    [form] => stdClass Object
        (
            [fieldsets] => Array
                (
                    [0] => stdClass Object
                        (
                            [fieldset_name] => name_1
                            [datapoints] => Array
                                (
                                    [0] => stdClass Object
                                        (

                                        )

                                    [1] => stdClass Object
                                        (
                                            [dp_id] => 5
                                        )
                                )

                        )

                    [1] => stdClass Object
                        (
                            [fieldset_name] => name_2
                            [datapoints] => Array
                                (
                                    [0] => stdClass Object
                                        (
                                            [dp_id] => 1
                                        )

                                    [1] => stdClass Object
                                        (
                                            [dp_id] => 3
                                        )

                                )

                        )

                )

        )

)

现在我想将dp id的值分别分别放入。,array(4,5)和array(1,3)中的两个数组

foreach($object->form->fieldsets as $fieldset) {
    $dp_ids = array();
    foreach($fieldset->datapoints as $datapoint)
        $dp_ids[] = $datapoint->dp_id;
    var_dump($dp_ids);
}

试试这个。

$object->form['fieldsets'][1]->datapoints[1]
