Store a complete array in a cookie

I have the following array:

Array ( [0] => 1 [1] => 1 [2] => 3 [3] => 6 )

and I would like to store it in a cookie. This is the code I tried:

$cart_array = Array ( [0] => 1 
          [1] => 1 
          [2] => 3 
          [3] => 6 );

setcookie('cart_array',$cart_array,time()+3600);

when I display the contents of the cookie using print_r($_Cookie), this is what I get:

Array ( [cart] => Array ( [0] => 6 [id] => 2 ) [_ga] => GA1.1.499529088.1424453778 [PHPSESSID] => aj8p5l5ph77n04tab50i83ie34 )

instead of the array I inserted to cookie. Please assist

Use serialize()

setcookie('cart_array',serialize($cart_array),time()+3600);

$cart_array = unserialize($_COOKIE['cart_array']);

Depending on special characters that may arise (not likely, but good to know if you do) you may also need urlencode():

setcookie('cart_array',urlencode(serialize($cart_array))),time()+3600);


$cart_array = unserialize(urldecone($_COOKIE['cart_array']));

I think you're looking for serialize:

<?php
$a = array(1 => 'a', 2 => 'b', 3 => 'c');
$b = serialize($a);
var_dump($b); ////Returns this string(42) "a:3:{i:1;s:1:"a";i:2;s:1:"b";i:3;s:1:"c";}"
$c = unserialize($b);
print_r($c); //Return the same thing as $a

Try out this code, you use serialize to convert an array to string and then you can easily store it. Then, you unserialize to have the array back !

Use this:

setcookie('cart_array',implode('|',$cart_array),time()+3600);

Use this to read cookie back to array:

$cart_array = explode('|',$_COOKIE['cart_array'])

Although I don't think its really necessary to do that. but, just answering your question.

And please be careful to the total length of the Cookie What is the maximum size of a cookie

Cookies does not work with arrays - they are only strings on the local computer. With

$res = serialize($arr);

you can convert an array to a string. (Convert it back with unserialize($arr).)
