echo(strtotime("now"));
echo(strtotime("3 October 2005"));

echo(strtotime("next Monday"));

1139219304
1139503709
1139180400

$str = 'Not Good';

// previous to PHP 5.1.0 you would compare with -1, instead of false
if (($timestamp = strtotime($str)) === false) {
echo "The string ($str) is bogus";
} else {
echo "$str == " . date('l dS of F Y h:i:s A', $timestamp);
}
?>

I just found out PHP thinks slashes in date-formats aren't very european:
(I guess this is not a bug, just the way it works. But correct me if I'm wrong.)

$date = "06/10/2011 14:28"; // 6 october 2011 2:28 pm
$otherDate = "06-10-2011 14:28"; // 6 october 2011 2:28 pm

echo $stamp = strtotime($date) . "
"; // outputs 1307708880
echo $otherStamp = strtotime($otherDate) . "
"; // outputs 1317904080

echo date("d-m", $stamp); // outputs 10-06
echo date("d-m", $otherStamp); // outputs 06-10

?>
