Subject: php4: foreach() doesn't issue an error when a variable other than of

Severity: minor
From: http://nl3.php.net/foreach:
"(...) foreach works only on arrays, and will issue an error when you
try to use it on a variable with a different data type or an
uninitialized variable. (...)"
Well, on my Debian-testing server, PHP does not issue a warning when I
pass a var to foreach which isn't an array.
For example the following code will not output a warning with
error_reporting(EALL):
$res = NULL;
foreach ($res as $key => $value) {
echo $key . "<br />";
}
It DOES generate a warning on my W32-machine with PHP 4.3.11 installed.
To circumvent the warning on W32 I have to write the following code:
$res = NULL;
if (!is_null($res)) {
foreach ($res as $key => $value) {
echo $key . "<br />";
}
}
And this should be done on Debian too.
Regards,
Patrick
