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'] 我试过了

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

但它不起作用。

我明白了，感谢 Grzegorz，这是解决方案：

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

因为它不是数组对象，而是 std 对象，所以你不能用它来调用它$array['key']

对于数组变量。

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

对于标准对象。

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

在请开发人员帮助您之前，您应该先在 Internet 上进行搜索。
