【问题描述】：

我尝试使用 steam api，我调用了一个响应并通过代码对其进行了格式化：

$url = 'http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key='.$key.'&steamids='.$id;

$json = json_decode(file_get_contents($url));
$steam_array = (array) $json;

$json 的 print_r：

stdClass Object ( [response] => stdClass Object ( [players] => Array ( [0] => stdClass Object ( [steamid] => 76561198092269637 [communityvisibilitystate] => 3 [profilestate] => 1 [personaname] => NoAd [lastlogoff] => 1527501715 [profileurl] => https://steamcommunity.com/id/noad/ [avatar] => https://steamcdn-a.akamaihd.net/steamcommunity/public/images/avatars/29/29f37f0a8b3b1d3dd0d7bb4c19f6bded0a417cad.jpg [avatarmedium] => https://steamcdn-a.akamaihd.net/steamcommunity/public/images/avatars/29/29f37f0a8b3b1d3dd0d7bb4c19f6bded0a417cad_medium.jpg [avatarfull] => https://steamcdn-a.akamaihd.net/steamcommunity/public/images/avatars/29/29f37f0a8b3b1d3dd0d7bb4c19f6bded0a417cad_full.jpg [personastate] => 1 [realname] => Adam Nowak [primaryclanid] => 103582791429521408 [timecreated] => 1369457346 [personastateflags] => 0 [loccountrycode] => PL [locstatecode] => 35 [loccityid] => 35736 ) ) ) )

$steam_array 的 print_r

Array ( [response] => stdClass Object ( [players] => Array ( [0] => stdClass Object ( [steamid] => 76561198092269637 [communityvisibilitystate] => 3 [profilestate] => 1 [personaname] => NoAd [lastlogoff] => 1527501715 [profileurl] => https://steamcommunity.com/id/noad/ [avatar] => https://steamcdn-a.akamaihd.net/steamcommunity/public/images/avatars/29/29f37f0a8b3b1d3dd0d7bb4c19f6bded0a417cad.jpg [avatarmedium] => https://steamcdn-a.akamaihd.net/steamcommunity/public/images/avatars/29/29f37f0a8b3b1d3dd0d7bb4c19f6bded0a417cad_medium.jpg [avatarfull] => https://steamcdn-a.akamaihd.net/steamcommunity/public/images/avatars/29/29f37f0a8b3b1d3dd0d7bb4c19f6bded0a417cad_full.jpg [personastate] => 1 [realname] => Adam Nowak [primaryclanid] => 103582791429521408 [timecreated] => 1369457346 [personastateflags] => 0 [loccountrycode] => PL [locstatecode] => 35 [loccityid] => 35736 ) ) ) )

如何在其中一个混乱中调用变量？如果我使用 var_dump($json) 它离开类。

我试过了：

echo $steam_array->value["players"][0]['avatarfull'];   
echo $steam_array->value["avatarfull"];

我还不熟悉 php 中的类和对象：/

我想要这样的

$steam_array[0]['avatarfull'];

[0] 很重要，因为这个 api 请求可以捕获多个人

【解决方案1】：

您好$steam_array 是一个数组，您将其称为对象，因此请像数组一样将其称为数组，请在下方查看。

$steam_array['response']->players[0]->steamid

steamid 还有你的所有领域。
