php - 使用 PHP 循环遍历多维数组

问题描述

我正在尝试学习 php 并与 API 交谈以检索我的 Destiny 2 部落的信息。我已检索到所需的所有信息，并使用以下格式构建了一个新数组：

Array
(
    [displayname] => Senaxx
    [membershipId] => 4611686018428643772
    [characterdetails] => Array
        (
            [0] => Array
                (
                    [2305843009260824684] => Array
                        (
                            [characterlevel] => 30
                            [light] => 384
                            [datelastplayed] => 2018-08-19T13:23:27Z

这些只是 2 个玩家阵列。我的整个代码有 8 个。但对于这个例子，我认为其中 2 个就足够了。

我的目标是遍历数组并检索每个显示名称的所有玩家信息。

所以我从完美的开始：

foreach($claninfo as $clanmember)
{
 echo $clanmember['membershipId']; 
}

可悲的是，仅抓住角色细节对我来说是行不通的。mee 的问题似乎是有一个未知数字的额外 characterId。

foreach($claninfo as $clanmember)
{
 echo $clanmember['membershipId']; 
    foreach($claninfo->characterdetails as $characterdetails)
    {
      echo $characterdetails-> light;
    } 
}

最终目标是创建一个包含一些信息的表格：

<table>
<tbody>
<tr>
<td>Displayname</td>
<td>Playtime</td>
<td>Character 1</td>
<td>Character 2</td>
<td>Character 3</td>
</tr>
<tr>
<td>Senaxx</td>
<td>&nbsp;</td>
<td>light 384</td>
<td>light 394</td>
<td>light 394</td>
</tr>
<tr>
<td>Base1981</td>
<td>&nbsp;</td>
<td>light 358</td>
<td>light 100</td>
<td>light&nbsp;350</td>
</tr>
</tbody>
</table>

解决方案

直到灯的关联数组键是： $claninfo[<some key or index>]['characterdetails'][<Array Index>][<character id>]['light']

因此，要访问光，您需要使用foreach 3 次：

  1. 从部落信息中获取部落成员

  2. 迭代 $clanmember['characterdetails']

  3. 摆脱字符ID

    foreach($claninfo as $clanmember)
{
    echo $clanmember['membershipId']; 


   foreach($clanmember['characterdetails'] as $characterArray)
    {

       foreach($characterArray as $characterid => $characterdetails)
       { // You can access $characterid in this block
           echo $characterdetails['light'];
       } 
    } 
}
