Re: [PHP] SESSION array problems [ANOTHER SOLUTION]
register_globals has been deprecated as of PHP6. So writing PHP code to work without global registering not just prevents variable poisoning, it also increases the life span of your scripts. I still wonder if using php_flag register_globals off in .htaccess might affect servers running PHP4 and using safe mode as in ... http://forum.mamboserver.com/showthread.php?t=44514 A yeti -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] SESSION array problems [ANOTHER SOLUTION]
Hi gang: While this may be trivial to many of you, I post this for the others. In my last problem, which was caused by register globals being ON, I wondered how I could fix this. In my specific case, the client had Register Globals ON and his host objected to turning if OFF saying that other scripts might break. After hearing that, the client was not willing to risk it. So, I looked at some of my older scripts and found I had used: ini_set( 'register_globals', '0' ); But in my last problem, neither '0' or 'off' did anything. So, I looked at the manuals again: http://www.php.net/manual/en/ini.php The manual says, I can change this directive: Entry can be set in php.ini, .htaccess or httpd.conf So, by simply adding an .htaccess file with the following -- php_flag register_globals off -- fixed the problem.

Your point is well taken, but I'm not sorting this.
True, the arrays have a common index, which is 0, 1, 2, 3 ...
[user_id] = Array
(
[0] = 6156
[1] = 7030
[2] = 656
)
[first_name] = Array
(
[0] = Diane
[1] = Fred
[2] = Helen
)
[last_name] = Array
(
[0] = Cable
[1] = Cago
[2] = Cahalan
But the data is relational, such as:
Diane Cable has user id 6156.
I collected the data like this (in a loop):
$_SESSION['user_id'][] = $value;
$_SESSION['first_name'][] = $first_name;
$_SESSION['last_name'][] = $last_name;
Doing this is fine -- the index is automatic.
I thought I could retrieve the data by using:
$num_users = count($_SESSION['user_id']); // --- this works (correct
$num_users)
for ($i = 0; $i $num_users; $i++)
{
$last_name = $_SESSION['last_name'][$i];
$first_name = $_SESSION['first_name'][$i];
echo(trtd$last_name/tdtd$first_name/td/tr); }
But that doesn't work. What's really odd is only the first loop works.
I'm thinking register_globals here. In every example you've posted,
you've used $last_name and $_SESSION['last_name'] -- but these are the
same thing if register_globals is on, and would lead to your posted
output with the single characters on the 2nd iteration and nothing after
that!
At least one posted suggestion used $first and $last rather than
$first_name and $last_name -- did you actually try with the shorter
names, or stick with your longer matching ones?

Re: [PHP] SESSION array problems [SOLVED]
Hi gang:
As strange as it may seem, but when session variables are passed to
another page (i.e., used) you cannot extract ALL OF THEM using a loop
when the variable names you are using are the same as the SESSION
index's names.
In other words, you cannot do this:
for ($i = 0; $i $num_users; $i++)
{
$last_name = $_SESSION['last_name'][$i];
$first_name = $_SESSION['first_name'][$i];
echo(p$last_name $first_name/p);
}
But you can do this:
for ($i = 0; $i $num_users; $i++)
{
$last = $_SESSION['last_name'][$i];
$first = $_SESSION['first_name'][$i];
echo(p$last $first/p);
}
See the difference?
This was a crazy one.
Now, someone show me where that is documented?

As several of us have suggested now, it's got to be register_globals.
That would make the following blocks of code equivalent:
?php
for ($i = 0; $i $num_users; $i++)
{
$last_name = $_SESSION['last_name'][$i];
$first_name = $_SESSION['first_name'][$i];
echo(p$last_name $first_name/p);
}
for ($i = 0; $i $num_users; $i++)
{
$_SESSION['last_name'] = $_SESSION['last_name'][$i];
$_SESSION['first_name'] = $_SESSION['first_name'][$i];
echo(p{$_SESSION['last_name']} {$_SESSION['first_name']}/p);
}

Me including your email address in my replies (which I will continue to do - that's what you have to pay to get my advice) affects you and you alone and is simply a result of you subscribing to this mailing list through the newsgroup rather than as a mailing list as FSM intended.

