Question

这是我试图解析的JSON。

newdf.combine_first(pd.pivot_table(df,index='Date',columns='ID',values='Value',aggfunc='sum'))
Out[442]: 
          a     b
1/1/17  2.0   5.0
1/2/17  3.0  13.0
1/3/17  4.0   NaN

这是我试过的......

如果您可以先指导我显示内容，然后我就可以从那里开始尝试将所有内容放入表中。这很容易是java，但我以前从未尝试过在php中这样做。这对我来说是新的！

我没有得到的问题是我得到了KICKERS数组，然后将对象放入其中。但我有几个阵列。

非常感谢任何帮助。

您不能在内部$key循环中使用相同的foreach变量。此外，代码中的$value是一个播放器对象，无法直接回显。

如果在循环中使用更多描述性变量名称将会很有帮助，这样您就可以知道它们引用的数据结构的哪个部分。

例如：

foreach ($contentsDecoded as $position => $players) { 
     foreach($players as $player) {
         echo $player->nflPlayerName; 
    }
}

或者如果你特别想要踢球者：

foreach ($contentsDecoded->kickers as $kicker {
    echo $kicker->nflPlayerName;
}

通过JSON解析并显示在表中
