable survives across page loads (assuming session_start() is appropriately called), how is it stored and recalled? Is it automatically stored as a cookie on the user's system?

If the value I've asked the user for is *not* stored as a cookie, then is it passed as part of the HTTP submission or what? Thanks for any enlightenment on this. Session data is stored on the server and tied to a browser using a cookie. The cookie contains a random string which uniquely identifies a session on the server. The session_start() function handles all the details of setting and maintaining that cookie and managing the server-side data.

Re: [PHP] Session variables
The session data is stored on the server. In the user's browser, only a session cookie is stored, usually a random session id string. I could never retrieve the session variables with any browser tools, always only with PHP by echoing them out or something. Also, a cookie is simply a text file with a maximum of 4096 characters on the user's browser, not enough to store big session variables with big objects. So, the user's browser just stores a cookie with the session id, so that the server knows which user to map to which session variables. The session variables (in PHP) are stored in the temporary directory on the server in a text file (flattened or serialized), where the server can retrieve them across requests. This is important for security reasons. You might not want the user to be able to view certain variables in their browser otherwise they could change them and cause some damage, e.g. imagine a user has a permission level between 1 and 10 and 1 is the super user. You can store this level in a session variable, and the user cannot change it. If they could, it would be a disaster! Also, if one could store more than 4096 characters, it would be relatively easy to write out some session variables in order to flood the browser memory and make it crash or even worse. Oh, and the Cookies, as far as i know, are always sent in the http headers. They are stored on both client and server and can be set on both sides, with javascript or server side code (php). So they can only be checked in every request by the server side code, and while javascript is being executed on the client. Please correct me if I'm wrong because I would need to review a lot of code in which it is assumed that session variables are NOT stored on the user's machine. Makes sense?

[PHP] SESSION variables
I am programming a blog. index.php sets up the layout for the web page. This includes the heading, left hand and bottom menus. The content is loaded by the command: include($filename); the $_SESSION variables aren't available to files like blog.php . The session variables only work in the initial file, index.php.

When the table of contents is called (http://www.rons-home.net/page/blog/ ) the session variables are present. When an actual blog entry is displayed ( http://www.rons-home.net/blog/28/ ) the session variables aren't there. I am not sure what is happening / why.

[PHP] Session variables disappear (some of them only)
Hi ! I have a very weird issue since the last Apache upgrade (- 2.2.8-r3, a month ago), but I'm not sure it is related (well, I'm pretty sure it's not). Like many people, I've written an application that use PHP session variables, like $_SESSION[my_variable]. Sometimes (it doesn't happen all the time), _some_ of these variables are not written in the session file and they are lost after a simple header(Location:...); (same domain). The session file is in the right directory (permissions are fine), but some of my variables are missing. The facts : - Apache 2.2.9 + PHP 5.2.6_rc4 running on a Gentoo (up-to-date) - all my scripts begin with session_start(). I've tried to add session_write_close() before every header(Location:...) call, it doesn't help. - I didn't change anything in my program (it has been running just fine for 2 years), it just began to fail from time to time (I would say 10 times a day). There is no hidden unset() function : it would fail for everyone. - these variables are all set correctly, and they don't have reserved names. - only a few variables disappear, but they are always the same ones (could it depend on their position in the session file ?!?) - the session files are very small (max 100ko) - it seems that it doesn't depend on the browser, but IE6 and IE7 seem to be the most affected ones (it may be because my users mostly use these browsers). - I can't reproduce this issue from my local network (any OS/browser - it would be too easy :) - reverting to the previous stable Apache and/or PHP versions doesn't help. - I didn't change any php.ini directive. Any idea ? Thanks ! PS: if you need more details, just ask. The only thing I can't do is pasting the code : the scripts are quite huge. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

RE: [PHP] Session variables and words with spaces
Not sure why I would get a parse error, but that did correct the problem. I just completely missed the single quote. I never even clue'd in when I looked at the source of the page.

[PHP] php session variables limited to 1 character -- please help
Hi! I've got a very strange issue that is basically cutting off session variable data after 1 character. When I set the session variable as 50 it comes back as 5. When I set it to XYZ it comes back as X. I have a script that is taking $_GET['State'] variable and setting it to a session variable named $USER['State']. This worked fine until a few days ago, but now it's persistent! Any ideas what might be causing this?? I've searched the web/lists and can't find any reference. http://www.triptrivia.com/step2-debug.php?State=abc Thanks, Zac -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Session variables are not stored when set in implicitly called constructor!??
Hallo everybody,
hope I am writing to correct mailinglist(^_^*)...
I have troubles with sessions and descructor in php5. Can not set session
variable in destructor when it's called implicitly. Do You know solution
please?
I think problem is that session is stored before imlicit object destruction
*doh*
example.php:
?php
session_start();
session_register(variable);
// singleton for request
class Request {
function __destructor() {
$_SESSION[variable] = hallo;
}
}
$req = Request::getInstance();
$req-doSomeThink();
echo This should be hallo 2nd time: . $_SESSION[variable];//
unfortunatly this is not set
echo a href='example.php'Click and cry;-(/a;
// implicit desturctor call
?
Thank You very much...

[PHP] Session variables not unsetting
I'm having a problem with session variables. A site that works fine on my
local system (PHP 4.3.4) is not working on the live server (4.1.2). In both
cases, register_globals is OFF. Every page starts with session_start() and
I'm setting session vars by simply assigning them to $_SESSION, eg:
$_SESSION['message'] = Some message for the next page;
I have a function that is included into every page that goes like this:
function show_message() {
if(isset($_SESSION['message'])) {
echo $_SESSION['message'];
unset($_SESSION['message']);
}
}
Calling tha function prints the message okay, but doesn't unset the session
var, so once the message is set, it shows on every subsequent page until
set to a different message. I even tried using
session_unregister($_SESSION['message']) even though the manual says not
to. What am I missing here?

That's not true, since he's using user data in the SQL statement. The query method has nothing to do with whether data should be escaped. Of course, addslashes() is sort of a last result with regard to escaping data for use in a query. The more preferable options are those native to the database you're using, if they exist.

No, you can use them right away - they are stored server-side, so you don't need to wait for a request/response loop before reading them: session_start(); $_SESSION['foo'] = 'bar'; echo $_SESSION['foo']; // 'foo' is available immediately No need to perform any special declarations. It's cookies that need to wait for a subsequent request to be available via getcookie(). Careful with your session variable naming - you may want to implement a primitive namespace, by using named arrays in $_SESSION, such as $_SESSION['auth']['username'] or $_SESSION['prefs']['boxers_or_briefs']. -mike. - michal migurski- contact info and pgp key: sf/cahttp://mike.teczno.com/contact.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I am also wondering if I need to declare all my variables one after the other or can I simply declare variables that I will be using immediately upon submission. I'm not quite sure what your question is, but here's some info. You have to call session_start() before using anything in the session. This must be called before there is any output to the browser. After the call to session_start() you can get/set/unset any session value you want at any time in the script (all of this is stored on the server). The best way to do all of this is through the $_SESSION superglobal. Use it like a normal assicative array: $_SESSION['var'] = 'value'; or: $_SESSION['array'] = array(1, 2, 3, 4); os: $_SESSION['object'] = new Object(); Everything you put in there will be available from any function without having to use the global keyword or the $GLOBALS superglobal. Note that you can't store recources in the session (at least, they can't be used as resources on subsequent requests.)
