我有和对象文件，我无法获取设备列表，如何获得设备 ??如何拨打“佳能相机”这样的2个病房？

  [Camera] => stdClass Object
    (
        [Canon Camera] => stdClass Object
            (
                [DEVICES] => Array
                    (
                        [0] => Canon EOS 30
                        [1] => Canon EOS 5D Mark II
                        [2] => Canon EOS 7D
                        [3] => Canon EOS A2
                        [4] => Canon EOS Digital Rebel (300D)
                        [5] => Canon EOS Rebel XS
                        [6] => Canon PowerShot 1200
                        [7] => Canon PowerShot A200
                        [8] => Canon PowerShot A520
                        [9] => Canon PowerShot A550


                    )

            )

Answer 1

尝试：

$object->Camera->{'Canon Camera'}->DEVICES

然后您将可以访问DEVICES数组。

foreach ( $object->Camera->{'Canon Camera'}->DEVICES as $device ) {
  echo $device . <br/>;
}

Answer 2

删除数组中的空格，将Canon Camera设为canon_camera

之后，你可以打开它：

$camera->canon_camera->DEVICES

Answer 3

您可以使用

$object->Camera->{'Canon Camera'}->DEVICES

Answer 4

所以你试图做这样的事情？：

foreach($devices_list->Camera->{'Canon Camera'}->DEVICES as $key => $value) {
  echo $value."\n";
}
