PHP Bug Type: Session related
Bug description: PHP 5 object references don't survive serialization
Description:
------------
Object references inside PHP5 objects are not preserved through
serialize/unserialize like traditional PHP4 references. This means they
cannot be used in session-based applications.
Reproduce code:
---------------
class Bar {}
class Foo {
var $v1;
var $v2;
function Foo() {
$this->v1 = new Bar;
$this->v2 = $this->v1;
}
}
$f = new Foo;
var_dump($f);
$g = unserialize(serialize($f));
var_dump($g);
print $s1;
Expected result:
----------------
This is what I get if I use $this->v2 = &this->$v1 instead of $this->v2 =
$this->v1:
object(foo)#1 (2) {
["v1"]=>
&object(bar)#2 (0) {
}
["v2"]=>
&object(bar)#2 (0) {
}
}
object(foo)#3 (2) {
["v1"]=>
&object(bar)#4 (0) {
}
["v2"]=>
&object(bar)#4 (0) {
}
}
Actual result:
--------------
object(foo)#1 (2) {
["v1"]=>
object(bar)#2 (0) {
}
["v2"]=>
object(bar)#2 (0) {
}
}
object(foo)#3 (2) {
["v1"]=>
object(bar)#4 (0) {
}
["v2"]=>
object(bar)#5 (0) {
}
}
