What are some best practices for handling and displaying date differences in PHP, especially in the context of a foreach loop?

When handling and displaying date differences in PHP within a foreach loop, it is important to ensure that the date calculations are accurate and that the output is formatted correctly. One common approach is to use the DateTime class to calculate the date differences and then format the output using the date_diff function. This allows for easy manipulation of dates and ensures consistency in the displayed information. 

// Sample array of dates
$dates = ['2022-01-01', '2022-01-15', '2022-02-01', '2022-03-10'];

// Loop through each date and display the date difference
foreach ($dates as $date) {
    $currentDate = new DateTime();
    $eventDate = new DateTime($date);
    
    $interval = $currentDate->diff($eventDate);
    
    echo 'Event date: ' . $eventDate->format('Y-m-d') . ' | Days until event: ' . $interval->days . ' days' . PHP_EOL;
}
