#44063 [Opn->Bgs]: RecursiveIteratorIterator needs rewind right after creation

ID: 44063 Updated by: helly@php.net Reported By: smirnov at h-type dot com -Status: Open +Status: Bogus Bug Type: SPL related -Operating System: Windows +Operating System: * PHP Version: 5.2.5 -Assigned To: +Assigned To: helly New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php Flipe, your assumption is wrong. Adding rewind to the constructor would result in a doubled call to rewind on the ArrayIterator. Now the whole Iterator collection is designed to not duplicate any calls and to be used by foreach. So you are basically missing the rewind call, which by the way all examples with while have (at least my own ones). I might however look into this again and check whether I can do something about the starting value in case of the missing rewind call on the ArrayIterator.

Reproduce code: --------------- $array = array( array('name'=>'butch', 'sex'=>'male'), array('name'=>'fido', 'sex'=>'male'), array('name'=>'girly','sex'=>'female') ); $it=new RecursiveIteratorIterator(new RecursiveArrayIterator($array)); //$it->rewind(); //The result will be as expected if uncomment this while($it->valid()){ echo $it->key().' -- '.$it->current()."\n"; $it->next(); } Expected result: ---------------- name -- butch sex -- male name -- fido sex -- male name -- girly sex -- female Actual result: -------------- 0 -- Array name -- butch sex -- male name -- fido sex -- male name -- girly sex -- female ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=44063&edit=1