[PHP] SESSION array problems
Hi gang:
Apparently, there's something going on here that I don't understand
-- this happens far too often these days.
Here's a print_r($_SESSION); of the session arrays I'm using:
[user_id] = Array
(
[0] = 6156
[1] = 7030
[2] = 656
)
[first_name] = Array
(
[0] = Diane
[1] = Fred
[2] = Helen
)
[last_name] = Array
(
[0] = Cable
[1] = Cago
[2] = Cahalan
The following is how I tried to access the data contained in the
$_SESSION arrays:
$num_users = count($_SESSION['user_id']);
for ($i = 0; $i $num_users; $i++)
{
$last_name = $_SESSION['last_name'][$i];
$first_name = $_SESSION['first_name'][$i];
echo(p$last_name, $first_name/p);
}
The only thing that came out correct was the first echo. The
remaining echos had no values for $first_name or $last_name.
What's happening here?
Cheers,
tedd
PS: I'm open to other suggestions as to how to do this.

hi tedd,
if I may suggest this model
$_SESSION
{
[6156]
{
[first_name]= Diane
[last_name] = Cable
}
[7030]
{
[first_name]= Fred
[last_name]= Cago
}
[656]
{
[first_name]= Helen
[last_name]= Cahalan
}
}
main reason - if you sort by first or last name you will lose index.
this way is index always linked to first/last name.
foreach ($_SESSION as $key = $value)
{
echo $_SESSION[$key]['last_name'].',
'.$_SESSION[$key]['first_name'].'br';
}
didn't test it, though :-)

Your point is well taken, but I'm not sorting this.
True, the arrays have a common index, which is 0, 1, 2, 3 ...
[user_id] = Array
(
[0] = 6156
[1] = 7030
[2] = 656
)
[first_name] = Array
(
[0] = Diane
[1] = Fred
[2] = Helen
)
[last_name] = Array
(
[0] = Cable
[1] = Cago
[2] = Cahalan
But the data is relational, such as:
Diane Cable has user id 6156.
I collected the data like this (in a loop):
$_SESSION['user_id'][] = $value;
$_SESSION['first_name'][] = $first_name;
$_SESSION['last_name'][] = $last_name;
Doing this is fine -- the index is automatic.
I thought I could retrieve the data by using:
$num_users = count($_SESSION['user_id']); // --- this works
(correct $num_users)
for ($i = 0; $i $num_users; $i++)
{
$last_name = $_SESSION['last_name'][$i];
$first_name = $_SESSION['first_name'][$i];
echo(trtd$last_name/tdtd$first_name/td/tr);
}
But that doesn't work. What's really odd is only the first loop works.
PLUS, a dump of the SESSION arrays done just before the loop does
produce what's shown above. So, the data is there, I'm just not
retrieving it.
There's something here that I'm not understanding. I always seem to
have problems with Multidimensional Arrays -- I think it's my
dyslexia kicking in.

tedd

Must be something else in your code or some bad server config, because
this works great for me:
?php
session_start();
$_SESSION['user_id'][] = '6156';
$_SESSION['first_name'][] = 'Diane';
$_SESSION['last_name'][]= 'Cable';
$_SESSION['user_id'][] = '1234';
$_SESSION['first_name'][] = 'Big';
$_SESSION['last_name'][]= 'Ron';
$_SESSION['user_id'][] = '8867';
$_SESSION['first_name'][] = 'Joe';
$_SESSION['last_name'][]= 'Dirt';
$num_users = count($_SESSION['user_id']);
for ($i = 0; $i $num_users; $i++)
{
$last_name = $_SESSION['last_name'][$i];
$first_name = $_SESSION['first_name'][$i];
echo(p$last_name, $first_name/p);
}
?
Outputs this:
Cable, Diane
Ron, Big
Dirt, Joe

