Are there any best practices for handling calculations involving weekdays in PHP?

When handling calculations involving weekdays in PHP, a common best practice is to use the DateTime class to manipulate dates and calculate the difference between two dates while taking into account weekdays. This can be achieved by using the `diff` method to calculate the interval between two DateTime objects and then accessing the `days` property to get the total number of weekdays. 

// Create two DateTime objects for the start and end dates
$start = new DateTime('2022-01-01');
$end = new DateTime('2022-01-31');

// Calculate the interval between the two dates
$interval = $start->diff($end);

// Get the total number of weekdays in the interval
$weekdays = 0;
for ($i = 0; $i <= $interval->days; $i++) {
    $currentDate = $start->modify("+1 day");
    if ($currentDate->format('N') < 6) {
        $weekdays++;
    }
}

echo "Total weekdays between " . $start->format('Y-m-d') . " and " . $end->format('Y-m-d') . ": " . $weekdays;
