php post遍历问题

print_r($_REQUEST);
Copy after login

取到的值是
Array<br />
(<br />
    [c] => pay2<br />
    [cart] => 1<br />
    [itemid] => Array<br />
        (<br />
            [0] => 103<br />
            [1] => 104<br />
            [2] => 105<br />
            [3] => 106<br />
        )<br />
<br />
    [PHPSESSID] => rdkrfasknosmg58o1r1d9i6pf5<br />
)
Copy after login


<br />
<br />
foreach ($_REQUEST as $key => $value) <br />
{<br />
    echo "Key: $key; Value: $value<br />\n";<br />
}<br />
Copy after login
遍历不能遍历出itemid ,如何才能遍历成1,2,3这样


------解决方案--------------------
foreach ($_REQUEST as $key => $value) 
{
    if(is_array($value)) $value = join(',', $value);
    echo "Key: $key; Value: $value
\n";
}
