How can leap years and varying month lengths be accounted for in time calculations in PHP?

To account for leap years and varying month lengths in time calculations in PHP, you can use built-in functions like `date()` and `strtotime()`. By utilizing these functions, you can accurately calculate dates and times while considering leap years and different month lengths. 

// Calculate a future date by adding a certain number of days
$days_to_add = 365; // number of days to add
$current_date = date('Y-m-d'); // get the current date
$future_date = date('Y-m-d', strtotime($current_date . " + $days_to_add days")); // calculate the future date

echo "Future date: $future_date";