I just copied your code, created your sessions and - it works fine.
http://afan.net/tedd.php
code:
?php
session_start();
$_SESSION['user_id'] = array(6156, 7030, 656);
$_SESSION['first_name'] = array('Diane', 'Fred', 'Helen');
$_SESSION['last_name'] = array('Cable', 'Cago', 'Cahalan');
echo 'pre';
print_r($_SESSION);
$num_users = count($_SESSION['user_id']); // --- this works (correct
$num_users)
echo ?: .$num_users.'brtable border=1';
for ($i = 0; $i $num_users; $i++)
{
$last_name = $_SESSION['last_name'][$i];
$first_name = $_SESSION['first_name'][$i];
echo(trtd$last_name/tdtd$first_name/td/tr);
}
echo '/table';
I think there is something outside your code.

I still see an index mixing issue here for you. However, on a side note, why
don't you create user objects and then just stick the object(s) in the
$_SESSION array? Then just while() loop the session and pull the objects out.

Why don't you echo what you are trying to access for each loop
for ($i = 0; $i $num_users; $i++)
{
print_r($_SESSION['last_name'][$i]);
print_r($_SESSION['first_name'][$i]);
}
Does the above return to you what you would expect?
An alternate to what you are doing here would be this.
foreach ( $_SESSION['user_id'] AS $i=$id)
{
print_r($id);
print_r($_SESSION['last_name'][$i]);
print_r($_SESSION['first_name'][$i]);
}
How about this?

[PHP] SESSION Array problem - possibly different PHP versions?
Hi All, I have a problem that only occurs on our live server and not our local server. It works fine locally. Basically I am using a session array to store values of product colours. A user can add colours to the session array. The session is defined as follows: $_SESSION['color'][$counter] = $color; Obviously the first time we validate and the $counter is set to 0. When more colours are added the $counter variable increments and should increment the value of the array. The colours are added through a popup window. Before I open the popup window I print_r($_SESSION['color']) to view the contents of the array and make sure that they are valid and it is an array. Output is as follows: [color] = Array ( [0] = #339933 [1] = #00 ) etc... Then once the popup opens I do the same print_r And it now shows: [color] = #339933 There fore it isn't an array of colors within the session array. How can PHP change this? Also the strange thing is that locally it works fine but not live. So I am guessing that there is a problem with a certain version of PHP? Also Im not sure what else could be causing this problem? Any ideas or hints would be appreciated.

From where is the color data coming in to the script, a database?
Check to make sure that the array is being populated. Also, you're
not attempting to pass the session from your dev box to your live box,
are you?

Also, you're not attempting to pass the session from your dev box to your live box, are you? Hi Daniel, thanks for the reply. The system works as follows. There is a colour picker, when a user clicks on a colour then it opens a popup window with the color set as a GET variable. They can then enter the price per colour etc... once done, they save it. It then saves the details to a session. The user then closes the window and it refreshes the parent page which has the colour picker and a listing of selected colours already choosen, after the refresh it shows the array values (print_r) and is correct the first time: [color] = Array ( [0] = #339933 Then if they do the same procedure again, once the popup opens it shows the session variable as: [color] = #339933 But nothing has been done to the SESSION variables since the save, so somehow between the the click and the popup opening something strange is happening. Like I mentioned it works on a local laptop as well as our local server so its strange, I have tried many times closing the browser to ensure all sessions are cleared.

