How can the use of DateTime or format() from DateTime in PHP improve the readability and longevity of timestamp-based filenames?

Using DateTime or format() from DateTime in PHP can improve the readability and longevity of timestamp-based filenames by allowing you to easily format the timestamp in a human-readable way. This makes it easier for developers to understand when the file was created or modified without having to decipher a long string of numbers. Additionally, using DateTime allows for more flexibility in how the timestamp is displayed, making it easier to adapt to changing requirements in the future. 

$timestamp = time();
$date = new DateTime();
$date->setTimestamp($timestamp);
$formatted_timestamp = $date->format('Y-m-d_H-i-s');
$filename = "file_" . $formatted_timestamp . ".txt";
echo $filename;
