New Comment:
PHP5 always pass and assign objects by reference.
You should set "zend.ze1_compatibility_mode=1" if you like PHP4
behavior.

ATTENTION: This does NOT happen with PHP_4_4 !!
Simplified example:
<?php
class something {
public $val = 0;
}
function pass_by_value($value) {
$value->val = 1;
}
$object = new something;
var_dump($object);
pass_by_value($object);
var_dump($object);
?>
Expected result:
----------------
int(0)
int(0)
Actual result:
--------------
int(0)
int(1)

Description:
------------
See reproduce code.
php.ini is stock / no changes.
Reproduce code:
---------------
<?php
// a class that does nothing
class something{
function nothing(){
}
}
// a pass-by-value function that modifies a member's member
function pass_by_value($value){
$value->member->val = 1;
}
// create a something with a member something
$object = new something;
$object->member = new something;
// call nothing, then call pass_by_value and print results
$object->member->nothing();
echo "member->val should be empty!\n";
pass_by_value($object);
print_r($object);
?>
Expected result:
----------------
$object->member should be empty
Actual result:
--------------
$object->member->val == 1
