I am converting the array into cookie by php serialize function 

```
$PromoteProductArray = array("PromoteuserId"=>$PromoteuserId,
"PromoteProductId"=>$PromoteProductId,
"PromoteBrandId"=>$PromoteBrandId);

$Promotedcart[] = $PromoteProductArray;

setcookie("Promotedcart", serialize($Promotedcart), time()+604800,'/');

```

And when the cookie is created then i am using the unserialize php function.

```
print_r(unserialize($_COOKIE['Promotedcart'])); 

```

it does not work.

When I `print_R($_COOKIE)` then it show me the value.
