How can PHP and MySQL be effectively combined to calculate and display weekdays between two dates in a database, especially when the date range is less than 7 days?

When calculating and displaying weekdays between two dates in a database using PHP and MySQL, one approach is to use a loop to iterate through each day between the start and end dates, check if it's a weekday (Monday to Friday), and then display or store the weekdays accordingly. To achieve this, you can utilize PHP's date and strtotime functions along with MySQL queries to fetch the relevant data. 

// Assuming $start_date and $end_date are the start and end dates in 'Y-m-d' format
$start_date = '2022-01-01';
$end_date = '2022-01-07';

$current_date = $start_date;
while (strtotime($current_date) <= strtotime($end_date)) {
    $day_of_week = date('N', strtotime($current_date)); // Get the day of the week (1 = Monday, 7 = Sunday)
    
    if ($day_of_week >= 1 && $day_of_week <= 5) {
        // Display or store the weekday in the database
        echo $current_date . " is a weekday.\n";
    }
    
    $current_date = date('Y-m-d', strtotime($current_date . ' +1 day'));
}
