各年のデータを5年間のグループに入れます

Question

5年のグループに分割された年のテーブルを生成するコードがあります。各年の各データをそれぞれの列にどのように置くのですか？

これは私が今までに得たものです。

$chunkSize = 5; 
    $starting_year = 2006; 
    $ending_year = date("Y"); 

    for($starting_year; $starting_year <= $ending_year; $starting_year++) { 
     $years[] = $starting_year; 
    } 

    for($i = 0; $i < count($years); $i+=5) 
    { 

     echo "<table class='table table-striped table-bordered'>"; 
     echo '<thead><tr>'; 
      echo '<th class="text-center">'.implode('<th class="text-center">', array_slice($years, $i, $chunkSize)).'</th>'; 
     echo '</tr></thead>'; 
      echo '<tr>'; 


    $result= $myDB->query("SELECT total FROM ".$myDB->prefix("statistics")." WHERE year='$years[$i]'") or die(mysql_error()); 
    $row = $myDB->fetchArray($result); 
     $total=$row['total']; 

     //echo "<td class='text-center'>".$total."</td>"; 
    echo '<th class="text-center">'.implode('<th class="text-center">', array_slice($total, $i, $chunkSize)).'</th>'; 


     echo '</tr>'; 



    } 
    echo "</table>"; 

電流出力

望ましい結果

2016 2017    
total total   
2011 2012 2013 2014 2015 
total total total total total 
2006 2007 2008 2009 2010 
total total total total total

<?php 
    $chunkSize = 5; 
    $starting_year = 2006; 
    $ending_year = date("Y"); 
    //create an array of years 
    $years = range($starting_year,$ending_year); 
    //[2006,2007,....,2016,2017] 

    //split years in required size 
    $chunked = array_chunk($years,$chunkSize); 
    //[ [2006,....,2010], [2011,...2015], [2016,2017]] 

    //reverse it 
    $reversed = array_reverse($chunked); 
    //[ [2016,2017], [2011,...2015], [2006,....,2010]] 

    echo "<table class='table table-striped table-bordered'><tbody>"; 
    foreach($reversed as $reverse) { 
    echo "<tr>"; 
    foreach($reverse as $year) { 
     echo "<th>{$year}</th>"; 
    } 
    echo "</tr><tr>"; 
    foreach($reverse as $year) { 
     $result= $myDB->query("SELECT total FROM ".$myDB->prefix("statistics")." WHERE year='{$year}'") or die(mysql_error()); 
     echo "<td>{$result['total']}</td>"; 
    } 
    echo "</tr>"; 
    } 
    echo "</tbody></table>"; 

コードがより最適化することができますが、これは仕事を行います。
