Bug Type: Output Control
Operating System: win xp
PHP Version: 5.2CVS-2007-12-14 (snap)
New Comment:
Documentation says:
"When assigning an already created instance of a class to a new
variable, the new variable will access the same instance as the object
that was assigned. This behaviour is the same when passing instances to
a function."
Using PHP 5.3.0-dev (cli) (built: Dec 17 2007 10:53:40):
<?php
$obj = new stdClass;
$a = $obj;
unset($obj);
var_dump($a, $obj);
?>
Output:
object(stdClass)#1 (0) {
}
NULL

Clarifying example:
<?php
class foo {
static $foo = array();
static function test($obj) {
self::$foo[] = $obj;
}
}
class bar {
public function __construct() {
foo::test($this);
}
}
$a = new bar;
unset($a);
var_dump(foo::$foo); // He expects empty array
?>
