How can the timestamp be effectively incremented within a loop to calculate workdays in PHP?

To calculate workdays in PHP by incrementing a timestamp within a loop, you can use a while loop to iterate through each day and check if it falls within a workday (Monday to Friday). You can increment the timestamp by one day using the strtotime function and check if the day of the week is not Saturday or Sunday using the date function. Keep a counter to track the number of workdays found. 

$start_date = strtotime('2022-01-01');
$end_date = strtotime('2022-01-31');
$workdays = 0;

while ($start_date <= $end_date) {
    if (date('N', $start_date) <= 5) {
        $workdays++;
    }
    $start_date = strtotime('+1 day', $start_date);
}

echo "Number of workdays: " . $workdays;
