如何使用 file_get_contents 从数组中获取特定字段

Question

我想获取玩家字段：

例如 id、名称、标签、平台等

我有这种类型的数据：

stdClass Object
(
    [player] => stdClass Object
        (
            [id] => 179203896
            [game] => bf4
            [plat] => pc
            [name] => HeLLTiMe
            [tag] => DK
            [dateCheck] => 1391437377733
            [dateUpdate] => 1391437377733
            [dateCreate] => 1386696304438
            [lastDay] => 20140117
            [country] => 
            [countryName] => 
            [rank] => stdClass Object
                (
                    [nr] => 73
                    [imgLarge] => bf4/ranks/r73.png
                    [img] => r73
                    [name] => Chief Warrant Officer Five III
                    [needed] => 4920000
                    [next] => stdClass Object
                        (
                            [nr] => 74
                            [img] => r74
                            [name] => Chief Warrant Officer Five IV
                            [needed] => 5030000
                            [curr] => 5022060
                            [relNeeded] => 110000
                            [relCurr] => 102060
                            [relProg] => 92.781818181818
                        )

                )

            [score] => 5025100
            [timePlayed] => 862027
            [uId] => 2832659368608119092
            [uName] => HeLLTiMe
            [uGava] => 0b8b00021ebfb32414e5a6051c2c9a40
            [udCreate] => 1328606863000
            [blPlayer] => http://battlelog.battlefield.com/bf4/soldier/HeLLTiMe/stats/179203896/pc/
            [blUser] => http://battlelog.battlefield.com/bf4/user/HeLLTiMe/
            [editable] => 
            [viewable] => 1
            [adminable] => 
            [linked] => 
        )

    [stats] => stdClass Object
        (
            [reset] => stdClass Object
                (
                    [lastReset] => 0
                    [score] => 0
                    [timePlayed] => 0
                    [timePlayedSinceLastReset] => 0
                    [kills] => 0
                    [deaths] => 0
                    [shotsFired] => 0
                    [shotsHit] => 0
                    [numLosses] => 0
                    [numWins] => 0
                )

如何获取这些数据？

这是我的代码：

<?php
$url = "http://api.bf4stats.com/api/playerInfo?plat=pc&name=HeLLTiMe";
$json = file_get_contents($url);

$data = json_decode($json);
echo "<pre>";
print_r($data);
?> 

Answer 1

要获得名称，您应该这样做：

echo $data->player->name;

你需要这个，因为你有一个stdClass Object

你也可以把 out 改成一个数组，你必须改变这个：

$data = json_decode($json);

到这里：

$data = json_decode($json, true);

当你做这个 chagne 时，你可以通过这个获得价值：

echo $data['player']['name'];

编辑

您可以在下面看到示例，这对我来说没有错误。

$url = "http://api.bf4stats.com/api/playerInfo?plat=pc&name=HeLLTiMe";
$json = file_get_contents($url);

echo 'Using stdClass Object option<br>';
$data = json_decode($json);
echo $data->player->name;

echo '<br><br>Using Array option<br>';
$data = json_decode($json, true);
echo $data['player']['name'];

exit;

Answer 2

$result = array();

$result['name'] = $data->Player->name

var_dump($result);

Answer 3

不知道获取已经获取的数据是什么意思，但如果你问如何访问这些字段，你可以这样做。

print_r($data->player->name);
