<?php 
//(ps:推荐使用laypage整站式跳转来渲染分页按钮样式比较舒服http://laypage.layui.com/,还可以开启内置样式和跳页等功能很不错哦~)
//require_once ‘../include.php‘;
//$sql="select * from imooc_admin";
//$totalRows=getResultNum($sql);
////echo $totalRows;
//$pageSize=2;
////得到总页码数
//$totalPage=ceil($totalRows/$pageSize);
//$page=$_REQUEST[‘page‘]?(int)$_REQUEST[‘page‘]:1;
//if($page<1||$page==null||!is_numeric($page)){
//    $page=1;
//}
//if($page>=$totalPage)$page=$totalPage;
//$offset=($page-1)*$pageSize;
//$sql="select * from imooc_admin limit {$offset},{$pageSize}";
////echo $sql;
//$rows=fetchAll($sql);
////print_r($rows);
//foreach($rows as $row){
//    echo "编号:".$row[‘id‘],"<br/>";
//    echo "管理员的名称:".$row[‘username‘],"<hr/>";
//}
//echo showPage($page,$totalPage);
//echo "<hr/>";
//echo showPage($page,$totalPage,"cid=5&pid=6");
function showPage($page,$totalPage,$where=null,$sep="&nbsp;"){
    $where=($where==null)?null:"&".$where;
    $url = $_SERVER [‘PHP_SELF‘];
    $index = ($page == 1) ? "首页" : "<a href=‘{$url}?page=1{$where}‘>首页</a>";
    $last = ($page == $totalPage) ? "尾页" : "<a href=‘{$url}?page={$totalPage}{$where}‘>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}{$where}‘>上一页</a>";
    $next = ($page == $totalPage) ? "下一页" : "<a href=‘{$url}?page={$nextPage}{$where}‘>下一页</a>";
    $str = "总共{$totalPage}页/当前是第{$page}页";
    for($i = 1; $i <= $totalPage; $i ++) {
        //当前页无连接
        if ($page == $i) {
