Steam Web API - парсинг JSON-результата GetUserStatsForGame

Я пытаюсь проанализировать входящий JSON из Steam Web API для отображения конкретной статистики из игры.В этом случае игра Rust.

JSON возвращается из API: 

{
"playerstats": {
    "steamID":"76561198288875739",
    "gameName":"",
    "stats":[
        {"name":"deaths","value":268},

        {"name":"topology_road_duration","value":785},
        {"name":"destroyed_barrels","value":113}
        ],
    "achievements":[
        {"name":"CONSTRUCT_BASE","achieved":1},
        {"name":"UPGRADE_BASE","achieved":1},
        {"name":"COLLECT_50_LGF","achieved":1},
        {"name":"COLLECT_300_METAL_ORE","achieved":1},
        {"name":"VISIT_ROAD","achieved":1},
        {"name":"COLLECT_65_SCRAP","achieved":1},
        {"name":"DESTROY_10_BARRELS","achieved":1}
        ]
    }
}

У меня возникли проблемы с использованием этих данных для отображения желаемой статистики.Например, я хочу отобразить общее количество убийств игроков ("name":"kill_player","value":296)

Как мне это удастся?Я уже анализировал несколько простых JSON, но ничего сложного.

Благодарю за помощь!

РЕДАКТИРОВАТЬ

Мне удалось получить все имена со всеми значениями, выполнив это: 

$rust_info_result = json_decode($rust_info_result);
$rust_info_result = $rust_info_result->playerstats->stats;

foreach($rust_info_result as $r2)
{
  echo $r2->name; echo " "; echo $r2->value; echo "<br>";
}

Но я все еще не могу найти способ получить детали для конкретной статистики.Например, kill_player.

EDIT # 2

Мне удалось заставить это работать.Для тех, у кого такая же проблема, как у меня, я обнаружил, что следующий метод отлично работает для меня: 

$rust_info_result = json_decode($rust_info_result);
$rust_info_result = $rust_info_result->playerstats->stats;

$stats = [];

foreach ($rust_info_result as $r2)
{
    $stats[$r2->name] = $r2->value;
}

echo "Player Kills: " . $stats['kill_player'];

Вам нужно перебрать массив элементов, чтобы найти тот, который имеет name, который вы ищете.К сожалению, нет встроенного, чтобы сделать это для вас. 

<?php

$json = '{
    "playerstats": {
        "steamID":"76561198288875739",
        "gameName":"",
        "stats":[
            {"name":"melee_strikes","value":1940},
            {"name":"melee_thrown","value":47},
            {"name":"placed_blocks","value":164},
            {"name":"upgraded_blocks","value":1050},
        ],
        "achievements":[
            {"name":"CONSTRUCT_BASE","achieved":1},
            {"name":"UPGRADE_BASE","achieved":1},
        ]
    }
}';

function getStat(string $name, array $from): float
{
    foreach ($from['playerstats']['stats'] as $item) {
        if (isset($item['name']) && isset($item['value']) && $item['name'] === $name) {
            return $item['value'];
        }
    }
    return -1;
}

function getAchievement(string $name, array $from): float
{
    foreach ($from['playerstats']['achievements'] as $item) {
        if (isset($item['name']) && isset($item['achieved']) && $item['name'] === $name) {
            return $item['achieved'];
        }
    }
    return -1;
}

$dec = json_decode($json, true);

echo 'upgraded_blocks: ' . getStat('upgraded_blocks', $dec) . PHP_EOL;
echo 'CONSTRUCT_BASE: ' . getAchievement('CONSTRUCT_BASE', $dec) . PHP_EOL;

Я написал несколько очень простых вспомогательных функций, которые сделают эту работу за вас.Они вернут -1, если вы введете несуществующую статистику или имя достижения (или если оно не написано с учетом строчных и прописных букв).
