Question

我正在尝试创建一个用于验证时间变量日期和时间的控制器。问题在于代码可以正确地验证日期和签入时间，但对于签出时间始终会得到错误的值。 $checkOut的每个变量总是以Not Valid, Wrong Check Out Time Format验证。

更新：现在，我在这里仅使用2个控制器，扩展checkerController的debug_controller将接收csv文件并检查csv文件中的每一行。如果有任何无效的数据格式，$result将包含“格式无效的原因”。使用此值为validateDate($id, $date, $checkIn, $checkOut)的代码$checkOut实际上应该为false时，返回false。

奇怪的是，当我使用更少的csv文件行时，最后一行实际上可以返回true。

第一个控制器包含检查输入的功能

<?php

namespace App\Http\Controllers;

use Illuminate\Support\Facades\DB;
use Illuminate\Http\Request;
use DateTime;

class checkerController extends Controller {

    function validateTime($time)
    {
        $d = DateTime::createFromFormat('H:i:s', $time);
        return $d && $d->format('H:i:s') == $time;
    }

    function validateDate($id, $date, $checkIn, $checkOut)
    {
        $d = DateTime::createFromFormat('Y-m-d', $date);
        $valid = ($d && $d->format('Y-m-d') == $date);
        if ($valid == false) {
            $data = "Not Valid, Wrong Date Format";
            return $data;
        } else {
            $validCheckOut = $this->validateTime("$checkOut");
            if ($validCheckOut == false) {
                return "checkout not valid --> $checkOut";
            } else {
                return "checkout valid";
            }

        }
    }
}

第二个控制器，获取请求的csv文件，继承父checkerController

<?php

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\DB;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\URL;
use Illuminate\Support\Str;
use Storage;


class debug_controller extends checkerController {

    function index(request $request){
        $ext = $request->file('csv')->getClientOriginalExtension();
        $filename = Str::random(10).".$ext";
        $path=$request->file('csv')->storeAs('public/csv/', $filename);
        $dir = asset("storage/csv/$filename");
        $file = file("$dir");
        $arrContent = Array();
        foreach ($file as $key) {
            list($id,$date,$checkIn,$checkOut)=explode(",", $key);
            $result = $this->validateDate($id,$date,$checkIn,$checkOut);;           
            $arrtemp = array('id'=> $id, 'date' => $date, 'checkIn' => $checkIn, 'checkOut' => $checkOut, 'result' => $result);
            array_push($arrContent, $arrtemp);
        }
        foreach ($arrContent as $row) {
            echo $row['id']." | ".$row['date']." | ".$row['checkIn']." | ".$row['checkOut']." | ".$row['result']."<br><br>";
            }   
    }
}
?>

要获取列的每个值，我使用list($id,$date,$checkIn,$checkOut)=explode(",", $key);将每个列分配给一个变量。问题是爆炸的最后一个值没有定界符的,。因此，即使值是完全相同的字符串，由于某种原因，它也总是返回false。将逗号添加到最后一个值时，代码可以很好地验证。这是添加了逗号最后值的输入：

时间验证始终返回false。 PHP DateTime，Laravel