Is there a way to count/output (FOR EACH?) a set of session arrays like
if (is_array($_SESSION['results'])) echo 'number of results is ',

foreach ($_SESSION['results'] as $number = $data) {
echo result number $number contains:;

It may or may not be something you want, but I doubt it will have any
affect whatsoever on your posted problem.
Actually, I think anywhere that somebody thinks they need
ignore_user_abort, they probably should re-structure the application
to handle the long-running process in a cron job or some other
asynchronous manner, rather than try to keep a script running tied to
an HTTP connection that isn't useful anymore.
In other words: Move the long-running slow heavy lifting computation
OUT of the web page generation part, so that your user gets a web page
super fast in the first place, and so the long-running part can get
done later, when the user isn't stuck waiting around for it.

called Web 2.0 now. :-)

Hello,
Thank you for the reply.
Interesting function. I have not heard of that one previously. I've
read the manual pages for it.If I understand
ignore_user_abort(TRUE)...you are thinking that maybe the user is
being
disconnected (using stop button or having ISP issues) prior to the
script finishing and therefore the script does not have a chance to
create the array? I'm wondering if that would be true, since later in
the same script, it generates an email to inform me someone's
submission
was lost because the array did not exist. I'm confused how it could
stop executing the middle of the script (step 4a and 5 below) but yet
execute the end of the script (the final step in the code below)? I
was
first made aware of this issue because of the email, so I think the
end
of the script is executing.
Thanks,

Hello,
The site I'm working on works like this...
Requires a login that uses sessions to remember username and
email
address. Upon being verified, the user is presented with a page
that displays several questions regarding their background. Upon
submitting the background page, a script checks to make sure all
background questions were answered. If not, the page is
redisplayed with a warning to answer all questions. If they are
all present, a second page is displayed asking about a specific
topic. Submitting the second page calls up the code provided
below.
In reading the www.php.net/manual/en/ref.session.php page, I'd
like
to point out we do not use cookies. The session id is propagated
in the URL (although it's not visible in the URL bar). Also,
session.gc_maxlifetime is set to 5400. We are using PHP 4.3.4.
Not very often, but once in a while, I'll get an email warning me
that a submission was denied because $_SESSION['Q'] is empty.
I'm
wondering, hoping and/or praying that someone out there can look
at
this small script and let me know if I'm doing something wrong
with
the built in function array_pop, perhaps I don't understand
sessions at all or perhaps it is a server issue. It's very
confusing because other session variables (name and email from
the
login page) are not emptied, just $_SESSION['Q'].
Here's my code with some documentation:
?php
/*
$_SESSION['startQA'] contains 11 elements and is generated by a
previous page in the site.
Once the visitor clicks the page two submit button, the above
SESSION variable comes into play again.
This script takes that array of elements and does the following:
1. Assign session array to local array
2. Removes the last elemental value using array_pop
3. Removes the last elemental value using array_pop
4. Assign local variable the value of the a POST element
4a. Create a new session array and populates the first element
equal to POST element
5. Runs through and populates the remaining 9 elements
5a. Total of 10 elements are now populated, 0 thru 9
6. Double checks the existence of each element
6a. if an element is missing, email me a warning and end program

Something is very odd here...
Unless the session data is being passed as an INPUT TYPE=hidden in a
FORM, it has to be in the URL to work.
It should be visible in the URL bar if it's in the URL.
Though, obviously, the thing works, so it's not your problem here...
It's just something you should investigate for your own learning
experience, rather than to solve your problem today.
I apologize, I should have been more clear, and I should have thought a
little more before describing the situation. Users navigate from page
to page by use of a form method=POST submit button. They do not use
a href links to go from page to page.

