// php COOKIE設置函數立即生效，支持數組
function cookie($var, $value = '', $time = 0, $path = '', $domain = '', $s = false)
{
 $_COOKIE[var] = $value;
 if (is_array($value)) {
 foreach ($value as $k => $v) {
 setcookie($var .'['.$k.']', $v, $time, $path, $domain, $s);
 }
 } else {
 setcookie($var,$value, $time, $path, $domain, $s);
 }
}

$_COOKIE[$var] = $value;
setcookie($var,$value,$time,$path,$domain,$s);
