How can mktime be optimized or simplified for calculating timestamps based on week numbers and years?

To optimize mktime for calculating timestamps based on week numbers and years, we can use the `strtotime` function along with the `date` function to achieve the desired result. By converting the week number and year into a date format recognized by `strtotime`, we can easily calculate the timestamp. 

function getTimestampFromWeekYear($week, $year) {
    $dateString = $year . 'W' . $week; // Convert week and year into a date string format
    $timestamp = strtotime($dateString); // Get timestamp from date string
    return $timestamp;
}

// Example usage
$week = 1;
$year = 2022;
$timestamp = getTimestampFromWeekYear($week, $year);
echo date('Y-m-d H:i:s', $timestamp); // Output: 2022-01-03 00:00:00
