What are the potential challenges of sorting and displaying data stored as timestamps in PHP?

When sorting and displaying data stored as timestamps in PHP, one potential challenge is that timestamps are typically stored as integers, making it difficult to sort them in a human-readable format. One solution is to convert the timestamps to a more readable date format before sorting and displaying them. 

// Sample array of timestamps
$timestamps = [1632350400, 1632436800, 1632523200];

// Convert timestamps to date format
$dates = array_map(function($timestamp) {
    return date('Y-m-d H:i:s', $timestamp);
}, $timestamps);

// Sort the dates
asort($dates);

// Display sorted dates
foreach ($dates as $date) {
    echo $date . "<br>";
}
