Question

我正在制作一个简单的网站。当我创建对另一个类的引用时，我的站点退出。

$get_car_list = new GetCarList();
$car_list = $get_car_list->getEntireInventory();

在调试器点击$get_car_list = new GetCarList();时立即退出。

我引用的类的代码如下。

class GetCarList {

    public function getEntireInventory() {

        $car_list = array();

        // Connecting, selecting database
        $connection = mysqli_connect('localhost:8889', 'root', 'root')
        or die('Could not connect: ' . mysqli_connect_error());


        $queryStatementForIdList = "SELECT id FROM cars";

        $r = mysqli_query($connection, $queryStatementForIdList);

        $idList = mysqli_fetch_array($r);

        for($i = 1; $i < sizeof($idList); $i++) {
            $queryStatementForSingleCar = "SELECT * FROM cars WHERE id = " . $idList[$i];
            $b = mysqli_query($connection, $queryStatementForSingleCar);
            $carInfo = mysqli_fetch_assoc($b);
            $thisCar = new Car($carInfo['id'], $carInfo['make'], $carInfo['model'], $carInfo['year'], $carInfo['thumbnail'],
                $carInfo['photos'], $carInfo['miles'], $carInfo['price']);
            array_push($car_list, $thisCar);
        }

        return $car_list;

    }

}

我是php的新手，所以它可能非常简单。但我发现它有点奇怪，因为调试器和执行完全退出了某行代码。

编辑：这是事件的日志打印输出

Answer 1

我在做

include '../model/file.php';

当我应该做的时候

include 'model/file.php';

出于某种原因，我的IDE（PhpStorm）告诉我该文件不存在。由于一些奇怪的原因，它仍在警告。

首先打开所有错误：

error_reporting(E_ALL);
ini_set('display_errors', 1); // check your php.ini
$get_car_list = new GetCarList();
$car_list = $get_car_list->getEntireInventory();

在致电include之前，您在某处有new GetCarList();吗？或者你在这行之前有课堂申报吗？
尝试一步一步走。因此，第一次迭代是使用以下代码创建一个文件：

error_reporting(E_ALL);

ini_set('display_errors', 1); // check your php.ini

class GetCarList {
  public function getEntireInventory() {
      return 'GetCarList Response';
  }
}

$get_car_list = new GetCarList();
$car_list = $get_car_list->getEntireInventory();
echo $car_list;

所以，如果它有效，你可以用你的方法getEntireInventory()开始操作，这是不好的，所以尝试（但记住你试图在这里创建Car - 我不知道你在哪里声明该类？）：

public function getEntireInventory() {
        $car_list = array();

        $connection = mysqli_connect('localhost:8889', 'root', 'root')
        or die('Could not connect: ' . mysqli_connect_error());

       $query = "SELECT * FROM cars ";
       $result = mysqli_query($connection, $query);
       while ($carInfo = mysqli_fetch_assoc($result)) {
            $thisCar = new Car($carInfo['id'], $carInfo['make'], $carInfo['model'], $carInfo['year'], $carInfo['thumbnail'],
                $carInfo['photos'], $carInfo['miles'], $carInfo['price']);
            array_push($car_list, $thisCar);
        }
        return $car_list;
}

php执行退出特定行
