现在，我得到的值request是2021-06-08 00:31:25.168324格式。我想把它转换成datetime格式2021-06-08。如何转换这个？

 $order['pickup_date']= DateTime::parse($request->input('pickup_date'))->isoFormat('YYYY-MM-DD');

我得到的错误是“给定的数据无效”。

由于您使用的是 Laravel。您可以使用Carbon

\Carbon\Carbon::createFromFormat('Y-m-d H:i:s.u',$request->input('pickup_date'))->format('Y-m-d');

对不起，我真的不明白。

编写干净的代码有什么问题？

为什么不能使用简单的 PHP 函数？

无论您是否在前端使用任何日历/验证输入，后端数据验证都会对您有所帮助。

这是一个简单的 PHP 解决方案，您还可以在其中检查无效数据：

$dateInput = '2021-06-08 00:31:25.168324'; //$request->input('pickup_date')
$date = date_create($dateInput);
// At this point you can test invalid data, provided by user.
if (!$date) {
  return 'Please provide a valid date';
}

$formattedDate = date_format($date, "Y-m-d");
var_dump($formattedDate); // '2021-06-08'
