本文实例为大家分享了php分页类的具体代码，供大家参考，具体内容如下
allUrl());
class Page{
// 每页显示的个数
protected $number;
// 一共有多少数据
protected $totalCount;
// 当前页
protected $page;
// url
protected $url;
public function __construct($number,$totalCount){
$this->number= $number;
$this->totalCount = $totalCount;
//得到总页数
$this->totalPage = $this->getTotalPage();
//得到当前页数
$this->page = $this->getPage();
//得到URL
$this->url = $this->getUrl();
echo $this->url;
}
/*得到总页数并向上取整*/
protected function getTotalPage(){
return ceil($this->totalCount/$this->number);
}
/**/
protected function getPage(){
if (empty($_GET['page'])){
$page=1;
}elseif ($_GET['page'] > $this->totalPage){
$page = $this->totalPage;
}elseif ($_GET["page"]url, '?')){
$url = $this->url.'&'.$str;
}else{
$url = $this->url.'?'.$str;
}
return $url;
}
/*所有的url*/
public function allUrl(){
return [
'first' => $this->first(),
'next' => $this->next(),
'prev'=> $this->prev(),
'end'=> $this->end(),
];
}
/*首页*/
public function first(){
return $this->setUrl('page=1');
}
/*下一页*/
public function next(){
//根据当前page得带下一页的页码
if ($this->page+1 > $this->totalPage) {
$page = $this->totalPage;
}else{
$page = $this->page+1;
}

/*上一页*/
public function prev(){

/*尾页*/

/*limit 0,5*/
