如何使用foreach从这个具有std对象的数组中获取值？

Array (
    [0] => stdClass Object (
        [SubmissionValueId] => 28
        [FormId] => 3
        [SubmissionId] => 4
        [FieldName] => Typ
        [FieldValue] => Panoramiczny
        ) 
    [1] => stdClass Object (
        [SubmissionValueId] => 29
        [FormId] => 3
        [SubmissionId] => 4
        [FieldName] => Producent
        [FieldValue] => sony
        )
    [2] => stdClass Object (
        [SubmissionValueId] => 30
        [FormId] => 3
        [SubmissionId] => 4
        [FieldName] => Model
        [FieldValue] => sony
        )
    [3] => stdClass Object (
        [SubmissionValueId] => 31
        [FormId] => 3
        [SubmissionId] => 4
        [FieldName] => Rok produkcji
        [FieldValue] => 1993
        )
    [4] => stdClass Object (
        [SubmissionValueId] => 32
        [FormId] => 3
        [SubmissionId] => 4
        [FieldName] => Nr seryjny
        [FieldValue] => sdadas
        )
    [5] => stdClass Object (
        [SubmissionValueId] => 33
        [FormId] => 3
        [SubmissionId] => 4
        [FieldName] => Nr seryjny lampy
        [FieldValue] => sdadsd
        )
    [6] => stdClass Object (
        [SubmissionValueId] => 34
        [FormId] => 3
        [SubmissionId] => 4
        [FieldName] => data2
        [FieldValue] => 05.08.2012
        )
    [7] => stdClass Object (
        [SubmissionValueId] => 35
        [FormId] => 3
        [SubmissionId] => 4
        [FieldName] => Wyslij
        [FieldValue] => Wyślij
        ) 
    [8] => stdClass Object (
        [SubmissionValueId] => 36
        [FormId] => 3
        [SubmissionId] => 4
        [FieldName] => formId
        [FieldValue] => 3 
        ) 
    )

F.ex我需要['FieldName']我试过

 foreach ($wartosci as $value)
    { echo $value['FieldName'];}

但它没有用。

Answer 1

我知道了，感谢Grzegorz，这里有解决方案：

foreach ($wartosci as $value)
        {
        echo $value->FieldName;
        }

Answer 2

因为它不是一个数组对象，而是std对象，你不能用$array['key']

来调用它

表示数组变量。

foreach ($wartosci as $value)
    { echo $value['FieldName']; }

用于标准对象。

foreach ($wartosci as $value)
    { echo $value->FieldName; }

在请求开发人员帮助您之前，您应该首先在互联网上搜索。
