在PHP 中减去日期

我有两个Unix时间戳，如何计算它们之间的总天数？

Answer 1

$timestamp1 = x;
$timestamp2 = y;
$days_elapsed = floor(($timestamp2 - $timestamp1)/86400);
echo $days_elapsed;

Answer 2

将它们转换为UNIX时间戳(如果它们还没有(，然后只转换

$diff = abs($timestamp1 - $timestamp2);
$days = (int) ($diff / 60 / 60 / 24); 

Answer 3

应该这样做：
$days = (strtotime($timestamp1)-strtotime($timestamp2))/(60*60*24);

Answer 4

这个代码应该能完成

$numDays = abs($timeOne - $timeTwo)/60/60/24;
