How can a PHP user convert a week/year format to a timestamp?

To convert a week/year format to a timestamp in PHP, you can use the `strtotime` function along with some date manipulation. First, you need to calculate the first day of the week based on the week and year provided. Then, you can use this information to create a date string and convert it to a timestamp using `strtotime`. 

$week = 42;
$year = 2022;

$first_day_of_week = date('Y-m-d', strtotime($year . 'W' . $week));
$timestamp = strtotime($first_day_of_week);

echo $timestamp;
