php自定义分页类
<?php class page{ public $page; public $pagenum; public $pagesize; public function __construct($count,$pagesize){ $this->pagenum=ceil($count/$pagesize); $this->pagesize=$pagesize; $this->page=(isset($_GET['p'])&&$_GET['p']>0)?intval($_GET['p']):1;//首次调用类么?是的话就让P值为1 } public function getUrl(){ $url =basename($_SERVER['PHP_SELF']). '?'.http_build_query($_GET); $url=preg_replace('/[?,&]p=(\w)+/','',$url); $url.=(strpos($url,"?")===false)?'?':'&'; return $url;//这里返回的是没有P参数的URL } public function getPage(){ $url=$this->getUrl(); $start=$this->page-5; $start=$start>0?$start:1; $end=$start+9; $end=$end<$this->pagenum?$end:$this->pagenum; $pagestr=''; if($this->page>5){ $pagestr="<a href=".$url."p=1".">first page</a>"; } if($this->page!=1){ $pagestr="<a href=".$url."p=".($this->page-1).">pre </a>"; } for($i=$start;$i<=$end;$i++){ $pagestr.="<a href=".$url."p=".$i."> ".$i." </a>"; } if($this->page!=$this->pagenum){ $pagestr.="<a href=".$url."p=".($this->page+1).">next </a>"; } if($this->page+5<$this->pagenum){ $pagestr.="<a href=".$url."p=".$this->pagenum.">last_page</a>"; } return $pagestr; } } $page=new page(1000,7); $str=$page->getPage(); echo $str; ?>
