PHP 배열을 쿠키에 어떻게 저장하며 보안 및 직렬화에 대한 모범 사례는 무엇입니까?

<code class="php">setcookie('your_cookie_name', json_encode($info), time()+3600);</code>

<code class="php">$encodedArray = implode(',', $info);
setcookie('your_cookie_name', $encodedArray, time()+3600);</code>

<code class="php">setcookie('my_array[0]', 'value1' , time()+3600);
setcookie('my_array[1]', 'value2' , time()+3600);
setcookie('my_array[2]', 'value3' , time()+3600);</code>

<code class="php">echo '<pre class="brush:php;toolbar:false">';
print_r( $_COOKIE );
die();</code>

<code class="html"><b>Array
(   
    [my_array] => Array
        (
            [0] => value1
            [1] => value2
            [2] => value3
        )

)</b></code>
