php – 如何检查此时间戳是今天,明天还是后天？

我想知道如何检查时间戳是今天,明天还是后天.

我有例如：

$timestamp = "1313000474";

如何查看此时间戳是今天,明天还是后天？

例如

if today then echo $output = "today";
if tomorrow then echo $output = "tomorrow";
if the day after tomorrow then echo $output = "dayaftertomorrow";

这该怎么做？

编辑：更正了unix时间戳

先感谢您.

$timestamp = "1313000474";

$date = date('Y-m-d',$timestamp);
$today = date('Y-m-d');
$tomorrow = date('Y-m-d',strtotime('tomorrow')); 
$day_after_tomorrow = date('Y-m-d',strtotime('tomorrow + 1 day'));

if ($date == $today) {
  echo "today";
} else if ($date == $tomorrow) {
  echo "tomorrow";
} else if ($date == $day_after_tomorrow) {
  echo "dayaftertomorrow";
}
