What are some potential pitfalls to be aware of when using PHP to determine if a given date is a workday or not?

One potential pitfall when using PHP to determine if a given date is a workday is not accounting for holidays or weekends. To address this, you can create an array of holidays and weekends, and check if the given date falls on any of those days before determining if it is a workday. 

function isWorkday($date) {
    $weekendDays = [0, 6]; // 0 represents Sunday, 6 represents Saturday
    $holidays = ['2022-01-01', '2022-07-04']; // Add more holidays as needed
    
    $dayOfWeek = date('w', strtotime($date));
    $formattedDate = date('Y-m-d', strtotime($date));
    
    if (in_array($dayOfWeek, $weekendDays) || in_array($formattedDate, $holidays)) {
        return false;
    }
    
    return true;
}

// Example usage
$date = '2022-01-03';
if (isWorkday($date)) {
    echo $date . ' is a workday.';
} else {
    echo $date . ' is not a workday.';
}
