Hi everyone,

I'm attempting to store a multidimensional array into a cookie so I can pass the values and change them later.

Code:

$var1[$row]= array(
                            "id" => $arr_clave,
                            "question" => $arr_question,
                            "answerA" => $arr_answerA,
                            "answerB" => $arr_answerB,
                            "answerC" => $arr_answerC,
                            "answerD" => $arr_answerD,
                            "correct" => $arr_correct
);

Next step is serializing the array for cookie storage (if you have another method it would be nice if you post it):

Code:

$var2 = serialize($var1);
setcookie("staff", $var2);

However it doesn't create the cookie unless I use the stripslashes function:

Code:

$var2 = serialize(stripslashes($var1));
setcookie("staff", $var2);

The cookie is now created, but I have no idea whether it really stored anything or how to use it on my next page. I was hoping to use something like this:

Code:

$var = (unserialize($_COOKIE["staff"]));

Why not use session variables? Not only is it easier, but cookies can be edited and possibly changed, making it possible for people to cheat (I am assuming you are making a quiz script).

Code:

<?php
session_start();

// makes an array
$colors=array('red', 'yellow', 'blue');
// adds it to our session
$_SESSION['color']=$colors;
$_SESSION['size']='small';
$_SESSION['shape']='round';
print_r($_SESSION);
?>

Yes it's a quiz script.

Well, it is supposed to recover itself in case the browser crashes or anything happens to the server so I thought on using cookies, so when the user gets back he can continue just where he left. I'm not really sure if sessions are persistent.
