Question

这看起来很简单，但我无法弄清楚。我有一个json_decoded的现有对象数组。我需要迭代这些对象，为每个对象附加一个新数组，然后将整个数组重新组合在一起。我无法将新数组添加到正确的位置。

["bar", "baz" ...]

以下是我开始使用的其中一个对象的示例（当然在function appendToArray($arrayOfObjects) { $newArray = array(); foreach ($arrayOfObjects as $object) { echo "<pre>".print_r($object, true)."</pre>"; $newItems = array('item1', 'item2', 'item3'); $moreItems = array('more1', 'more2', 'more3'); $newObject = array(); $newObject["newItems"] = $newItems; $newObject["moreItems"] = $moreItems; $rebuiltObject = array(); array_push($rebuiltObject, $object); $rebuiltObject['new_stuff'] = $newObject; // $rebuiltObject[0]['new_stuff'] = $newObject; array_push($newArray, $newObject); } return $newArray; }之后：

json_decode

完成后，我想要的是：

0 => stdClass Object
(
    [code] => some code
    [first_name] => First
    [last_name] => Last
    [urls] => stdClass Object
        (
            [news] => http://www.somesite.com/news
            [info] => http://www.somesite.com/info
        )

    [geo] => stdClass Object
        (
            [latitude] => 0.0
            [longitude] => 0.0
            [name] => building name
        )
)

但我得到的是：

0 => stdClass Object
(
    [code] => some code
    [first_name] => First
    [last_name] => Last
    [urls] => stdClass Object
        (
            [news] => http://www.somesite.com/news
            [info] => http://www.somesite.com/info
        )

    [geo] => stdClass Object
        (
            [latitude] => 0.0
            [longitude] => 0.0
            [name] => building name
        )
     [new_stuff] => Array
            (
                [newItems] => Array
                    (
                        [0] => item1
                        [1] => item2
                        [2] => item3
                    )

                [moreItems] => Array
                    (
                        [0] => more1
                        [1] => more2
                        [2] => more3
                    )

            )
)

注意[0] => stdClass Object ( [code] => some code [first_name] => First [last_name] => Last [urls] => stdClass Object ( [news] => http://www.somesite.com/news [info] => http://www.somesite.com/info ) [geo] => stdClass Object ( [latitude] => 0.0 [longitude] => 0.0 [name] => building name ) ), [new_stuff] => Array ( [newItems] => Array ( [0] => item1 [1] => item2 [2] => item3 ) [moreItems] => Array ( [0] => more1 [1] => more2 [2] => more3 ) ) )如何在原始对象之外。我需要进去。我尝试过的其他一切都崩溃了，而且我完全没有想法。谁能看到我怎么做到这一点？谢谢！

您的解决方案是一个字符串：

$object->new_stuff = $newObject;

因为每个$object都是对象而不是数组。向对象添加新属性是通过->完成的，而不是[]。

完整代码：

function appendToArray($arrayOfObjects) {

    foreach ($arrayOfObjects as $object) {
        echo "<pre>".print_r($object, true)."</pre>";

        $newItems = array('item1', 'item2', 'item3');
        $moreItems = array('more1', 'more2', 'more3');

        $newObject = array();
        $newObject["newItems"] = $newItems;
        $newObject["moreItems"] = $moreItems;

        $object->new_stuff = $newObject;
    }

    return $arrayOfObjects;
}

您可以array_walk并更改对象：

getComponent

将数组添加到现有对象
