Question

我想在php中对这个json数组进行排序，但我无法弄清楚如何去做。我想要最新一季和最新一集1，最新一季最新第1集2等等。

$episodelist = json_decode(file_get_contents('cache/episodes.json'), true);
$episodes = $episodelist["doctor who (2005)"];

json数组：

"doctor who (2005)": {
        "1": {

Answer 1

您希望通过usort()实施自定义排序。有点像这样：

$episodelist = json_decode(file_get_contents('cache/episodes.json'), true);

foreach ($episodelist as &$show) {
    usort($show, function ($a, $b) {
            if ($a["season"] == $b["season"]) {
                if ($a["episode"] == $b["episode"]) {
                    return 0;
                }
                return ($a["episode"] > $b["episode"]) ? -1 : 1;
            }
            return ($a["season"] > $b["season"]) ? -1 : 1;
        }
    );
}

var_export($episodelist);

输出：

array (
    'doctor who (2005)' =>
        array (
            0 =>
                array (

Answer 2

我认为您希望usort()具有以下comperator函数：

usort($array, function($a, $b){
    return $a['season'] * 1000 + $a['episode'] < $b['season'] * 1000 + $b['episode'] ? 1 : -1;
});

说明

usort函数使用提供的函数作为比较器来决定哪个元素是第一个。这样它就可以命令所有元素。我不确定你是否必须扭转它。如果是这种情况，只需将<替换为>即可。我使用因子1000使季节参数比剧集参数更强。我假设每个赛季的节目数不会超过999集。

当然，您需要使用json_decode将json字符串转换为php数组。
