  2. //Save
  3. $arr = array(1,2,3);
  4. $arr_str = serialize($arr);
  5. setcookie("a",$arr_str);
  7. //Take out
  8. $ arr_str = $_COOKIE['a'];
  9. $arr = unserialize($arr_str);
Copy code

Method 2: Set a multi-key value cookie, please note that the key value must be given

  2. $arr = array(1,2,3);
  3. setcookie("a[0]", $arr[0]);
  4. setcookie("a[1]", $arr[1] );
  5. setcookie("a[2]", $arr[2]);
Copy code

Note: The above method is copied from elsewhere. I tried the first method and it was successful. It is also more convenient. I have not tried the second method, so please test it more.
