通过for或foreach创建博客页面的算法

我尝试使用此算法创建一个简单的系统博客页面:

<?php
$page = floor(10 / 10);

$limit = 40;
$num= 100;
$page = 1;
for ($record = 0; $record <= $num ; ++$record ) 
{

   if($record % $limit == 0) 
   {
       if(!($record < $limit))
       {
           echo 'page:'.$page.'<br/>';
           for($id = $record - $limit +1 ; $id <= $record ; ++$id)
           {
               echo $id.'<br/>'; 
           }
           $page ++;
           echo '<hr>';
       }
   }
}
?>

但似乎不起作用例如......在$ limit = 40上我丢失了最后20个id!

可以帮助我改进此算法或建议我更好的方法&gt;

<?php
$limit = 40;
$items = 100;
$page_counter = 1;

$excess_items = $items % $limit;
if($excess_items > 0) 
    $total_page = ($items / $limit) + 1;


$current_count = 1;
while($page_counter <= $total_page){
    echo 'total_page:'.$page_counter.'<br/>';

    $cutting_count = 1;
    while($cutting_count <= $limit){
        if($current_count <= $items)
            echo $current_count.'<br/>'; 

        $cutting_count ++;
        $current_count ++;
    }
    echo '<hr>';
    $page_counter++;
}
?>
