Question

我正在尝试在php中显示JSON数组

JSON：

我希望能够以“position”变量的数字顺序显示它，其中头像位于用户名旁边，然后是游戏文本。

HTML布局：

 <img src="AVATAR_URL" width="50%"> USERNAME - <small>GAME</small><br>

$arr=json_decode($data,true);

echo '<img src="'.$val['avatar_url'].'" width="50%"> '.$val['username'].' -  <small>'.$gmtxt.'</small><br>';
}

Answer 2

试试这段代码兄弟，希望有所帮助

$arr=json_decode($data,true);
// to prevent error undefined index
if(isset($arr['members'])) {
  foreach($arr['members'] as $val){
    $gmtxt=isset($val['game']['name'])?$val['game']['name']:"";
    echo '<img src="'.$val['avatar_url'].'" width="50%"> '.$val['username'].' -  <small>'.$gmtxt.'</small><br>';
  }
}
