Question

我得到了一些xml格式的最新消息，并改为json格式，Android应用程序需要显示最新消息。我有一个以下的JSON数组...

{
    "rss_news": [
        {
            "title": " ",
            "rss_original_src": "recent_news1(google news)",
            "rss_original_src_img": "",
            "link": "",
            "pubDate": "Tue, 19 Apr 2016 14:05:47 +0530",
            "description": ""
        },
 {
            "title": " ",
            "rss_original_src": "recent_news2(yahoo news)",
            "rss_original_src_img": "",
            "link": "",
            "pubDate": "Tue, 19 Apr 2016 16:05:47 +0530",
            "description": ""
        },
 {
            "title": " ",
            "rss_original_src": "recent_news3",
            "rss_original_src_img": "",
            "link": "",
            "pubDate": "Tue, 19 Apr 2016 11:05:47 +0530",
            "description": ""
        },
....
]
}

现在我需要...基于值（pubDate）的PHP多维数组排序..

提前致谢..

首先使用usort($array, 'sortByDate'); function sortByDate($a, $b) { $date1=$a['pubDate']; $date2=$b['pubDate']; //return value based on above two dates. }将您的JSON字符串转换为PHP数组。

使用usort对数组进行排序，如。
