What are some alternative methods or functions in PHP that can be used for date calculations in loops?

When performing date calculations in loops in PHP, it is important to ensure that the date values are correctly incremented or decremented based on the loop iteration. One alternative method to achieve this is by using the `strtotime()` function in combination with `date()` function to manipulate the date values within the loop. 

// Example of using strtotime() and date() for date calculations in a loop
$start_date = '2022-01-01';
$end_date = '2022-01-10';

$current_date = $start_date;

while (strtotime($current_date) <= strtotime($end_date)) {
    echo $current_date . "\n";
    
    // Increment the current date by 1 day
    $current_date = date('Y-m-d', strtotime($current_date . ' +1 day'));
}
