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

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.)

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"
}