This is the source of your troubles.
Step 4a is pointless.
Try this in a small test file:
?php
$anything['Q'] = 'x';
$anything['Q'][1] = 'y;
print_r($anything);
?
Per your suggestions, here's a couple of tests I ran and the results I
received:
?php
session_start();
$testVariable = 'a';
$_SESSION['test'] = array($testVariable);
$_SESSION['test'][1] = 'b';
print_r($_SESSION['test']);
?
Results:
Array ( [0] = a [1] = b )
(desired result, basically what I'm using now)
?php
session_start();
$testVariable = 'a';
$_SESSION['test'] = $testVariable;
$_SESSION['test'][1] = 'b';
print_r($_SESSION['test']);
?
Results:
ab
(treats it like a string instead of an array, undesired result)
?php
session_start();
$testVariable = 'a';
$_SESSION['test'][0] = array($testVariable);
$_SESSION['test'][1] = 'b';
print_r($_SESSION['test']);
?
Results:
Array ( [0] = Array ( [0] = a ) [1] = b )
(creates multi-dimensional array, undesired result)
?php
session_start();
$testVariable = '1';
$_SESSION['test'][0] = $testVariable;
$_SESSION['test'][1] = '2';
print_r($_SESSION['test']);
?
Results:
Array ( [0] = 1 [1] = 2 )
(desired result)
According to these tests, I could use the first example or the last
example to achieve the desired results.
//test for existense of session array elements
if ( ($_SESSION['Q'][0] == ) OR ($_SESSION['Q'][1] == ) OR
($_SESSION['Q'][2] == ) OR ($_SESSION['Q'][3] == ) OR
($_SESSION['Q'][4] == ) OR ($_SESSION['Q'][5] == ) OR

SEND ME AN ERROR EMAIL
It might be a Good Idea for this error email to dump out ALL of
$_SESSION['Q'] as well as all the variables you think are involved in
your problem.
You would then be able to backtrack and debug this issue in the future.
I agree. I actually realized this yesterday after I sent my email to
the list. I'm in the process of adjusting the code to include variables
in the email. Thank you for the suggestion(s). They are greatly
appreciated.
At this point, here's my logical thinking
1. Occassionaly, the background information session array is missing one
or more elements thus an email is generated and the script ends immediately.
2. In the email portion of the script, which is after the array element
check, I call other session variables (username, email address) and they
are present.
3. Given the above information, I'm inclined to believe that it's got
something to do with just the background information session array.
3a. Perhaps array_pop is the problem, it works differently then I
thought?.?.
3b. Perhaps the way I construct the session array corrupts it (using a
for loop)?.?.
4. Perhaps session variables are not really intended to contain arrays?.?.
5. I'm not sure if any user interactions (web accelerator, ISP issues or
Forward/Back/Reload browser buttons) would cause such an issue?.?.
Looking at the above list, I can only deal with item 3. I could change
my session array code to populate it like this:
$_SESSION['Q'][0] = $testVersion;
$_SESSION['Q'][1] = $thisQarray[0];
$_SESSION['Q'][2] = $thisQarray[1];
$_SESSION['Q'][3] = $thisQarray[2];
$_SESSION['Q'][4] = $thisQarray[3];
$_SESSION['Q'][5] = $thisQarray[4];
$_SESSION['Q'][6] = $thisQarray[5];
$_SESSION['Q'][7] = $thisQarray[6];
$_SESSION['Q'][8] = $thisQarray[7];
$_SESSION['Q'][9] = $thisQarray[8];
I'm really at a loss and have no idea what else to try other then the
above code.
Thanks,
R

It's been my experience that user interaction can really corrupt data. I would hate to force a script to finish if the user caused issues with the expected data. Perhaps everyone uses it in this manner in default (with data checks) and my point is moot.

Re: [PHP] Session Array Disappears
Hello,
Thank you for the reply.
Interesting function. I have not heard of that one previously. I've
read the manual pages for it.If I understand
ignore_user_abort(TRUE)...you are thinking that maybe the user is being
disconnected (using stop button or having ISP issues) prior to the
script finishing and therefore the script does not have a chance to
create the array? I'm wondering if that would be true, since later in
the same script, it generates an email to inform me someone's submission
was lost because the array did not exist. I'm confused how it could
stop executing the middle of the script (step 4a and 5 below) but yet
execute the end of the script (the final step in the code below)? I was
first made aware of this issue because of the email, so I think the end
of the script is executing.
Thanks,
R

