Bug #65135 [Com]: Support for non-scalar keys in foreach() does not work with SplObjectStorage

Edit report at https://bugs.php.net/bug.php?id=65135&edit=1 ID: 65135 Comment by: nikic@php.net Reported by: sebastian@php.net Summary: Support for non-scalar keys in foreach() does not work with SplObjectStorage Status: Assigned Type: Bug Package: SPL related Operating System: Irrelevant PHP Version: 5.5.0 Assigned To: nikic Block user comment: N Private report: N New Comment: The RFC only adds the ability to have non-scalar keys. It does not change the behavior of any of our existing iterators. I don't think we can change the SplObjectStorage behavior as it would constitute a BC break (all current loops would break.) Previous Comments: ------------------------------------------------------------------------ [2013-06-26 16:09:58] sebastian@php.net Description: ------------ Quoting from https://wiki.php.net/rfc/foreach-non-scalar-keys // NOT possible foreach ($objectStore as $key => $value) { // ... } // Instead you have to use foreach ($objectStore as $key) { $value = $objectStore[$key]; // ... } This suggests that it would work after the proposed changes. However, in PHP 5.5 (for which the RFC was accepted) this still does not work. Test script: --------------- <?php $o = new SplObjectStorage; $o->attach(new DateTime, new StdClass); foreach ($o as $key => $value) { var_dump($key); var_dump($value); } Expected result: ---------------- class DateTime#2 (3) { public $date => string(19) "2013-06-26 18:04:30" public $timezone_type => int(3) public $timezone => string(13) "Europe/Berlin" } class stdClass#3 (0) { } Actual result: -------------- int(0) class DateTime#2 (3) { public $date => string(19) "2013-06-26 18:03:24" public $timezone_type => int(3) public $timezone => string(13) "Europe/Berlin" } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=65135&edit=1
