Bug #61505 [NEW]: Wrong destructors order
From:
Operating system: Ubuntu
PHP version: 5.3.10
Package: Class/Object related
Bug Type: Bug
Bug description:Wrong destructors order
Description:
------------
followed: https://bugs.php.net/bug.php?id=36759
They told that fixed in 5.2*, but its wrong! Reprodused in 5.3.2
Destructors on allocated objects should be called in reverse order:
$a = new world();
$b = new human();
== Shold be called as:
world->__construct();
human->__construct();
human->__destruct();
world->__destruct();
== Now its calling as:
world->__construct();
human->__construct();
world->__destruct(); // now people, cars and other exists without world.
wtf??
human->__destruct();
== Why i think current way its wrong:
When we creating object $b, we expecting that object $a exists. And while
lifetime $b, object $a should be exist. Even $b dying, $a should be
exists.
We expect in $a that $b may be not exist, but we should`t check in all
methods
of $b 'is $a exist'.
Destructor its not exception and should be executed right.
== Some simular reports:
https://bugs.php.net/bug.php?id=38572
https://bugs.php.net/bug.php?id=29032 (if we
imagine that $SESSION = new
bla_bla(), before our code)
Test script:
---------------
class screen
{
public $screen;
public function __construct()
{
echo "screen construct<br>";
$text->screen = "";
}
public function Write( $text )
{
echo "writed to screen $text<br>";
$this->screen .= $text;
}
public function __destruct()
{
echo "screen destruct<br>";
echo $this->screen;
}
}
$A = new screen();
class dummy
{
public function __constuct()
{
echo "dummy constuct<br>";
}
public function __destuct()
{
echo "dummy destruct<br>";
global $A;
$A->Write("Dummy: I`m dying!<br>");
// or $A->DoVeryImportantActionBeforeDie($bla, $bla1);
}
}
$B = new dummy();
Expected result:
----------------
screen construct
dummy constuct
writed to screen Dummy: I`m dying!
screen destruct
Dummy: I`m dying!
Actual result:
--------------
screen construct
dummy constuct
screen destruct
Fatal error: Call to a member function Write() on a non-object in ...
