In PHP, what steps should be taken to avoid code duplication and data overwriting issues when sorting date and time data for display?

When sorting date and time data for display in PHP, it is important to avoid code duplication and data overwriting issues by using a consistent format for date and time manipulation. One way to achieve this is by storing date and time values in a standardized format, such as Unix timestamp, and then converting them to the desired display format when needed. By centralizing date and time manipulation logic in functions or classes, you can reduce code duplication and ensure data integrity. 

// Sample code snippet to demonstrate sorting date and time data in PHP

// Define an array of date and time values
$dates = [
    '2022-01-15 10:30:00',
    '2022-01-10 15:45:00',
    '2022-01-20 08:00:00'
];

// Convert date and time values to Unix timestamp for sorting
$timestamps = [];
foreach ($dates as $date) {
    $timestamps[] = strtotime($date);
}

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

// Display the sorted date and time values
foreach ($timestamps as $timestamp) {
    echo date('Y-m-d H:i:s', $timestamp) . "\n";
}
