Api array php

oui :/

$homep = '';

$arr = json_decode($homep, true);

foreach ($arr as $k=>$v){
echo $v;
}
sa m'affiche :
0 : Array
1 : Array
2 : Array
3 : Array
4 : Array
5 : Array
6 : Array
7 : Array
8 : Array
9 : Array

Fais donc un

print_r ($arr);

en faite avec ce json :
[{"playerId":51037035,"championId":12,"championLevel":5,"championPoints":58890,"lastPlayTime":1466737091000,"championPointsSinceLastLevel":37290,"championPointsUntilNextLevel":0,"chestGranted":true,"tokensEarned":0},{"playerId":51037035,"championId":21,"championLevel":5,"championPoints":44974,"lastPlayTime":1459357838000,"championPointsSinceLastLevel":23374,"championPointsUntilNextLevel":0,"chestGranted":false,"tokensEarned":0},{"playerId":51037035,"championId":236,"championLevel":5,"championPoints":42983,"lastPlayTime":1465661615000,"championPointsSinceLastLevel":21383,"championPointsUntilNextLevel":0,"chestGranted":false,"tokensEarned":0},{"playerId":51037035,"championId":89,"championLevel":5,"championPoints":41534,"lastPlayTime":1463855929000,"championPointsSinceLastLevel":19934,"championPointsUntilNextLevel":0,"chestGranted":false,"tokensEarned":0},{"playerId":51037035,"championId":429,"championLevel":5,"championPoints":40801,"lastPlayTime":1465988670000,"championPointsSinceLastLevel":19201,"championPointsUntilNextLevel":0,"chestGranted":false,"tokensEarned":0},{"playerId":51037035,"championId":222,"championLevel":5,"championPoints":37471,"lastPlayTime":1465270736000,"championPointsSinceLastLevel":15871,"championPointsUntilNextLevel":0,"chestGranted":false,"tokensEarned":0},{"playerId":51037035,"championId":104,"championLevel":5,"championPoints":34852,"lastPlayTime":1462895569000,"championPointsSinceLastLevel":13252,"championPointsUntilNextLevel":0,"chestGranted":true,"tokensEarned":0},{"playerId":51037035,"championId":67,"championLevel":5,"championPoints":28673,"lastPlayTime":1467318064000,"championPointsSinceLastLevel":7073,"championPointsUntilNextLevel":0,"chestGranted":false,"tokensEarned":0},{"playerId":51037035,"championId":9,"championLevel":5,"championPoints":28153,"lastPlayTime":1455197642000,"championPointsSinceLastLevel":6553,"championPointsUntilNextLevel":0,"chestGranted":false,"tokensEarned":0},{"playerId":51037035,"championId":133,"championLevel":5,"championPoints":24081,"lastPlayTime":1453493846000,"championPointsSinceLastLevel":2481,"championPointsUntilNextLevel":0,"chestGranted":false,"tokensEarned":0}]

j'aimerai recuperer tous les championid avec pour chaque championid ,le championpoint

@lightdevDans ce cas...

$arr = json_decode($homep, true);
foreach ($arr as $c){
    echo $c['championId'] . " " . $c['championPoints'] . "<br>\n";
}

grand merci :)
