What security considerations should be taken into account when managing opening hours for a large number of clients and locations in a PHP application?

When managing opening hours for a large number of clients and locations in a PHP application, it is important to ensure that only authorized users can modify these hours to prevent unauthorized changes. One way to enhance security is to implement role-based access control, where only users with specific roles (such as administrators) have permission to update opening hours. Additionally, input validation should be enforced to prevent injection attacks and ensure that the data being stored is in the correct format. 

// Example code snippet for role-based access control in PHP
if($_SESSION['role'] !== 'admin'){
    // Redirect unauthorized users to a different page or display an error message
    header("Location: unauthorized.php");
    exit();
}

// Code to update opening hours goes here
