What are some common pitfalls when sorting and displaying data in PHP, especially when dealing with timestamps?

One common pitfall when sorting and displaying data in PHP, especially when dealing with timestamps, is not properly converting timestamps to a format that can be easily sorted. To solve this issue, you can use the `strtotime()` function to convert the timestamps to Unix timestamps before sorting them. This allows for easier comparison and sorting based on the actual time values. 

// Sample array of timestamps
$timestamps = ['2022-01-15 10:30:00', '2022-01-16 09:45:00', '2022-01-14 12:15:00'];

// Convert timestamps to Unix timestamps
$unixTimestamps = array_map('strtotime', $timestamps);

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

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