本文实例讲述了PHP分页显示的方法。分享给大家供大家参考,具体如下:

<"content-type:text/html;charset=utf-8");
$currentpage = 1;
if(isset($_GET['page']))
  $currentpage = $_GET['page'];
//连接数据库
$link = mysql_connect("localhost","root","") or die('连接失败');
mysql_select_db('myschool');
mysql_query('set names utf8');
$sql ="SELECT count(*) as 'count' from student";//查询记录的sql语句
$result = mysql_query($sql);
$arr = mysql_fetch_array($result);
$count = $arr['count'];
$pagesize = 3;
$pages = ceil($count/$pagesize);//共多少页
$prepage = $currentpage -1;
if($prepage<=0)
  $prepage=1;
$nextpage = $currentpage+1;
if($nextpage >= $pages){
 $nextpage = $pages;
}
$start =($currentpage-1) * $pagesize;//起始位置
$sql = "SELECT * from student limit $start,$pagesize";
echo $sql;
// $sql = "select * from student";
$result = mysql_query($sql);
"en">
<head>
 <meta charset="UTF-8">
 <title>Document</title>
</head>
<body>
<table border="1">
 <tr>
 <td>学号</td>
 <td>姓名</td>
 <td>性别</td>
 <td>年龄</td>
 </tr>
<"<" rel="external nofollow" >上一页</a>&nbsp;&nbsp;<a href="<" rel="external nofollow" >下一页</a>
</body>
</html>

注:当一个文件中有php和html两种时,php文件必须有结束标记

附:php通用分页类与用法:

Page.class.php文件:

<"'.$this->href.'" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >首页</a>] </span>';
    //如果当前页不是第一页就显示上页
    if($this->currPage>1){
      $_GET['page'] = $this->currPage-1;
      $pageStr.='<span>[<a href="'.$this->href.'" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >上页</a>] </span>';
    }
    foreach ($this->page_arr as $k => $v) {
      $_GET['page'] = $k;
      $pageStr.='<span>[<a href="'.$v.'" rel="external nofollow" >'.$k.'</a>] </span>';
    }
    //如果当前页小于总页数就显示下一页
    if($this->currPage<$this->countPages){
      $_GET['page'] = $this->currPage+1;
      $pageStr.='<span>[<a href="'.$this->href.'" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >下页</a>] </span>';
    }
    $_GET['page'] = $this->countPages;
    $pageStr.='<span>[<a href="'.$this->href.'" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >尾页</a>] </span>';
    return $pageStr;
  }
  /**
   * construct_Pages 生成页码数组
   * 键为页码,值为链接
   * $this->page_arr=Array(
   *         [1] => index.php"htmlcode">
<"content-type:text/html;charset=utf8");
include('Page.class.php');  //引入类
//$p=new Page(总条数,显示页数,当前页码,每页显示条数,[链接]);
//连接不设置则为当前链接
$page=isset($_GET['page']) "<pre>";
print_r($p->getPages());
//样式 共45条记录,每页显示10条,当前第1/4页 [首页] [上页] [1] [2] [3] .. [下页] [尾页]
echo $p->showPages(1);
