php strtotime()函数时间日期转换

echo strtotime("now"), "n";
echo strtotime("10 September 2000"), "n";
echo strtotime("+1 day"), "n";
echo strtotime("+1 week"), "n";
echo strtotime("+1 week 2 days 4 hours 2 seconds"), "n";
echo strtotime("next Thursday"), "n";
echo strtotime("last Monday"), "n";
?>

$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

?>
