How to store an array in a cookie

[richie]

Hello,

How do I store an array in a cookie?

Here's what I've done that didn't work:

page_one.php

<?
$arr = array('one','two','tri');

$s_arr = serialize($arr);

setcookie('myarr', $s_arr, time()+28800, '/');

?>

<a href="./page_two.php">myarr</a>

So I load page_one.php, and click on the link to page_two.php

Here is my page_two.php

<?
$arr = $_COOKIE['myarr'];

$u_arr = unserialize($arr);

if(is_array($u_arr)) {

foreach($u_arr as $val) {
echo $val . '<p>';
}
}
else {
echo 'not array';
}

?>

The output is "not array".

So again, how do I store an array in a cookie?

There's a note on the [man]setcookie[/man] manual page that says

Cookies names can be set as array names and will be available to your PHP scripts as arrays but separate cookies are stored on the users system. Consider explode() to set one cookie with multiple names and values. It is not recommended to use serialize() for this purpose, because it can result in security holes.

Thanks for your answer.

I just did implode() on the array and stored the string in the cookie.
