What alternative method can be used to convert a date in an outdated German format to a number in PHP?

To convert a date in an outdated German format (dd.mm.yyyy) to a number in PHP, you can use the `strtotime()` function along with `date()` function. First, you need to use `str_replace()` to replace the dots with dashes in the date string. Then, you can pass this modified date string to `strtotime()` to convert it to a Unix timestamp, which can be further formatted using the `date()` function to get the desired number representation. 

$date = '25.12.2021';
$modified_date = str_replace('.', '-', $date);
$timestamp = strtotime($modified_date);
$number_representation = date('Ymd', $timestamp);

echo $number_representation; // Output: 20211225
