【问题描述】：

我在我的 laravel 项目中使用碳。我尝试更改以下日期格式。我找不到任何错误，但它显示找不到分隔符号。我就是这样做的

$employees = $request->get('employeeIds');
    $inTimes = $request->get('inTime');
    $outTimes = $request->get('outTime');

    $attendance_date = Carbon::createFromFormat('d/m/Y', $request->get('attendance_date'))->format('Y-m-d');

    //fetch employee working hours
    $workTimes = Employee::where('status', AppHelper::ACTIVE)->get()->reduce(function ($workTimes, $employee) use ($request) {
        $workTimes[$employee->id] = [
            'in_time' => null,
            'out_time' => null
        ];
        if ($employee->duty_start) {
            $workTimes[$employee->id]['in_time'] = Carbon::createFromFormat('d/m/Y H:i:s', $request->get('attendance_date') . ' ' . $employee->getOriginal('duty_start'));
        }

        if ($employee->duty_end) {
            $workTimes[$employee->id]['out_time'] = Carbon::createFromFormat('d/m/Y H:i:s', $request->get('attendance_date') . ' ' . $employee->getOriginal('duty_end'));
        }

        return $workTimes;
    });

【问题讨论】：

当心，您验证的解决方案适用于 m/d/Y，而不适用于 d/m/Y，请准确：哪一行抛出错误并提供我们无法猜测的静态数据样本$request的内容

【解决方案1】：

您可以使用 strtotime 函数解决此问题：

$attendance_date = Carbon::createFromTimestamp(strtotime($request->get('attendance_date')) )->format('Y-m-d');

//fetch employee working hours
$workTimes = Employee::where('status', AppHelper::ACTIVE)->get()->reduce(function ($workTimes, $employee) use ($request) {
    $workTimes[$employee->id] = [
        'in_time' => null,
        'out_time' => null
    ];
    if ($employee->duty_start) {
        $workTimes[$employee->id]['in_time'] = Carbon::createFromTimestamp(strtotime($request->get('attendance_date') . ' ' . $employee->getOriginal('duty_start')) );
    }

    if ($employee->duty_end) {
        $workTimes[$employee->id]['out_time'] = Carbon::createFromTimestamp(strtotime($request->get('attendance_date') . ' ' . $employee->getOriginal('duty_end')) );
    }

    return $workTimes;
});

【讨论】：

Carbon::createFromTimestamp(strtotime()) 等价于Carbon::parse()
但这不适用于您的格式 d/m/Y，因为 Carbon::createFromTimestamp(strtotime('02/03/2020')) 给您的是 2 月 3 日，而不是 3 月 2 日。
