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:
= $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);
?>
document
| 学号 | 姓名 | 性别 | 年龄 |
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:
count=$count;
$this->showPages=$showPages;
$this->currPage=$currPage;
$this->subPages=$subPages;
//如果链接没有设置则获取当前连接
if(empty($href)){
$this->href=htmlentities($_SERVER['PHP_SELF']);
}else{
$this->href=$href;
}
$this->construct_Pages();
}
public function getPages(){
return $this->page_arr;
}
public function showPages($style=1){
$func='pageStyle'.$style;
return $this->$func();
}
protected function pageStyle1(){
$pageStr='共'.$this->count.'条记录,每页显示'.$this->subPages.'条';
$pageStr.='当前第'.$this->currPage.'/'.$this->countPages.'页 ';
$_GET['page'] = 1;
$pageStr.='[href.'?'.http_build_query($_GET).'" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >首页] ';
//如果当前页不是第一页就显示上页
if($this->currPage>1){
$_GET['page'] = $this->currPage-1;
$pageStr.='[href.'?'.http_build_query($_GET).'" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >上页] ';
}
foreach ($this->page_arr as $k => $v) {
$_GET['page'] = $k;
$pageStr.='['.$k.'] ';
}
//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;
$pageStr.='[href.'?'.http_build_query($_GET).'" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >下页] ';
}
$_GET['page'] = $this->countPages;
$pageStr.='[href.'?'.http_build_query($_GET).'" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >尾页] ';
return $pageStr;
}
protected function construct_Pages(){
//计算总页数
$this->countPages=ceil($this->count/$this->subPages);
//根据当前页计算前后页数
$leftPage_num=floor($this->showPages/2);
$rightPage_num=$this->showPages-$leftPage_num;
//左边显示数为当前页减左边该显示的数 例如总显示7页 当前页是5 左边最小为5-3 右边为5+3
$left=$this->currPage-$leftPage_num;
$left=max($left,1); //左边最小不能小于1
$right=$left+$this->showPages-1; //左边加显示页数减1就是右边显示数
$right=min($right,$this->countPages); //右边最大不能大于总页数
$left=max($right-$this->showPages+1,1); //确定右边再计算左边,必须二次计算
for ($i=$left; $i <= $right; $i++) {
$_GET['page'] = $i;
$this->page_arr[$i]=$this->href.'?'.http_build_query($_GET);
}
}
}
?>
用法示例demo.php:
"; 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);
