Previous Comments: ------------------------------------------------------------------------ [2005-02-01 11:21:14] rrichards@php.net Please try using this CVS snapshot: http://snaps.php.net/php5-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php5.0-win32-latest.zip I believe this was a dom problem whiich was already fixed in CVS ------------------------------------------------------------------------ [2005-01-27 13:14:08] marek dot raida at oskar dot cz I forgot to mention that in PHP 5.0.2 everything works correctly... ------------------------------------------------------------------------ [2005-01-27 13:10:22] marek dot raida at oskar dot cz Description: ------------ When references between more objects, and on of objects is extended from domDocument, has reference to it caller object and use its property in vsprinf, reference to orignal object is destroyed or wrongly managed by garbageCollector... Really confusing -> could be workarounded by calling method of domDocument extended object from outside of referenced object... Reproduce code: --------------- <?php class a { public $a = array(1,2,3); function aa($b){ $b->bb(); } } class b extends domDocument { public $a = NULL; function bb(){ $x = vsprintf('www %s www %s www %s www', $this->a->a) ; } } class x { public $a = null; public $b = null; function __construct() { $this->a = new a(); $this->b = new b(); $this->b->a = $this->a; var_dump('Object a',$this->a, 'Object b',$this->b); $this->a->aa($this->b); var_dump('Object a',$this->a, 'Object b',$this->b); } } $x = new x(); ?> Expected result: ---------------- string(8) "Object a" object(a)#2 (1) { ["a"]=> array(3) { [0]=> int(1) [1]=> int(2) [2]=> int(3) } } string(8) "Object b" object(b)#3 (1) { ["a"]=> object(a)#2 (1) { ["a"]=> array(3) { [0]=> int(1) [1]=> int(2) [2]=> int(3) } } } string(8) "Object a" <<< RIGHT object(a)#2 (1) { ["a"]=> array(3) { [0]=> int(1) [1]=> int(2) [2]=> int(3) } } string(8) "Object b" object(b)#3 (1) { ["a"]=> object(a)#2 (1) { ["a"]=> array(3) { [0]=> int(1) [1]=> int(2) [2]=> int(3) } } } Actual result: -------------- string(8) "Object a" object(a)#2 (1) { ["a"]=> array(3) { [0]=> int(1) [1]=> int(2) [2]=> int(3) } } string(8) "Object b" object(b)#3 (1) { ["a"]=> object(a)#2 (1) { ["a"]=> array(3) { [0]=> int(1) [1]=> int(2) [2]=> int(3) } } } string(8) "Object a" string(8) "Object a" <<< WRONG string(8) "Object b" object(b)#3 (1) { ["a"]=> string(8) "Object a" } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=31721&edit=1
