What are some best practices for handling user input validation and database operations in PHP forms with time restrictions?

Issue: When handling user input validation and database operations in PHP forms with time restrictions, it is important to ensure that the input data is properly validated before performing any database operations. Additionally, it is crucial to handle any time restrictions accurately to prevent unauthorized access or data manipulation. 

// Validate user input
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST['username'];
    $password = $_POST['password'];
    
    // Perform validation on input data
    if (empty($username) || empty($password)) {
        echo "Username and password are required.";
    } else {
        // Check time restrictions
        $current_time = time();
        $start_time = strtotime('08:00:00');
        $end_time = strtotime('17:00:00');
        
        if ($current_time < $start_time || $current_time > $end_time) {
            echo "Access restricted outside of working hours.";
        } else {
            // Perform database operations
            // Insert data into database or perform other operations
        }
    }
}
