Operating system: Linux
PHP version: 5.0.2
PHP Bug Type: Zend Engine 2 problem
Bug description: Object Destruction Order
Description:
------------
First of all. It's not a bug. It's a sugestion to give more stability to
the engine.
When the Zend Engine reaches the end of a script page it cleans up the
classes that have been created.
Nowadays it cleans up in the order the classes have been created.
I suggest that it would be a safer routine to destroy a class following a
heap of objects (first in last out).
It would help some nesting routines, not mentioning the memory
allocation.
Reproduce code:
---------------
<?
$ident = 0;
class Tag {
public $aVar;
function __construct( $pMe ) {
global $ident;
$this->aVar = $pMe;
echo
str_repeat(" ",$ident)."[".$this->aVar."]<br>";
$ident++;
}
function __destruct() {
global $ident;
$ident--;
echo
str_repeat(" ",$ident)."[/".$this->aVar."]<br>";
}
}
$v1 = new Tag("tag1");
$v2 = new Tag("tag2");
$v3 = new Tag("tag3");
echo '<br><br>';
?>
Expected result:
----------------
[tag1]
[tag2]
[tag3]
[/tag3]
[/tag2]
[/tag1]
Actual result:
--------------
[tag1]
[tag2]
[tag3]
[/tag1]
[/tag2]
[/tag3]
