$timestamp = 1632574810; $date = new DateTime(); $date->setTimestamp($timestamp); $interval = $date->diff(new DateTime()); echo "The difference in days is: " . $interval->format('%a days');This code sets the timestamp of the `$date` object to `1632574810`, which represents the Unix timestamp for September 25th, 2021 at 4:06:50 PM. The `diff()` method is used to calculate the difference between this date and the current date. The resulting `DateInterval` object is then used to display the difference in days using the `format()` method. Package/Library: Core PHP Library.
