Any chance of this getting into RC2?

See also bug #27964 (a bit different case but same errors :)

Jesus. Sometimes I reduce the test case too far. :)

$a = array('foo', 'bar');

foreach ($a as &$value) {
    $value = strtoupper($value);
}

print_r($a);

$a should have FOO and BAR, as it works okay if you do:

foreach ($a as $k => &$value) {
    $value = strtoupper($value);
}

But PHP gives an error on the first example w/o my 
patch.

(At least I hope it still does, I need to recompile PHP 
to triple check.)

your example doesn't have any references in it..? (and it works fine
when I replace the last ) with } :)

Description:
------------
In PHP 5, foreach() allows you to iterate over values by 
reference. This does not work when you do foreach($array 
as $value) instead of foreach($array as $key => $value).

I believe this patch fixes the problem, but someone 
should *really* double check it. :)

foreach_by_reference.txt

Reproduce code:
---------------
php -r '$array = array(); foreach($array as $value) {)'

Expected result:
----------------
Nothing.

Actual result:
--------------
PHP Fatal error:  Key element cannot be a reference in 
Command line code on line 1
