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. :)

php -r '$array = array(); foreach($array as $value) {)'
Expected result:

Nothing.
