PHP分页分离

Question

我是PHP的初学者。生成分页我有100多页，而且他们占据了大量的空间，有助于确保你可以做这样的事情：

与分离...和按钮：第一个和最后一个页。

我的代码是

<div class="span12"> 
<?php 
$num_pages = 0; 
$per_pages = 2; 
echo <<<EOF 
<span class="active"><a href="index.php">1</a></span> 
EOF; 
do{ 
echo <<<EOF 
<span class="pagination"><a href="index.php?num={$per_pages}">{$per_pages}</a></span> 
EOF; 
$per_pages = $per_pages + 1; 
$num_pages++; 
} 
while ($num_pages <= 100); 
echo "\r\n"; 
?> 
</div> 
<?php echo "\r\n"; ?>

只是一个快速逼近

<div class="container" > 

<?php 
/* 
    Here you should fetch your pages from your DB or whatever you're using 
*/ 
$num_pages = 50; 
$num_paginations = ceil($num_pages/20); 
$current_pagination = 0; 
$current_page = 0; 
$prev_page = 0; 
$next_page = 0; 

if(isset($_GET['page'])){ 

    $current_page = $_GET['page']; 
    $prev_page = $current_page-1; 
    $next_page = $current_page+1; 
    for ($i=1; $i <= $num_paginations ; $i++) { 
     if($current_page/(20*$i) < 1){ 
      $current_pagination = $i; 
      break; 
     } 
    } 
} 

if (isset($_GET['page']) && $_GET['page'] > 0 && $_GET['page'] <= $num_pages) 
{ 

?> 
<ul class="pagination"> 
    <li><a <?php echo 'href="pagination.php?page='.$prev_page.'"';?> >&laquo;</a></li> 
    <?php 
    $initial_number = $current_pagination*20-19; 
    $final_number = $current_pagination*20; 
    $j = 1; 
    for ($i=$initial_number; $i <=$final_number; $i++) { 

     if($j <= 5 || $j == 20 || $j == 19){ 
     ?> 

      <li <?php 

      if($i == $current_page) echo ' class="active"'; 
      if($i > $num_pages){ 
       echo ' class="disabled"'; 
       ?> 
       ><a> <?php echo $i; ?></a> 
       <? 
       continue; 
      } 

      ?>> 
       <a <?php echo 'href="pagination.php?page='.$i.'"';?> > <?php echo $i; ?></a>   
      </li> 
     <? 
     } 
     if($j == 6){ 
     ?> 
      <li class="disabled"><a>...</a></li> 
     <? 
     } 
     $j++; 
    } 

    ?> 
    <li><a <?php echo 'href="pagination.php?page='.$next_page.'"';?> >&raquo;</a></li> 
</ul> 
<?php 
}else{ 
    ?> 
    <h2>Page doesn't exist!</h2> 
    <? 
} 
?> 

</div>
