I still don't see any bug here..using references with _SESSION is not
really useful as only the value is stored..
You think it should stay as a reference?

Hello,
This code is incorrect - I must have pasted over the code after I
modified it during testing as $foobar is not a reference, but a copy.
Here is what it should be (please note that you will have to hit reload
after the first hit as session gets created on the first hit - so load
it and hit reload - and then view the output):
<?php
session_start();
echo 'Before session modifications:<br><pre>';
var_dump($_SESSION);
$_SESSION['foobar'] = 1;
$foobar =& $_SESSION['foobar'];
global $foobar;
$foobar = 3;
echo '</pre>After session modifications:<br><pre>';
var_dump($_SESSION);
?>

I get this normal output:
Before session modifications:
array(1) {
["foobar"]=>
int(1)
}
After session modifications:
array(1) {
["foobar"]=>
int(1)
}
No bug here. (using PHP 4.3.0-dev)

Hello,
I don;t think it is quote as easy as saying "Don't use global with the
autoglobal arrays.". Please read my original bug post. I went out of
my way to be very detailed so that I don't waste your time - this does
nobody any good though if you don't take the time to read it. More
specifically, this is the part I am referring to:
<ORIGNAL BUG POST>
So now you are asking that is interesting, but why would you ever want
to "global" an autoglobal. Good question! There would be no purpose
in doing this since $_SESSION is always in scope. Well, this bug
presented itself to me in an application where there was a reference to
a portion of $_SESSION. Since the application is over 5000 lines of
code, we will view a highly condensed test version of this:
<?php
session_start();
echo 'Before session modifications:<br><pre>';
var_dump($_SESSION);
$_SESSION['foobar'] = 1;
$foobar = $_SESSION['foobar'];
global $foobar;
$foobar = 3;
echo '</pre>After session modifications:<br><pre>';
var_dump($_SESSION);
?>
</ORIGNAL BUG POST>
So the bug presents itself when you "global" a reference to an array
element of an autoglobal as well. Perhaps, I should have used this as
the original code example. Please take the time to read the full bug
post.
Thank You,
Mike

Hello,
I have compiled the latest snap shot at
http://snaps.php.net/php4-latest.tar.gz. The only change I had to make
for the PHP compiling process was to update my version of curl since
the snapshot requires curl-7.10.2 (the latest stable release). It
compiled fine, I restarted the web server, and the same problem still
occurs with the same code from my original bug post.
Please let me know if you need any additional information.
Mike
