Hallo,

hab im Netz eine Lösung gefunden, dass man für eine kleine Berechnung ca. 40 Zeilen Code schreiben ist echt der Wahnsinn :/

function makeDifferenz($first, $second)
{
	
	if($first > $second)
		$td['dif'][0] = $first - $second;
	else
		$td['dif'][0] = $second - $first;
	
	$td['sec'][0] = $td['dif'][0] % 60; // 67 = 7

	$td['min'][0] = (($td['dif'][0] - $td['sec'][0]) / 60) % 60;
	
	$td['std'][0] = (((($td['dif'][0] - $td['sec'][0]) /60)- $td['min'][0]) / 60) % 24;
	
	$td['day'][0] = floor( ((((($td['dif'][0] - $td['sec'][0]) /60)- $td['min'][0]) / 60) / 24) );
	
	$td = makeString($td);
	
	return $td;
	
}

function makeString($td)
{
	
	if ($td['min'][0] == 1)
		$td['min'][1] = 'Minute';
	else
		$td['min'][1] = 'Minuten';
		
	if ($td['std'][0] == 1)
		$td['std'][1] = 'Stunde';
	else
		$td['std'][1] = 'Stunden';
		
	if ($td['day'][0] == 1)
		$td['day'][1] = 'Tag';
	else
		$td['day'][1] = 'Tage';
	
	return $td;
	
}

$secLast = time();
$secNow = mktime ( 10, 53, 0, 3, 6, 2015 );

$td = makeDifferenz($secLast, $secNow);

if ($td['day'][0] < 1) {
echo $td['std'][0] . ' ' . $td['std'][1] . ', ' . $td['min'][0] . ' ' . $td['min'][1]; 	
}
else {
echo $td['day'][0] . ' ' . $td['day'][1] . ', ' . $td['std'][0] . ' ' . $td['std'][1] . ', ' . $td['min'][0] . ' ' . $td['min'][1];
	}
?>

Ich dachte eher dass MySQL so etwas direkt kann. Es funktioniert und alles andere soll mir erstmal egal sein.
