This should NOT be a problem in PHP - but it is one in PHP 4. I've seen
this too and have a patch almost ready that backports the fixes done in
PHP 5.

Ain't it time to think about a fix? (Reproduced with 4.3.10 on fedora
core 2 in debug-mode)
The references created due to this bug, might be the cause my script
keeps segfaulting.
About this I've posted a report before, and will post another in the
near future. So I won't mention anything about that hear just yet.

Still exists in 4.3, but has been already fixed in both 5.x branches.

The following piece produces a similar result:
<?php
class foo {}
$a = array(new foo());
function show(&$this) { return 5; }
show($a[0]);
var_dump($a);
?>

Description:
------------
In an array, classes become classes references when I use a function
member.
Because of that, I don't copy it anymore, I just produce more pointers
to it.
(see the '&' in the var dump)
If you comment the magic line, the bug won't appear.
Tested under linux (php 4.1.2 and 4.2.3)
and windows (php 4.3.2)
Reproduce code:
---------------
<?php
class AAAAA {
var $value;
function AAAAA() {}
function show() { return 5; }
}
$A = array(new AAAAA());
$A[0]->show(); /* magic line */
$A[0]->value = 'A';
$B = $A;
$B[0]->value = 'B';
echo $A[0]->value.$B[0]->value;
echo "\n";
var_dump( $A );
?>
Expected result:
----------------
AB
array(1) {
[0]=>
object(aaaaa)(1) {
["value"]=>
string(1) "A"
}
}
Actual result:
--------------
BB
array(1) {
[0]=>
&object(aaaaa)(1) {
["value"]=>
string(1) "B"
}
}