add a ignore_user_abort(TRUE) first thing in your code.
Hello,
The site I'm working on works like this...
Requires a login that uses sessions to remember username and email
address. Upon being verified, the user is presented with a page
that displays several questions regarding their background. Upon
submitting the background page, a script checks to make sure all
background questions were answered. If not, the page is
redisplayed with a warning to answer all questions. If they are
all present, a second page is displayed asking about a specific
topic. Submitting the second page calls up the code provided below.
In reading the www.php.net/manual/en/ref.session.php page, I'd like
to point out we do not use cookies. The session id is propagated
in the URL (although it's not visible in the URL bar). Also,
session.gc_maxlifetime is set to 5400. We are using PHP 4.3.4.
Not very often, but once in a while, I'll get an email warning me
that a submission was denied because $_SESSION['Q'] is empty. I'm
wondering, hoping and/or praying that someone out there can look at
this small script and let me know if I'm doing something wrong with
the built in function array_pop, perhaps I don't understand
sessions at all or perhaps it is a server issue. It's very
confusing because other session variables (name and email from the
login page) are not emptied, just $_SESSION['Q'].
Here's my code with some documentation:
?php
/*
$_SESSION['startQA'] contains 11 elements and is generated by a
previous page in the site.
Once the visitor clicks the page two submit button, the above
SESSION variable comes into play again.
This script takes that array of elements and does the following:
1. Assign session array to local array
2. Removes the last elemental value using array_pop
3. Removes the last elemental value using array_pop
4. Assign local variable the value of the a POST element
4a. Create a new session array and populates the first element
equal to POST element
5. Runs through and populates the remaining 9 elements
5a. Total of 10 elements are now populated, 0 thru 9

Something is very odd here...
Unless the session data is being passed as an INPUT TYPE=hidden in a
FORM, it has to be in the URL to work.
It should be visible in the URL bar if it's in the URL.
Though, obviously, the thing works, so it's not your problem here...
It's just something you should investigate for your own learning
experience, rather than to solve your problem today.

This is the source of your troubles.
Step 4a is pointless.
Try this in a small test file:
?php
$anything['Q'] = 'x';
$anything['Q'][1] = 'y;
print_r($anything);
?
You will not see an 'x' in the output anywhere.
$anything cannot be a 1-dimensional array and a 2-dimensional array at
the same time.
You'll need to store the data from Step 4a in some special 2-D place
within $_SESSION['Q']
It looks from your code that perhaps $_SESSION['Q'][0] would be an
ideal candidate, as you are using $newBGQcounter+1 as an index, and
$newBGQcounter starts at 0 and goes to the size of some other array.
So you are using 1, 2, 3, 4, ... for the $thisQarray, and you can cram
the $testVersion into index 0.
On the other hand, it would probably be MUCH better to not try to cram
$testVersion and $thisQarray into the same data structure.
Maybe what you SHOULD be doing is more like:
$_SESSION['testVersion'] = $testVersion;
$_SESSION['thisQarray'] = $thisQarray;
Then you won't be confusing yourself with what's what in the SESSION
data because the names will match up.
There is no need to iterate through an array just to copy it into
$_SESSION -- you'll have the indices running from 0 instead of from 1,
but you really should just get used to that, and if you ever need to
print the index out for a human, only change the numbering on output,
not on your internal data structures.
//test for existense of session array elements
if ( ($_SESSION['Q'][0] == ) OR ($_SESSION['Q'][1] == ) OR
($_SESSION['Q'][2] == ) OR ($_SESSION['Q'][3] == ) OR
($_SESSION['Q'][4] == ) OR ($_SESSION['Q'][5] == ) OR
($_SESSION['Q'][6] == ) OR ($_SESSION['Q'][7] == ) OR
($_SESSION['Q'][8] == ) OR ($_SESSION['Q'][9] == ) )
{
SEND ME AN ERROR EMAIL
It might be a Good Idea for this error email to dump out ALL of
$_SESSION['Q'] as well as all the variables you think are involved in
your problem.
You would then be able to backtrack and debug this issue in the future.

