When used on a scalar or unset value, reset() spews warning messages. This is often a problem when accessing arrays generated from HTML form input data: these are scalar or unset if the user didn't enter sufficient information.

You can silence these error messages by prefixing an @ (at sign) to reset(), but it is better style to protect your reset() and the following array traversal with an if (isset()). Example code:

if (isset($form_array)) {
reset($form_array);
while (list($k, $v) = each($form_array) {
do_something($k, $v);
}
}
