访问php中没有键值的json数据

 echo "<table title='mxit:table:full' style='width: 100%' width='100%'><colgroup span='2' width='50%'></colgroup>";
 echo "<tr>";
 echo "<td align='center;' style='color:black;'>Rank</td>";
 echo "<td align='center;' style='color:black;'>Branch</td>";
 echo "</tr>";
$find = array_slice($_SESSION["data"], $rank - 2, 5);
foreach($find as $key => $element)
    {

    echo "<tr>";
    foreach($element as $subkey => $subelement)
        {
        echo $subelement;
        if ($subkey++ < 2)
            {

            if ($subkey == 1)
                {
                echo "<td align='center;' style='color:black;'>$subelement</td>";
                }
              else
                {
                echo "<td align='center;' style='color:black;'><a href='getdata.php?key=$key'>" . $subelement . "</a></td>";
                }
            }
        }
    echo "</tr>";
    }
echo "</table>";

我想使用一个密钥来获取数据，从某种意义上说，这个密钥就是排名。我面临的问题是我的数据中没有密钥。我使用等级作为完整数据显示的密钥，但在这种情况下，我不能这样做，因为我的密钥是0到5，而不是7到12

我的$find数组：

Array ( [0] => Array ( [0] => 7 [1] => KOTTAYAM TIEDAGENTSII [2] => V01393 - Venu M Nair [3] => R02208 - Reji Kumar [4] => 0.8854 [5] => 0.77570425252759 [6] => 1 [7] => 0.925 [8] => 0.9246 [9] => 1 [10] => 9.0926620166705 ) [1] => Array ( [0] => 8 [1] => PITAMPURA DLHI DIRECT [2] => C00405 - CHANDER MANI [3] => S00927 - Sachin Kumar [4] => 0.9478 [5] => 0.71204754186926 [6] => 0.94999999925494 [7] => 0.9845 [8] => 0.9692 [9] => 0.9400000013411 [10] => 9.0808534450678 ) [2] => Array ( [0] => 9 [1] => MUMBAI BHANDUP DIRECT [2] => B00841 - BHAVESH M KOTHARI [3] => A02234 - AMOL PRAKASH KANADE [4] => 0.9881 [5] => 1 [6] => 0.89000000059605 [7] => 0.9968 [8] => 1 [9] => 0.62000000476837 [10] => 9.0665850088513 ) [3] => Array ( [0] => 10 [1] => RATLAM DIRECT [2] => R01754 - Rajesh Joshi [3] => S03643 - Shishir Jain [4] => 1 [5] => 1 [6] => 0.74000000953674 [7] => 0.9779 [8] => 0.9902 [9] => 0.68999999761581 [10] => 8.9068650118017 ) [4] => Array ( [0] => 11 [1] => LUDHIANA DIRECT [2] => R02596 - RAKESH SHARMA [3] => J00753 - JAIPAL SINGH [4] => 1 [5] => 1 [6] => 0.72999998927116 [7] => 1 [8] => 0.9949 [9] => 0.65999999642372 [10] => 8.8850849763966 ) )

编辑：我的元素数组，我想让7，8，9作为数组的键，这样我就可以有效地使用它
