在PhP中限制分页页面 [英] Limit Pagination pages in PhP

问题描述

我在自己的网站上有一个哈希数据库，因此我想进行分页(因为210.000哈希值不降低网站速度就不会轻易加载)

I have a hash database on my own site, and I wanted to paginate (because 210.000hashes won't load easily without slowing down the site)

现在我已经对我的书进行了分页，但是我得到了大约21.000页 如何将其限制为大约100页??

now I have paginated my stuff, but I get about 21.000 pages how can I limit this to about 100pages???

$sql = "SELECT * FROM hashes";
$rs_result = mysql_query($sql); //run the query
$total_records = mysql_num_rows($rs_result);  //count number of records
$total_pages = ceil($total_records / $num_rec_per_page); 

echo "<a href='?page=1'>".'|<'."</a> "; // Goto 1st page  

for ($i=1; $i<=$total_pages; $i++) { 
        echo "<a href='?page=".$i."'>".$i."</a> "; 
}; 
echo "<a href='?page=$total_pages'>".'>|'."</a> "; // Goto last page

请不要介意我制作的糟糕方法，我只是想让它工作，而不是看起来很漂亮:)

Please don't mind the crappy way I made it, I just want it to work, not look pretty :)

推荐答案

在PHP中分页

将每页的项目数限制为

Limit the number of items per page by

if(isset($_GET['page']))
    $page=$_GET['page'];
else 
    $page=1;

$max_results=6;
$from=( ($page * $max_results) - $max_results);     

在此情况下，每页限制6($max_results=6;)个项目您可以更改 根据您的需要

in this i limit 6($max_results=6;) items per page you can change according to your need

使用查询限制结果

$search=mysql_query("SELECT * FROM `hashes` LIMIT $from,$max_results"); 
$total_results=mysql_result(mysql_query("select count(*) as num from `hashes`"),0);
while($r=mysql_fetch_object($search))
{//your code}

提供页面链接的分页概念

Pagination concept to provide links for pages

$total_pages=ceil($total_results/$max_results);
if($total_results>$max_results)
{
if($page>1)
{
    $prev=($page-1);
    echo "<a href=\"".$_SERVER['PHP_SELF']."?page=$prev\" style='text-decoration:none'>&nbsp;<< Previous&nbsp;</a>";
}
for($i=1;$i<=$total_pages;$i++)
{
    if($page==$i)
    {
        echo $i."";
    }
    else
    {
        echo "<a href=\"".$_SERVER['PHP_SELF']."?page=$i\" style='text-decoration:none'>&nbsp;$i&nbsp;</a>";
    }
}
if($page<$total_pages)
{
    $next=($page+1);
    echo "<a href=\"".$_SERVER['PHP_SELF']."?page=$next\" style='text-decoration:none'>&nbsp;Next>></a>";
}
}
