What is the significance of the "return" command in a PHP function for access control?

The "return" command in a PHP function is significant for access control as it allows the function to return a value or exit early based on certain conditions. By using the "return" command, you can control the flow of the function and restrict access to certain parts of the code based on specific criteria. 

function checkAccess($userRole) {
    if ($userRole !== 'admin') {
        return false; // Deny access if user is not an admin
    }

    // Code for admin-only functionality goes here

    return true; // Allow access for admin users
}
