What are the advantages and disadvantages of storing checkbox selections as comma-separated values in a session variable in PHP?

Storing checkbox selections as comma-separated values in a session variable can be a convenient way to keep track of multiple selections. However, it can lead to issues when trying to manipulate or retrieve individual selections. A better approach would be to store the selections as an array in the session variable, which allows for easier manipulation and retrieval of individual values. 

// Storing checkbox selections as an array in a session variable
session_start();

// Checkboxes are submitted as an array
$selectedCheckboxes = $_POST['checkbox'];

// Store the selections in a session variable
$_SESSION['selectedCheckboxes'] = $selectedCheckboxes;
