我有一个这样的对象:

stdClass Object
(
    [_count] => 10
    [_start] => 0
    [_total] => 37
    [values] => Array
        (
            [0] => stdClass Object
                (
                    [_key] => 50180
                    [group] => stdClass Object
                        (
                            [id] => 50180
                            [name] => CriticalChain
                        )

                )

            [1] => stdClass Object
                (
                    [_key] => 2357895
                    [group] => stdClass Object
                        (
                            [id] => 2357895
                            [name] => Data Modeling
                        )

                )

            [2] => stdClass Object
                (
                    [_key] => 1992105
                    [group] => stdClass Object

                            [name] => SQL Server Users in Israel
                        )

                )

            [3] => stdClass Object
                (
                    [_key] => 37988
                    [group] => stdClass Object

                )

            [6] => stdClass Object
                (
                    [_key] => 51464
                    [group] => stdClass Object
                        (
                            [id] => 51464
                            [name] => Israel DBA's
                        )

                )

            [7] => stdClass Object

                    [group] => stdClass Object
                        (
                            [id] => 66097
                            [name] => SQLDBA
                        )

                )

            [8] => stdClass Object
                (
                    [_key] => 4462353
                    [group] => stdClass Object
                        (
                            [id] => 4462353
                            [name] => Israel High-Tech Group
                        )

                )

            [9] => stdClass Object
                (
                    [_key] => 4203807
                    [group] => stdClass Object
                        (
                            [id] => 4203807
                            [name] => Microsoft Team Foundation Server
                        )

                )

        )

)

我需要在 HTML 表中获取 ID 和名称，但我似乎很难遍历此对象。 TIA。我知道我需要访问值数组，然后访问组对象，但我在对象和数组之间的转换以及 foreach 与基于索引的迭代之间绊倒了。

例如我试过这个:

foreach ($res as $values) { print "\n"; print_r ($values); } 

它遍历对象，但它也让我没用

echo "<table>"

foreach ($object->values as $arr) {
    foreach ($arr as $obj) {
        $id   = $obj->group->id;
        $name = $obj->group->name;

        $html  = "<tr>";
        $html .=    "<td>Name : $name</td>";
        $html .=    "<td>Id   : $id</td>";
        $html .= "</tr>";
    }
}

echo "</table>";
