无法将JSON响应处理为array（）变量

Question

im stuck in getting json response to array variables in my code so
1. The thing that i make work is pure JSON from link:

    {"39766855": "id":39766855,"name":"MCNoAd","profileIconId":779,"summonerLevel":30,"revisionDate":1432371417000}}

My code:

    $KEY = "<my key>"; //hidden for security
    $url='https://eune.api.pvp.net/api/lol/eune/v1.4/summoner/by-name/'.$summoner.'?api_key='.$KEY;
    $data=file_get_contents($url);
    $json=json_decode($data);
    $lol_summoner_array = (array) $json; // dont know if it is a best method but it do the work

    $id = $lol_summoner_array[$summoner]->id; //set for future use

And now i can call the response values by:

$lol_summoner_array[$summoner]->summonerLevel // output: 30
$lol_summoner_array[$summoner]->name // output MCNoAd 

it works good but i can't handle with my following code : 1st. my json response is like:

    {"summonerId":39766855,"playerStatSummaries":[{"playerStatSummaryType":"CoopVsAI","wins":56,"modifyDate":1423415169000,"aggregatedStats":{"totalChampionKills":304,"totalMinionKills":4541,"totalTurretsKilled":80,"totalNeutralMinionsKilled":158,"totalAssists":506}},{"playerStatSummaryType":"Unranked3x3","wins":4,"modifyDate":1423415169000,"aggregatedStats":{"totalChampionKills":26,"totalMinionKills":474,"totalTurretsKilled":3,"totalNeutralMinionsKilled":11,"totalAssists":43}},{"playerStatSummaryType":"RankedSolo5x5","wins":15,"losses":29,"modifyDate":1430810672000,"aggregatedStats":{"totalChampionKills":100,"totalMinionKills":2239,"totalTurretsKilled":20,"totalNeutralMinionsKilled":147,"totalAssists":501}},{"playerStatSummaryType":"OdinUnranked","wins":3,"modifyDate":1431076606000,"aggregatedStats":{"totalChampionKills":32,"totalAssists":37,"maxChampionsKilled":7,"averageNodeCapture":7,"averageNodeNeutralize":5,"averageTeamObjective":1,"averageTotalPlayerScore":854,"averageCombatPlayerScore":207,"averageObjectivePlayerScore":648,"averageNodeCaptureAssist":0,"averageNodeNeutralizeAssist":2,"maxNodeCapture":10,"maxNodeNeutralize":8,"maxTeamObjective":1,"maxTotalPlayerScore":1147,"maxCombatPlayerScore":298,"maxObjectivePlayerScore":944,"maxNodeCaptureAssist":1,"maxNodeNeutralizeAssist":2,"totalNodeNeutralize":31,"totalNodeCapture":44,"averageChampionsKilled":4,"averageNumDeaths":7,"averageAssists":6,"maxAssists":10}},{"playerStatSummaryType":"CAP5x5","wins":68,"modifyDate":1431585301000,"aggregatedStats":{"totalChampionKills":541,"totalMinionKills":9928,"totalTurretsKilled":100,"totalNeutralMinionsKilled":828,"totalAssists":1991}},{"playerStatSummaryType":"CounterPick","wins":0,"modifyDate":1431689669000,"aggregatedStats":{"totalChampionKills":1,"totalMinionKills":31,"totalTurretsKilled":0,"totalNeutralMinionsKilled":0,"totalAssists":12}},{"playerStatSummaryType":"AramUnranked5x5","wins":40,"modifyDate":1432364514000,"aggregatedStats":{"totalChampionKills":543,"totalTurretsKilled":29,"totalAssists":1797}},{"playerStatSummaryType":"URF","wins":14,"modifyDate":1432364514000,"aggregatedStats":{"totalChampionKills":120,"totalMinionKills":1598,"totalTurretsKilled":32,"totalNeutralMinionsKilled":55,"totalAssists":224}},{"playerStatSummaryType":"Unranked","wins":146,"modifyDate":1432371416000,"aggregatedStats":{"totalChampionKills":1327,"totalMinionKills":26048,"totalTurretsKilled":252,"totalNeutralMinionsKilled":365,"totalAssists":2976}}]}

And my php is:

$url2='https://eune.api.pvp.net/api/lol/eune/v1.3/stats/by-summoner/'.$id.'/ranked?api_key='.$KEY;
$data2=file_get_contents($url2);
$json2=json_decode($data2);
$lol_stats_array = (array) $json2;
echo '<br> test:'.$lol_stats_array[$id][0]->totalSessionsPlayed .'<br>'; // outputs nothing

print_r($lol_stats_array); // output below

my array:

i'm trying to display specified data for example "totalSessionsPlayed" of champion id 76 what is correct ? i'v tried $lol_stats_array[$id][76]->totalSessionsPlayed but nothing work.

Answer 1

You will have to find the ID 76 from the champions list first, then you can get specific data from the filtered object. I have shown how to get totalSessionsPlayed here. You can find other field similar way.

foreach($lol_stats_array['champions'] as $stat_object) {

    if($stat_object->id == 76) {
      $totalSessionsPlayed = $stat_object->stats->totalSessionsPlayed;
    }
}
