What are the best practices for converting a timestamp back into a readable date format using PHP?

When converting a timestamp back into a readable date format in PHP, the date() function can be used to format the timestamp according to the desired date format. The timestamp can be passed as the second argument to the date() function to get the corresponding date in the specified format.

$timestamp = 1634241600; // Example timestamp
$date = date('Y-m-d H:i:s', $timestamp); // Convert timestamp to readable date format
echo $date; // Output: 2021-10-14 00:00:00