Re: [PHP] Session Array Disappears
I'm thinking the guy who suggested ignore_user_abort(TRUE) is just
doing Voodoo Programming :-)
It may or may not be something you want, but I doubt it will have any
affect whatsoever on your posted problem.
Actually, I think anywhere that somebody thinks they need
ignore_user_abort, they probably should re-structure the application
to handle the long-running process in a cron job or some other
asynchronous manner, rather than try to keep a script running tied to
an HTTP connection that isn't useful anymore.
In other words: Move the long-running slow heavy lifting computation
OUT of the web page generation part, so that your user gets a web page
super fast in the first place, and so the long-running part can get
done later, when the user isn't stuck waiting around for it.
Your basic Human Interface principle, which is apparently going to be
called Web 2.0 now. :-)

[PHP] Session Array using array_pop and array_unshift
Hello, I have an application that occasionally drops a session array element value. Data from the form... $_POST['firstName']; $_POST['lastName']; $_POST['phone']; $_POST['email']; $_POST['cell']; When the form is submitted, the POST variables are checked to make sure they each contain a value. If not, the form is redisplayed and the user is alerted to the missing data. The next step in the process places the data into an array and then assigns the array to a session variable... $userData = array ($_POST['firstName'], $_POST['lastName'], $_POST['phone'], $_POST['email'], $_POST['cell']); $_SESSION['userData'] = $userData; The user then visits some other pages and fills out some more data. At one point, it is necessary to remove the last two elements from the session array. This is achieved by using array_pop... $cellPhone = array_pop($_SESSION['userData']); $emailAddress = array_pop($_SESSION['userData']); And then it is necessary to add a different variable to the beginning of the session array... $userCleared = ok; array_unshift($_SESSION['userData'], $userCleared); Finally, the data is checked again to make sure values exist. At this point, occasionally, one of the element values of the session array is missing. It's never the same one. It seems that, at random, one of the elemental values just goes away. The others are still there. If an element is missing, I receive an email alerting me to this fact. I can think of other ways to handle all of this data, but my question is this...would the current code cause elements to loose their value? Would using a session array AND the array_pop or array_unshift cause this to happen? Has anyone else experienced this sort of occasional anomaly?

On Wed, May 11, 2005 4:46 pm, Webmaster said: I have an application that occasionally drops a session array element value. $_SESSION['userData'] = $userData; this to happen? Has anyone else experienced this sort of occasional anomaly? YES! Granted, in my case, it was a short-lived buglet in PHP, and it was more predictable because I was doing the same thing every time, but... Basically, what was happening in MY case was this: $foo = $_SESSION['foo']; This was putting a string reference (which doesn't even exist as a data type in PHP, but that's what it was in reality) into $foo. Then, later, in other processing, I might do: $foo = 'some other value than was was in $foo'; And, POOF! my value in $_SESSION['foo'] was altered! Because $foo was a string reference being passed back from the PHP code that pulled data out of $_SESSION. I filed a bug report at http://bugs.php.net, and it's labeled as fixed in CVS Short term, I just stopped re-using $foo as a variable name. It's entirely POSSIBLE that you have something similar going on. One tell-tale was that doing a var_dump($_SESSION) or var_dump($foo) would show something not un-like: (string X) foo data where X is the string length, instead of just: (string X) foo data The tell-tale presence of is what made me realize that I was somehow getting a string reference and that was messing with my data when I re-used variables. The annoying thing was that this made scrubbing my $_SESSION data difficult -- and I had people telling me that I should be copying stuff out of $_SESSION, but on a shared server, I don't trust $_SESSION data! So I want to copy it out to $foo, and do, say, a regex on it, and compare the result to the original $_SESSION['foo'] and if they don't match, I consider that data hacked/invalid, because I know it's supposed to be the same before/after this Regex. Yet, if the string is a reference, well, then, the Regex applied to the reference was getting applied to the $_SESSION element... Anyway, make a long story short, it was quite confusing and more than a little annoying to be trying to scrub data that was always a reference and kept changing out from under me when I used it. This may NOT be what's happening to you... Or it might be another manifestation of the same buglet. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hey, I am getting something like this: input type=checkbox name='id[loco package]' value=1 I will be getting upto 5 of the above values, Thanks to John Holmes (from this list) I know how to enter it into the database but how do i create a session with the above? The reason why i want to do this is, 1)user picks upto 5 packages to save to his account (done) 2)if the user is already logged in then the insert query is run and all goes well (done) 3) if the user has not logged in then it should be saved as a session and he should be presented with the login screen, after he logs in the insert query should be run from the session data.without the user re-picking the packages(not done) I was able to do the above (point 3) when i was working with a simple array (eg: id[]=1) but am unable to do so when working with the newer one (id[something]=1) Any help appreciated.

