What is the purpose of sorting an array by date and including the results in PHP?

When sorting an array by date in PHP, the purpose is to organize the dates in ascending or descending order for easier data manipulation and presentation. This can be useful when working with date-related data such as events, appointments, or transactions. By sorting the dates, you can easily identify the earliest or latest dates, find date ranges, or display the data in a chronological order.

// Sample array of dates
$dates = ['2022-03-15', '2022-01-20', '2022-02-10', '2022-04-05'];

// Sort the dates in ascending order
asort($dates);

// Display the sorted dates
foreach ($dates as $date) {
    echo $date . "\n";
}
