This bug has been fixed in CVS. Snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. Thank you for the report, and for helping us make PHP better. The mechanism of __clone() was changed to solve such problems. To clone an object you should now use clone $obj; It will create a replica of $obj and call $replica->__clone() if available. No more need for $that because you have all the info replicated already Calling the parent __clone() can be done by doing parent::__clone() Previous Comments: ------------------------------------------------------------------------ [2004-01-05 09:20:05] alex_boyer at hotmail dot com i mean that $that is not available in parent class A (but IT IS available in class B) ------------------------------------------------------------------------ [2004-01-05 09:17:14] alex_boyer at hotmail dot com Description: ------------ $that is not available in parent class B (uncomment code in class A you will see it). So it is not possible to clone class in a recursive way. Reproduce code: --------------- class A { public $a; function __clone(){ //if( $that === null ) die('$that is null'); $this->a = $that->a; } } class B extends A { public $b; function __clone(){ parent::__clone(); $this->b = $that->b; } } $b = new B(); $b->a = 'AAA'; $b->b = 'BBB'; $clone = $b->__clone(); print_r($clone); Expected result: ---------------- B Object ( [b] => BBB [a] => AAA ) Actual result: -------------- B Object ( [b] => BBB [a] => ) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=26794&edit=1
