php - PHP:将秒转换为分钟和小时

我想把一定的秒数转换成分钟甚至小时。但我不想每分钟每小时都写一个if从句…
我怎么能用最简单的方法做到这一点，用最简单的方法就是最短的。；
PHP:

$countholen = mysqli_fetch_array(mysqli_query($db, "
SELECT * FROM `blablabla` WHERE `blabla` = 'bla'
"));
$countholenfetch = $countholen["count"];
if ($countholenfetch <= 60){
    $count = $countholenfetch . " sec";
}
if ($countholenfetch > 60){
    $countholenfetch = $countholenfetch - 60;
    $count = "1 min" . " + " . $countholenfetch . " sec";
}
//...if clause with 120, 180, 240 etc. instead of 60 till 3600 and another if clause in an if clause...
echo $count;

最佳答案

看看gmdate()函数。

$countholen = mysqli_fetch_array(mysqli_query($db, "
SELECT * FROM `blablabla` WHERE `blabla` = 'bla'
"));
$countholenfetch = $countholen["count"];

echo gmdate("H:i:s", $countholenfetch);

注意：如果你用的是大数字，那么就用这样的方法来代替，

$seconds = 86401 ;
$hours = floor($seconds / 3600);
$seconds -= $hours * 3600;
$minutes = floor($seconds / 60);
$seconds -= $minutes * 60;

echo "$hours:$minutes:$seconds"; //24:0:1
