--TEST--
Temporary array expressions can be iterated by reference
--FILE--
<?php

$a = 'a';
$b = 'b';

foreach ([&$a, &$b] as &$value) {
    $value .= '-foo';
}

var_dump($a, $b);

?>
--EXPECT--
string(5) "a-foo"
string(5) "b-foo"
Remove reference restrictions from foreach foreach only allowed variables to be traversed by reference. This never really made sense because a) Expressions like array(&$a, &$b) can be meaningfully iterated by-ref b) Function calls can return by-ref (so they can also be meaningfully iterated) c) Iterators could at least in theory also be iterated by-ref (not sure if any iterator makes use of this) With by-ref generators the restriction makes even less sense, so I removed it altogether. 2012-07-22 12:33:25 +00:00			`--TEST--`
