本文实例讲述了PHP封装的分页类与简单用法。分享给大家供大家参考,具体如下:
分页类的封装如下:
page.php
<?php //showPage(页号,总页数,分隔符) function showPage($page,$totalPage,$sep=" "){ $url = $_SERVER ['PHP_SELF']; //获取当前路径 $index = ($page == 1) ? "首页" : "<a href='{$url}?page=1'>首页</a>"; $last = ($page == $totalPage) ? "尾页" : "<a href='{$url}?page={$totalPage}'>尾页</a>"; $prevPage=($page>=1)?$page-1:1; $nextPage=($page>=$totalPage)?$totalPage:$page+1; $prev = ($page == 1) ? "上一页" : "<a href='{$url}?page={$prevPage}'>上一页</a>"; $next = ($page == $totalPage) ? "下一页" : "<a href='{$url}?page={$nextPage}'>下一页</a>"; $str = "总共{$totalPage}页/当前是第{$page}页"; $p=""; for($i = 1; $i <= $totalPage; $i ++) { //当前页无连接 if ($page == $i) { $p .= "[{$i}]"; } else { $p .= "<a href='{$url}?page={$i}'>[{$i}]</a>"; } } $pageStr=$str.$sep . $index .$sep. $prev.$sep . $p.$sep . $next.$sep . $last; return $pageStr; //返回分页字符串 }
一个调用分页类的例子
userlist.php
<?php include "../mysql.php"; include "../page.php"; //连接数据库 $conn=new Mysql(); // $pageSize=2; //每页显示的记录数 $sql="select * from user;"; $totalRows=$conn->getResultNum($sql); //总记录数 $totalPage=ceil($totalRows/$pageSize); //总页数 $page=isset($_REQUEST['page'])?(int)$_REQUEST['page']:1;//当前页数 if($page<1||$page==null||!is_numeric($page)){ $page=1; } if($page>=$totalPage)$page=$totalPage; $offset=($page-1)*$pageSize; $sql="select * from user limit {$offset},{$pageSize}"; $result=$conn->sql($sql); echo "<table style='text-align: center'>"; echo "<tr><td>用户名</td><td>密码</td><td>性别</td><td>邮箱</td></tr>"; foreach ($result as $k=>$v) { echo "<tr><td>{$v['name']}</td>"; echo "<td>"."{$v['password']}"."</td>"; echo "<td>{$v['sex']}</td>"; echo "<td>{$v['email']}</td></tr>"; } echo "</table>"; echo showPage($page,$totalPage); //输出页码链接 echo"<hr/>"; //关闭数据库 $conn->close();
运行结果:
希望本文所述对大家PHP程序设计有所帮助。
