setcookie doesn't work on linux

Question

I recently installed centos(linux) on my pc. I have a piece of code in which setcookie function is used for displaying a message. It works perfectly on all other windows pcs connected in a network. I have no clue about what is wrong. Is there need of any additional parameter to be applied in setcookie function for linux?

The code I applied is as follows:

    setcookie("msg","This record already exist",time()+5,"/");
    header("location:".SITE."index.php?page=inventory_sub_categoryfrm);
    exit;

and isset($_COOKIE['msg']) returns false.

Http header:

Answer 1

There is a typo, you forgot a double quote:

header("location:".SITE."index.php?page=inventory_sub_categoryfrm);
//                                                       here ---^

Also the cookie lifetime is too short, you're giving it 5 seconds by using time()+5 , so please give it a longer life span time()+86400 .
