Answer 1

尝试，

$date = new DateTime("@$diffrence");
echo $date->format('H:i:s') . "\n";

或者

$date = new DateTime();
$date->setTimestamp( $diffrence);
echo $date->format('H:i:s');

使用date_diff()方法！

<?php
  $datetime1 = new DateTime('2009-10-11');
  $datetime2 = new DateTime('2009-10-13');
  $interval = $datetime1->diff($datetime2);
  echo $interval->format('%R%a days');
?>

date如果您不需要该对象，可以只使用 PHP 的函数。

echo date("H:i:s", $diffrence);
