Php中循环stdClass对象时出现的问题

我在使用php循环json对象时遇到了一个奇怪的问题。这是我的数据格式

stdClass Object
(
[userform] => Array
    (
        [0] => stdClass Object
            (
                [id] => 69
                [product] => testuser
            )

        [1] => stdClass Object
            (
                [id] => 70
                [product] => testuser
            )

        [2] => stdClass Object
            (
                [id] => 71
                [product] => testuser
            )

        [3] => stdClass Object
            (
                [id] => 72
                [product] => testuser
            )

        [4] => stdClass Object
            (
                [id] => 73
                [product] => testuser
            )

        [5] => stdClass Object
            (
                [id] => 74
                [product] => testuser
            )

        [6] => stdClass Object
            (
                [id] => 75
                [product] => testuser
            )

        [7] => stdClass Object
            (
                [id] => 76
                [product] => testuser
            )

        [8] => stdClass Object
            (
                [id] => 77
                [product] => testuser
            )

        [9] => stdClass Object
            (
                [id] => 78
                [product] => testuser
            )

        [10] => stdClass Object
            (
                [id] => 79
                [product] => testuser
            )

        [11] => stdClass Object
            (
                [id] => 80
                [product] => testuser
            )

        [12] => stdClass Object
            (
                [id] => 81
                [product] => testuser
            )

        [13] => stdClass Object
            (
                [id] => 82
                [product] => testuser
            )

        [14] => stdClass Object
            (
                [id] => 83
                [product] => testuser
            )

        [15] => stdClass Object
            (
                [id] => 84
                [product] => testuser
            )

        [16] => stdClass Object
            (
                [id] => 85
                [product] => testuser
            )

        [17] => stdClass Object
            (
                [id] => 86
                [product] => testuser
            )

        [18] => stdClass Object
            (
                [id] => 87
                [product] => testuser
            )

        [19] => stdClass Object
            (
                [id] => 88
                [product] => testuser
            )

        [20] => stdClass Object
            (
                [id] => 89
                [product] => testuser
            )

    )

)

但是这个循环抛出以下错误

尝试获取中非对象的属性

请告诉我如何从上述格式中读取产品属性值

感谢所有foreach应该在

$data->userform

，而不仅仅是

$data

foreach($data->userform as $key=>$row){
             if(isset($row->product)){
               print_r($key);
               print_r($row->product);  
             }else{
               //product property is not set
             }
         }

您有一个输入错误：

if（isset（$roow

@mavrosxristoforos）这是另一个错误，但是

if（isset（$roow

始终返回false他/她有其他错误要查找您的意思是

$data->userform as$key=>$row

？是的，这是打字错误，但总是执行其他条件在获得相同错误时，我用$data变量fomat编辑了问题。如果该结构与您提到的100%相同，则无法再获得该错误，使用相同的名称。是的，这不是抛出错误，但我如何从该数据格式读取产品属性值？只有设置了才能读取，如果未设置，如何读取？因此您的

print\r（$row->product）；

必须进入

if

的内部，而不是

else

的内部。请参见编辑
