我无法从JSON获取数据。
我正在为我从API获得的json格式数据做一个foreach（），但是我无法让它工作。
这是我的代码：
$ player_runes是数据库变量，它完全正常，我的问题是获取每个数组（页面）的runeID数据
foreach($player_runes->pages as $statplayerrunesfor){
$statplayerrunesforune0 = $statplayerrunesfor->slots->runeId;
echo $statplayerrunesforune0;
}
这是JSON数据：

它应该适合你：
$player_runes = json_decode($variable_with_json, true);
foreach($player_runes['pages'] as $statplayerrunesfor){
$statplayerrunesforune0 = $statplayerrunesfor['slots']['runeId'];
echo $statplayerrunesforune0;
}
解码后，它变为array而不是对象。

试试这个：
foreach(json_decode($player_runes->pages) as $statplayerrunesfor){
$statplayerrunesforune0 = $statplayerrunesfor->{'slots'}->{'runeId'};
echo $statplayerrunesforune0;
}
希望它有效：）
