What are some common methods for calculating the end date of a specific period in PHP, such as a 3-month period?

When calculating the end date of a specific period in PHP, such as a 3-month period, you can use the `strtotime` function along with the `date` function. By adding the desired number of months to the start date, you can easily determine the end date of the period. 

// Calculate the end date of a 3-month period from a given start date
$start_date = '2022-01-01';
$end_date = date('Y-m-d', strtotime($start_date . ' +3 months'));

echo "Start Date: " . $start_date . "\n";
echo "End Date: " . $end_date;
