多维数组唯一PHP中的问题

你好。我正在使用

$manual['pages'] = array_map("unserialize", array_unique(array_map("serialize", $manual['pages'])));

在制作独特的is后，它会给我输出

{
"items": [
    {
        "manuals": [],
        "versions": [],
        "pages": {
            "0": {
                "id": "25",
                "short_title": "Windows 7 Software",
                "full_title": "Windows 7 Software",
                "image": "http://marksmith.biz/media/7.jpg",
                "tags": [
                    {
                        "name": "Software"
                    }
                ]
            },
            "1": {
                "id": "26",
                "short_title": "Software: The New Paint",
                "full_title": "Software: The New Paint",
                "image": "http://marksmith.biz/media/7.jpg",
                "tags": [
                    {
                        "name": "Software"
                    }
                ]
            },
            "2": {
                "id": "27",
                "short_title": "Software: The New Wordpad",
                "full_title": "Software: The New Wordpad",

                    }
                ]
            },
            "3": {
                "id": "28",
                "short_title": "Software: The New Calculator",
                "full_title": "Software: The New Calculator",
                "image": "http://marksmith.biz/media/7.jpg",
                "tags": [
                    {
                        "name": "Software"
                    }
                ]
            },
            "4": {
                "id": "29",
                "short_title": "Software: The New Word",
                "full_title": "Software: The New Word",
                "image": "http://marksmith.biz/media/7.jpg",
                "tags": [
                    {
                        "name": "Software"
                    }
                ]
            },
            "5": {
                "id": "30",
                "short_title": "Software: Windows Media Player 12",

                "tags": [
                    {
                        "name": "Software"
                    }
                ]
            },
            "7": {
                "id": "11",
                "short_title": "Software Compatibility",
                "full_title": "Software Compatibility",
                "image": "http://marksmith.biz/media/7.jpg",
                "tags": []
            }
        },
        "faqs": []
    }
],
"success": "true"

}

现在我的问题是你们可以看到pages数组。你们可以找到像0，1，2，3这样的数字。我想从数组中删除这些数字

任何帮助都将不胜感激

我找到了答案。只需使用数组_值，它就会从输出中删除

它们叫做索引。为什么要删除它们？你不需要。是的，我知道这些被称为索引，但我在angular JS中使用这个JSON，这给我带来了一些问题，所以我想删除这些索引。如果删除它们，你将如何遍历页面结果？如果您向我们展示用于读取JSON的代码，我们可能会提供更多帮助。
