PHPのページング列と行の発行

Question

Stackerで何十件もの質問を見てきましたが、おそらくページネーションの是正策を検討するときに何か不足しています。

5行に4行の20個のレコードを表示し、ボトムに「次へ」/「プリーブ」ボタンを表示したいとします。

なんらかの理由で、$ rowperpage = 5が1行5列になります。数字を大きくすると、別の列が追加されます。つまり、テーブルが伸びます。

実際のページネーションは（ページ1,2,3,4 ...まで）うまく機能しますが、列と行は連携していません。

希望の効果を達成するためのアイデアはありますか？

ここで私が使用しているコードです：あなたがすることができ任意の助け

<?php

$numrows = $r[0]; 

// number of rows to show per page 

$rowsperpage = 5; 
// find out total pages 
$totalpages = ceil($numrows/$rowsperpage); 

// get the current page or set a default 
if (isset($_GET['currentpage']) && is_numeric($_GET['currentpage'])) { 
    // cast var as int 
    $currentpage = (int) $_GET['currentpage']; 
} else { 
    // default page num 
    $currentpage = 1; 
} // end if 

// if current page is greater than total pages...

は、私はあなたが探しているものを行う必要があります

$rows_counter = 0; 
while ($list = mysql_fetch_assoc($result)) { 
    echo "<td align='center' style='height: 250px'>" . $list['name'] . "<br /><a href='http://www.snarrf.com/onsale/detail.php?id=" . $list['id'] . "'><img src='http://www.snarrf.com/onsale/nooks/" . $list['picture'] . "'  height='100' width='100' border='0' /></a><br />" . $list['address1'] ."</td>" ; 
    if (!(++$rows_counter % 5) and $rowsperpage != $rows_counter) 
     echo "</tr><tr>"; 
} 

で

while ($list = mysql_fetch_assoc($result)) { 
    echo "<td align='center' style='width: 800px; height: 250px'>" . $list   ['name'] . "<br /><a href='http://www.snarrf.com/onsale/detail.php?id=" . $list ['id'] . "'><img src='http://www.snarrf.com/onsale/nooks/" . $list['picture'] . "'  height='100' width='100' border='0' /></a><br />" . $list['address1'] ."</td>" ; 
}
