问题描述
我很难从JSON获取数据.
I am having difficulty getting data from JSON.
我对从API获得的json格式数据进行了foreach()处理后，但无法正常工作.
I am after doing a foreach() for json formatted data that I get from a API, but I cant get it to work.
这是我的代码:
$ player_runes是数据库变量，它完全可以正常工作，我的问题是获取每个数组(页面)的runeID数据
The $player_runes is the database variable, it works totally fine, my problem is getting the data of runeID for each Array (pages)
foreach($player_runes->pages as $statplayerrunesfor){
$statplayerrunesforune0 = $statplayerrunesfor->slots->runeId;
echo $statplayerrunesforune0;
}
这是JSON数据:

推荐答案
尝试一下:
foreach(json_decode($player_runes->pages) as $statplayerrunesfor){
$statplayerrunesforune0 = $statplayerrunesfor->{'slots'}->{'runeId'};
echo $statplayerrunesforune0;
}
希望它能起作用:)
