在PHP中从JSON获取数据

I am trying to get the data out of this JSON format to be able to show on screen problem is I am not sure how I would be able to do this as I have tried multiple ways such as :

我试图从这个JSON格式获取数据,以便能够在屏幕上显示问题是我不知道我将如何做到这一点,因为我尝试了多种方式,如:

$stats = json_decode($result);
// var_dump($stats);
echo $stats->elo;

And nothing is working I am unsure how to get the data due to the [], as I have never worked with this before. As shown below is a small piece of the data I need to be able to get into.

没有什么工作我不确定如何获得由于[]的数据,因为我以前从未使用过这个。如下所示,我需要能够进入的一小部分数据。

[{"_id":{"championId":51,"role":"DUO_CARRY"},"elo":"BRONZE","patch":"7.11","championId":51,"positions":{"deaths":3,"winRates":6,"minionsKilled":2,"previousOverallPerformanceScore":6}}]

Thanks in advance

There is a simple rule of thumb when processing JSON. First just decode it and print it using a print_r() so you can see its structure easily

处理JSON时有一个简单的经验法则。首先解码它并使用print_r()打印它,这样您就可以轻松地看到它的结构

$s = '[{"_id":{"championId":51,"role":"DUO_CARRY"},"elo":"BRONZE","patch":"7.11","championId":51,"positions":{"deaths":3,"winRates":6,"minionsKilled":2,"previousOverallPerformanceScore":6}}]';

$stats = json_decode($s);

print_r($stats);

Which will show you in this case

这将在这种情况下向您展示

Array
(
    [0] => stdClass Object
        (
            [_id] => stdClass Object
                (
                    [championId] => 51
                    [role] => DUO_CARRY
                )
            [elo] => BRONZE
            [patch] => 7.11
            [championId] => 51
            [positions] => stdClass Object
                (
                    [deaths] => 3
                    [winRates] => 6
                    [minionsKilled] => 2
                    [previousOverallPerformanceScore] => 6
                )
        )
)

So now you know there is an array containing in this case only one object

所以现在你知道有一个数组在这种情况下只包含一个对象

So to show elo you could do a simple

所以要展示你好,你可以做一个简单的事情

echo $stats[0]->elo;    // BRONZE

But as it is an array of object it may be better to assume in some cases there will be more than one stat so you could process it in a foreach loop like this

但由于它是一个对象数组,最好假设在某些情况下会有多个统计信息,因此您可以在这样的foreach循环中处理它

foreach ($stats as $stat) {
    echo $stat->elo;
}
