PHP Soap请求foreach

我有一个Souap请求，我不知道如何使用foreach查看所有VoucherCodeItems。 我试过这个，但不起作用：

foreach($response->VoucherCodeCollection->VoucherCodeItem AS $key => $val) {
 echo "Feld $key hat den Wert: $val<br>";
}

结果

stdClass Object
(
    [TotalResults] => 2
    [VoucherCodeCollection] => stdClass Object
        (
            [VoucherCodeItem] => Array
                (
                    [0] => stdClass Object
                        (
                            [Id] => 215523
                            [ProgramId] => 6767
                            [Code] => 
                            [Title] => Adventskalender
                            [Description] => Im Adventskalender
                        )
                    [1] => stdClass Object
                        (
                            [Id] => 215453
                            [ProgramId] => 8476
                            [Code] => 
                            [Title] => Wir schenken dir 15 EUR!!
                            [Description] => 
                        )


                )

        )

)

无法直接回显对象：

$val只是对象的一部分，请使用->符号访问其属性。谢谢，这很有帮助：

stdClass Object
(
    [TotalResults] => 2
    [VoucherCodeCollection] => stdClass Object
        (
            [VoucherCodeItem] => Array
                (
                    [0] => stdClass Object
                        (
                            [Id] => 215523
                            [ProgramId] => 6767
                            [Code] => 
                            [Title] => Adventskalender
                            [Description] => Im Adventskalender
                        )
                    [1] => stdClass Object
                        (
                            [Id] => 215453
                            [ProgramId] => 8476
                            [Code] => 
                            [Title] => Wir schenken dir 15 EUR!!
                            [Description] => 
                        )


                )

        )

)

foreach ($response->VoucherCodeCollection->VoucherCodeItem as $key => $val) {
 echo "Feld $key hat den Wert: {$val->Title}<br>";
}
