----------------------
25.06.08  : 2008-06-25
25.06.2008: 2008-06-25

echo "PHP VERSION: ".PHP_VERSION."\n";
for($i = 1; $i <= 30; ++$i) {
    $day = str_pad($i, 2, '0', STR_PAD_LEFT);
    $dateTwo = "$day.06.08";
    $dateFour = "$day.06.2008";
    echo $dateTwo."  : ".date("Y-m-d", strtotime($dateTwo));

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

"24.06.08" is interpreted as 24h 06m 08s, and because there is no hour 25, that specific rule fails and it falls back to 25d 06m 2008y.

Run:

var_dump(date_parse('24.06.08'));

to see it for yourself.
