如何从日期数组中获取不同的日期

Question

我有这样的代码

$awal  = date_create('$value[tgl_kembali]');

$akhir = date_create(); // waktu sekarang

$diff  = date_diff($awal, $akhir); 

echo 'Total selisih hari : ' . $diff->days;

使用这段代码，我想获得不同日期的表单变量，$awal该变量是数据数组$akhir，并且我有这样的错误：

Warning: date_diff() expects parameter 1 to be DateTimeInterface, bool given in C:\xampp\htdocs\Travel.remove\Travel\admin\pesanan.php on line 54

Notice: Trying to get property 'days' of non-object in C:\xampp\htdocs\Travel.remove\Travel\admin\pesanan.php on line 55

Answer 1

<?php$datetime1 = new DateTime('2009-10-11');$datetime2 = new DateTime('2009-10-13');$interval = $datetime1->diff($datetime2);echo $interval->format('%R%a days');?>111
