php常见分页有3种,一种是文字分页,比如说上一页,下一页之类的,还有一种数字分页,像1,2,3...之类的,这个比较简单,前者稍微复杂些.最后一种是他们2者结合.

下面是代码:

 1 //获取当前页数
 2         if(isset($_GET['page'])){
 3             $page = intval($_GET['page']);
 4         }
 5         else {
 6             $page=1;
 7         }
 8         $PageSize = 1//每页的记录数量
 9         // 获取总数量
10         $sql = "select count(*) from blog";
11         $result = mysql_query($sql);
12         $row = mysql_fetch_row($result);
13         $amount = $row[0];
14         /*计算总页数
15         if($amount){
16             if($amount 17                 $PageCount = 1;
18             }
19             if($amount%$PageSize) { //总数量除以每页的记录数量取于
20                 $PageCount =& amp;nbsp;(int)($amount/$PageSize)+1;//如果有于,则页数等于总数量除每页的记录数加1
21             }
22             else{
23                 $PageCount =& amp;nbsp;$amount/$PageSize;//没有,则结果是页数
24             }
25         }
26         else{
27             $PageCount = 0;
28         }*/
29         $PageCount = ceil($amount/$PageSize);//总页数=总数量除以每页数量  如果有小树,则进位
30         if($Page>$PageCount|$page==0){// 如果当前页数大于总页数
31             echo "不能发现此页!";
32             exit();
33         }
34       
35         //翻页链接
36         $PageOut = '';
37         if($page==1){//如果页数只有一页
38             $PageOut .= '第一页|上一页';
39         }
40         else{
41             $PageOut .= '第一页& lt;/a>|'.($page-1).'">上一页|';
42         }
43         if($page==$PageCount||$PageCount==0){//如果当前页等于总也数
44             $PageOut .= '下一页|尾页';
45         }
46         else{
47             $PageOut .=  ''.($page+1).'">下一 页|'.$PageCount.'">尾页';
48         }
49         //获取数据
50         if($amount){
51         $sql="select * from blog limit ".($page-1)*($PageSize).",$PageSize";
52         $result=mysql_query($sql);
53         while($row=mysql_fetch_array($result)){//此段代码只是示例
54             $blogs[] = array('bid'=>$row['bid'],'title'=>$row['title']);
55             foreach ($blogs as $blog){
56             $title=$blog['title'];
57             }
58             $output = "$blog[bid]>删除".
59             "$blog[bid]>编辑".
60             "$blog[bid]>查看";
61             include("template/default/blog.tpl.php");
62             echo $PageOut;
63         }
64         for($i=1;$i$PageCount;$i++){//数字分页
65            $Pageshow = ($i!=$page)?"".$i."'>$i":"$i";
66            echo $PageShow;
67          }
68          echo $amount.'条记录,每页'.$PageSize.'条,共'.$PageCount.'';
69         }

When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4.

Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
