这篇文章主要介绍了PHP实现的分页类定义与用法,结合具体实例形式分析了php封装的分页类常用操作及具体使用技巧,需要的朋友可以参考下
本文实例讲述了PHP实现的分页类定义与用法。分享给大家供大家参考,具体如下:
total = $_total ? $_total : 1;
$this->pagesize = $_pagesize;
$this->pagenum = ceil($this->total / $this->pagesize);
$this->page = $this->setPage();
$this->limit = "LIMIT ".($this->page-1)*$this->pagesize.",$this->pagesize";
$this->url = $this->setUrl();
$this->bothnum = 2;
}
//拦截器
private function __get($_key) {
return $this->$_key;
}
//获取当前页码
private function setPage() {
if (!empty($_GET['page'])) {
if ($_GET['page'] > 0) {
if ($_GET['page'] > $this->pagenum) {
return $this->pagenum;
} else {
return $_GET['page'];
}
} else {
return 1;
}
} else {
return 1;
}
}
//获取地址
private function setUrl() {
$_url = $_SERVER["REQUEST_URI"];
$_par = parse_url($_url);
if (isset($_par['query'])) {
parse_str($_par['query'],$_query);
unset($_query['page']);
$_url = $_par['path'].'?'.http_build_query($_query);
}
return $_url;
} //数字目录
private function pageList() {
for ($i=$this->bothnum;$i>=1;$i--) {
$_page = $this->page-$i;
if ($_page < 1) continue;
$_pagelist .= ' url.'&page='.$_page.'" rel="external nofollow" rel="external nofollow" >'.$_page.' ';
}
$_pagelist .= ' page.' ';
for ($i=1;$i<=$this->bothnum;$i++) {
$_page = $this->page+$i;
if ($_page > $this->pagenum) break;
$_pagelist .= ' url.'&page='.$_page.'" rel="external nofollow" rel="external nofollow" >'.$_page.' ';
}
return $_pagelist;
}
//首页
private function first() {
if ($this->page > $this->bothnum+1) {
return ' url.'" rel="external nofollow" >1 ...';
}
}
//上一页
private function prev() {
if ($this->page == 1) {
return '';
}
return ' url.'&page='.($this->page-1).'" rel="external nofollow" >上一页 ';
}
//下一页
private function next() {
if ($this->page == $this->pagenum) {
return '';
}
return ' url.'&page='.($this->page+1).'" rel="external nofollow" >下一页 ';
}
//尾页
private function last() {
if ($this->pagenum - $this->page > $this->bothnum) {
return ' ...url.'&page='.$this->pagenum.'" rel="external nofollow" >'.$this->pagenum.' ';
}
}
//分页信息
public function showpage() {
$_page .= $this->first();
$_page .= $this->pageList();
$_page .= $this->last();
$_page .= $this->prev();
$_page .= $this->next();
return $_page;
}
}
?>
分页样式如下图所示:
