Question

我遇到了问题，我正在尝试解析从网址动态更新的json文件。我遇到的第一个问题是，json文件只生成对象而没有数组（见ex.1）。

（例1）

[{"title":"ThisIsTitle1","Team1":"ThisIsTeam1","Team2":"ThisIsTeam2","Result":"ThisIsTeam1"}{"title":"ThisIsTitle2","TeamX":"ThisIsTeamX","TeamY":"ThisIsTeamY","Result":"ThisIsTeamY"}]

因为我不知道如何在没有数组的情况下解析字符串，所以我在网上查找了一下，找到了为每个对象动态添加数组的方法; （见ex.2＆amp; ex.3）

（例2）我上网的内容

$json_string = 'http://myurl/pathtojsonfile';  
$jsondata = file_get_contents($json_string);  
$obj = json_decode($jsondata,true);  
echo "<pre>";  
print_r($obj);

（ex.3）结果是什么

Array
(
    [0] => Array
        (
            [Title] => ThisIsTitle1
            [Team1] => ThisIsTeam1
            [Team2] => ThisIsTeam2
            [Result] => ThisIsTeam1
        )
    [0] => Array
        (
            [Title] => ThisIsTitle2
            [TeamX] => ThisIsTeamX
            [TeamY] => ThisIsTeamY
            [Result] => ThisIsTeamY
        )
)

现在这是我的问题：我正在尝试在同一个表格中显示所有TeamX和TeamY，并在其他单元格中添加其旁边的平均结果。表示每个团队的胜利和deafeat平均数。

你需要知道的事情：

由于json是动态生成的，因此团队可能（很可能）多次出现在json文件中。这意味着当您在同一个表中显示所有团队时，我们需要排除所有副本。
有时结果可能是：[Result] => ThisIsTeamZ;意味着团队中没有一个因某种原因获胜。

我知道我向你们提出了很多要求，但我是一个菜鸟，我学习起来很慢。如果你能帮助我，那么你会受到欢迎。如果你需要我的任何东西，请不要犹豫。

如果没有合适的JSON样本，我只能对您有权访问的实际数据格式做出假设。

您需要以可用的方式重新格式化该数据。例如，索引是团队的数组＆＃39;名称，值是包含相关值的索引victories，defeats和draws的数组。

这是通过循环JSON，检查哪个团队赢得了每个结果（如果有）并增加相关值（victories，defeats，draws）来完成的。< / p>

$teams = array();

foreach($obj as $result) {

    // team names
    $teamName1 = $result['team1'];
    $teamName2 = $result['team2'];

    // initialize team 1 array at zero if it does not exist
    if(!isset($teams[$teamName1])) {
        $teams[$result['team1']] = array('victories'=>0, 'defeats'=>0, 'draws'=>0);
    }

    // initialize team 2 array at zero if it does not exist
    if(!isset($teams[$teamName2])) {
        $teams[$teamName2] = array('victories'=>0, 'defeats'=>0, 'draws'=>0);
    }

    // team 1 wins
    if($result['Result'] == $teamName1) {
        $teams[$teamName1]['victories']++;
        $teams[$teamName2]['defeats']++;
    }
    // team 2 wins
    elseif($result['Result'] == $teamName2) {
        $teams[$teamName1]['defeats']++;
        $teams[$teamName2]['victories']++;
    }
    // draw
    else {
        $teams[$teamName1]['draws']++;
        $teams[$teamName2]['draws']++;
    }
}

然后您可以访问此结构，从而可以使用基本算法：

Array
(
    [ThisIsTeamX] => Array
        (
            [victories] => 98
            [defeats]   => 76
            [draws]     => 54
        )
    [ThisIsTeamY] => Array
        (
            [victories] => 12
            [defeats]   => 34
            [draws]     => 56
        )
)

你可以获得这样一支球队的胜利VS失败率：

$winRatio = $teams['ThisIsTeamX']['victories'] / $teams['ThisIsTeamX']['defeats'];

您可以获得此类团队所玩的比赛总数：

$matchesCount = array_sum($teams['ThisIsTeamX']);
