What are the best practices for sorting and displaying date data in PHP?

When sorting and displaying date data in PHP, it is best practice to use the DateTime class to ensure consistent formatting and accurate sorting. You can sort date data by converting them to DateTime objects and then using the usort function to compare and sort the dates. Finally, when displaying the sorted dates, format them using the desired date format to ensure readability. 

// Sample array of dates
$dates = ['2022-01-15', '2021-12-25', '2022-02-10'];

// Convert dates to DateTime objects
$dateObjects = array_map(function($date) {
    return new DateTime($date);
}, $dates);

// Sort the dates
usort($dateObjects, function($a, $b) {
    return $a <=> $b;
});

// Display sorted dates
foreach ($dateObjects as $date) {
    echo $date->format('Y-m-d') . PHP_EOL;
}
