What are the best approaches for displaying timestamps accurately in PHP, considering different timestamp lengths?

When displaying timestamps in PHP, it is important to consider the different lengths of timestamps that may be used. To accurately display timestamps, you can use the date() function along with the strtotime() function to convert timestamps into a human-readable format. Additionally, you can use the DateTime class for more advanced timestamp formatting. 

// Example of displaying timestamps accurately in PHP
$timestamp = 1633520400; // Example timestamp

// Using date() function with strtotime() to display timestamp
echo date('Y-m-d H:i:s', strtotime($timestamp));

// Using DateTime class for more advanced formatting
$date = new DateTime();
$date->setTimestamp($timestamp);
echo $date->format('Y-m-d H:i:s');
