Yes, you'll need the reset() there if you're looping through the
$HTTP_POST_VARS array more than once. However:
I take it that you were trying something like
echo $HTTP_POST_VARS[0];
? If so, you will indeed get the output 'array' if element 0 is an
array. As someone suggested, you can use the print_r() or var_dump()
functions (print_r, I think, is PHP4 only) to display it. You can
also do something like
...
if (is_array($HTTP_POST_VARS[0])) {
while (list($k,$v)=each($HTTP_POST_VARS[0])) {
echo '$HTTP_POST_VARS[0]', "[$k] = $v<br>";
}
} else {
echo '$HTTP_POST_VARS[0] = ', $HTTP_POST_VARS[0];
}
...
In PHP3, POST/GET elements could only be one dimensional arrays, at
most. In PHP4, though, these can have 2+ dimensions, so for maximum
generality you'd have to have somewhat more complex code than this.
