How can PHP developers efficiently iterate through a series of dates to calculate specific deadlines or expiration dates, as discussed in the forum thread?

To efficiently iterate through a series of dates in PHP to calculate specific deadlines or expiration dates, developers can use the DateTime class along with a loop to increment or decrement the dates as needed. By setting the initial date and then modifying it within a loop, developers can easily calculate deadlines or expiration dates based on specific criteria. 

$startDate = new DateTime('2022-01-01');
$endDate = new DateTime('2022-12-31');

while ($startDate <= $endDate) {
    // Perform calculations or check deadlines here
    // For example, check if the current date is a deadline or expiration date
    
    // Increment the date by one day
    $startDate->modify('+1 day');
}