you can assign any type of data, just like a regular hash.

[PHP] Session Array Problems - Please Help
I'm having issues registering and then updating a value for specific items
in an array. I've read through the manual and MARC but I can't seem to find
the right answer. Here's what I'm trying to do...
Basic Backgroung: This is a view cart page. Depending on products that
they have selected I pull information from a MySQL database to give details
about their product. To do so I have set up a loop (duh) and on each pass
of the loop I add information to the session array. Here's the code...it
will make more sense...
First...I clean the arrays so that I don't have conflicting data...this is
done first thing on the page after session_start();
session_start();
session_register('subtotal');
session_unregister('kitem');
session_unregister('kquan');
session_unregister('kscale');
session_unregister('kdetail');
session_unregister('kdriver');
session_unregister('ksponsor');
session_unregister('kcompany');
session_unregister('kprice');
Then comes the loop which adds data to the now empty arrays...
for ($index = 0; $index $indexLimit; $index++)
//connect and query MySQL database
include (connect.php);
$result = mysql_query(SELECT * FROM ar
LEFT JOIN company on ar.company_id=company.company_id
LEFT JOIN scale on ar.scale_id=scale.scale_id
WHERE ar.item_number = '.$i[$index].'\n);
//sort through results
if ($myrow = mysql_fetch_array($result))
{
do
{
if ($quan != 0 $quan != $quan != 0)
{
//the following vars will be used on the order form as hidden
fields.
$kitem[$index] = $myrow[item_number];
$kquan[$index] = $quan;
$kscale[$index] = $myrow[size];
$kdetail[$index] = $myrow[details];
$kdriver[$index] = $myrow[driver_name];
$ksponsor[$index] = $myrow[sponsor];
$kcompany[$index] = $myrow[value];
$kprice [$index] = $myrow[price];
}
}
while($myrow = mysql_fetch_array($result));
}
And then finally I reset my session variables (arrays) like this...
session_register('kitem');
session_register('kquan');
session_register('kscale');
session_register('kdetail');
session_register('kdriver');
session_register('ksponsor');
session_register('kcompany');
session_register('kprice');
I get mixed and varied results...usually the items show up twice or don't
show up at all. Please help if you can see anything that is being done
wrong. Thanks...

$myArray[]=array(id=$newStuff[myId],name=$newStuff[name]);
}
### mainPage.php ###

$myArray=array();
session_register(myArray);
// add some stuff to myArray here to highlight the prob
$myArray[]=array(id=1,name=gabby);
$myArray[]=array(id=2,name=marla);
..
// if conditions meet

Now on first call to addToMyArray()
I have three elements two that I added directly
and one via the function call.
Now if the function gets called again there is still
only 3 elements .. two that I added directly and the
third one from the latest function call.
The element from the first call has simply vanished !!!
And that's my problem, why is the element vanishing ???
Thanx,
Christian
