What best practices should be followed when creating an admin interface for PHP scripts?

When creating an admin interface for PHP scripts, it is important to follow best practices to ensure security and functionality. This includes implementing user authentication, input validation, and proper error handling. Additionally, using a template system for the interface design can help maintain consistency and ease of maintenance. 

// Example code snippet for implementing user authentication in PHP admin interface

session_start();

// Check if user is logged in
if(!isset($_SESSION['admin_user'])) {
    header("Location: login.php");
    exit();
}

// Validate user input
if($_SERVER['REQUEST_METHOD'] == 'POST') {
    // Perform input validation here
}

// Error handling
try {
    // Code logic here
} catch(Exception $e) {
    echo "An error occurred: " . $e->getMessage();
}
