The first execution of the file below produces the expected output:

Clicking on the Submit button outputs:

$_POST array contains:

Why don't I see one of the values from the select item?

Your foreach loop isn't going to print what _you're_ expecting.
foreach ( $_POST as $key => $value ) {
echo ( $value . "<br />" );
}
but print_r() would be much easier...
echo ( "<pre>" );
print_r ( $_POST );
echo ( "</pre>" );
