What are the potential security risks of using a button-based access control system in PHP?

One potential security risk of using a button-based access control system in PHP is that users may be able to manipulate the buttons or form data to gain unauthorized access to certain parts of the application. To mitigate this risk, it is important to validate user input and implement proper authorization checks before granting access to sensitive areas of the application. 

// Validate user input and implement proper authorization checks
if(isset($_POST['submit_button'])) {
    $access_level = $_POST['access_level'];

    // Check if user has the necessary access level
    if($access_level == 'admin') {
        // Grant access to admin section
    } else {
        // Redirect or display an error message
    }
}
