如何从另一个数组中的数组中获取数据？

  • 772

我想访问时间、home_scorer、score、away_scorer，但我不能给它：/谢谢你的帮助！

[

    {

        "match_id":"119596",
        "country_id":"169",
        "country_name":"England",
        "league_id":"62",
        "league_name":"Premier League",
        "match_date":"2016-10-30",
        "match_status":"FT",
        "match_time":"18:00",
        "match_hometeam_name":"Southampton",
        "match_hometeam_score":"0",
        "match_awayteam_name":"Chelsea",
        "match_awayteam_score":"2",
        "match_live":"1",
        "goalscorer": [
            {
                "time":"6'",
                "home_scorer":"",
                "score":"0 - 1",
                "away_scorer":"E.  Eden Hazard"
            },
            {
                "time":"55'",
                "home_scorer":"",
                "score":"0 - 2",
                "away_scorer":"D.  Diego  Costa"
            }
        ]
    }
]

    假设您将数组存储在名为 的变量中$array，因此您应该访问数组的第一个位置，goalscorer如下所示：

    $goalscorer = $array[0]["goalscorer"];

    这样我们就得到了数组goalscorer。

    稍后我们可以通过循环遍历数组的每个对象foreach：

    foreach($goalscorer as $goal){
    echo $goal["time"];
    echo $goal["home_scorer"];
    echo $goal["score"];
    echo $goal["away_scorer"];
}

    永远记住，数组是使用方括号在 JSON 中定义的，而数组中定义的[]每个对象都使用花括号{}。

  2. 由于是JSON格式的数组，所以首先要解码成PHP可以使用的数组，如下：

    $startArray = json_decode('[{
                        "match_id":"119596",
                        "country_id":"169",
                        "country_name":"England",
                        "league_id":"62",
                        "league_name":"Premier League",
                        "match_date":"2016-10-30",
                        "match_status":"FT",
                        "match_time":"18:00",
                        "match_hometeam_name":"Southampton",
                        "match_hometeam_score":"0",
                        "match_awayteam_name":"Chelsea",
                        "match_awayteam_score":"2",
                        "match_live":"1",
                        "goalscorer": [{
                            "time":"6\'",
                            "home_scorer":"",
                            "score":"0 - 1",
                            "away_scorer":"E.  Eden Hazard"
                        },{
                            "time":"55\'",
                            "home_scorer":"",
                            "score":"0 - 2",
                            "away_scorer":"D.  Diego  Costa"
                        }]
        }]');
$array = json_decode('$array');

    之后，您可以在占用它时访问它的元素和属性：

    $goalscorer = $array[0]->goalscorer;
//var_dump($goalscorer);
foreach($goalscorer as $goal){
    echo $goal->time."<br>";
    echo $goal->home_scorer."<br>";
    echo $goal->score."<br>";
    echo $goal->away_scorer."<br>";
}

    我使用它的原因->是因为在执行该函数时json_decode()，数组被转换为一个对象，因此为了访问它的属性，您必须使用该表示法而不是传统的 box 表示法[]。

    注意：我\在属性中使用的原因time是因为否则 PHP 会认为我正在关闭那里的 JSON 字符串并在编译时会发送错误。
