Question

最近我试图为我的软件工程课程项目做一个模型视图控制器。我的设备模型函数都工作正常，除了函数listallmydevices（）idk whats正在进行并且没有错误可见。

注意我已将我的功能从另一个类更改为另一个列表功能，并且除了设备

之外它的工作正常

public static function listalldevices()

 {
     $devobj=new device($row["DeviceID"]);

     $result[$i]=$devobj;

     $i++;
 }
 return $result;


}

设备控制器

if(isset($_POST['VIEWALLDEVICES']))
 {

    $array= Device::listalldevices();

    echo "All devices";

    for($i=0; $i<count($array); $i++)
    {

        echo $array[$i]->DeviceID;
        echo $array[$i]->Name;
        echo $array[$i]->Date;
        echo $array[$i]->Amount;
        echo $array[$i]->Price;
        echo $array[$i]->Brand;
    }
