How to convert a string to a timestamp and then back to a string with PHP

```php $r = date_parse("8:16:12 01.02.2008"); $d = mktime($r['hour'], $r['minute'], $r['second'], $r['month'], $r['day'], $r['year']); echo date("H:i:s d.m.Y", $d); ``` Prints out the following: ```php 8:16:12 01.02.2008 ```
