自己写的php分页代码，喜欢的就看看，很实用的

function page_slice($total,$page,$page_size = '',$url = '',$max_length = '')
{
//$total :总数
//$page :传递过来的当前页的值,第八页$page = 8;
//$page_size :每页显示的数据的数目
//$url :传递的地址,默认为当前页面
//$max_length:分页代码时候,中间的分页数的一半
$page = ($page < 1) ? 1 : $page ;
$page_size = $page_size ? $page_size : 10;
$url = $url ? $url :$_SERVER['PHP_SELF'];
$max_length = $max_length ? $max_length : 5 ;
$start = $page ? ($page - 1) * $page_size : 0;
$total_page = ceil($total/$page_size);

$page_table = '';
//aways in the pages
$page_table = '<table id="page_slice"><tr>';
//显示第一页
if($page == 1 )
{
$page_table .= '<td class="current_page">1</td>';
}
else
{
$page_table .= '<td><a href="'.$url.'?page=1">[1]</a></td>';
}

//循环中间页码
if($total_page < $max_length*2)
{
$loop_start = 2;
$loop_end = $total_page-1;
}
else
{
$loop_start = $page - $max_length;
$loop_start = ($loop_start <2) ? 2 :$loop_start;
$loop_end = $page + $max_length;
$loop_end = ($loop_end < $max_length * 2) ? $max_length * 2:$loop_end;
$loop_end = ($loop_end > $total_page) ? $total_page-1 :$loop_end;

}

//... link
$link_start = (($loop_start - $max_length) < 2) ? 2 :$loop_start - $max_length;
$link_end = (($loop_end + $max_length) > $total_page) ? $total_page :$loop_end + $max_length;

if($loop_start > 2)
{
$page_table .= '<td><a href="'.$url.'?page='.$link_start.'">...</a></td>';
}

//中间链接
for($i = $loop_start ; $i <= $loop_end ; $i++)
{
if($page == $i)
{
$page_table .= '<td class="current_page">'.$i.'</td>';
}
else
{
$page_table .= '<td><a href="'.$url.'?page='.$i.'">['.$i.']</a></td>';
}
}
if($loop_end < $total_page-1)
{
$page_table .= '<td><a href="'.$url.'?page='.$link_end.'">...</a></td>';
}

//末页链接
if($total_page!=1)
{
if($page == $total_page)
{
$page_table .= '<td class="current_page">末页</td>';
}
else
{
$page_table .= '<td><a href="'.$url.'?page='.$total_page.'">[末页]</a></td>';
}
}
//输出分页代码
echo $page_table;
}
