Question

我试图过滤JSON数组响应，因为我只需要一小部分结果。

我只需要让玩家displayName。

这是第一个玩家的休息，每场比赛最多可以有12个玩家。

我需要能够循环并提取名称的东西。

[displayName] => jonhofun

目前我能获得所需数据的唯一方法是做

$player1 = $json11['Response']['data']['entries']['0']['player']['destinyUserInfo']['displayName'];
$player2 = $json11['Response']['data']['entries']['1']['player']['destinyUserInfo']['displayName'];
etc... etc...

Answer 1

您需要在＆＃34;条目＆＃34;。

下循环子数组

foreach ($json11['Response']['data']['entries'] as $entries) {
    $player_names[] = $entries['player']['destinyUserInfo']['displayname'];
}

echo "<pre>";
print_r($player_names);    // Check all player names

Answer 2

使用for循环可以很容易地实现这一点，请查看以下示例，该示例可以让您了解如何继续：

// totalPlayers will need to be changed to the total number of entries you have
for ($x = 1; $x < $totalPlayers; $x++) {
    // You will need to do something with the nextPlayer here before the next iteration of the loop
    $nextPlayer = $json11['Response']['data']['entries'][$x]['player']['destinyUserInfo']['displayName'];
}

请注意，返回数据中的硬编码播放器标识符将替换为$x循环中的计数器for。
