本文实例讲述了PHP封装的完整分页类。分享给大家供大家参考，具体如下：
rush:PHP;">
total = $_total ? $_total :1 ; //总条数
$this->pagesize = $_pagesize; //每页显示多少条
$this->page = $page; //当前页码
$this->pagenum = ceil($this->total / $this->pagesize); //总页码
$this->limit = "limit ".($this->page-1)*$this->pagesize.",".$this->pagesize; //分页语句
$this->url = $this->setUrl(); //地址
}
//分页语句
public function limit(){
return $this->limit;
}
//当前的URL地址
public function setUrl(){
$server = $_SERVER['REQUEST_URI'];
$im = explode('/',$server);
if(empty($_SERVER['PATH_INFO'])){
$array = array_splice($im,2,array('2'=>'index.PHP'));
}
$controller = $im[3];
$action = $im[4];
if(empty($_SERVER['PATH_INFO'])){
$servers = "http://".$_SERVER['HTTP_HOST']."/".$im[1]."/".$controller."/".$action."/";
}else{
$servers = "http://".$_SERVER['HTTP_HOST'].$_SERVER['SCRIPT_NAME']."/".$controller."/".$action."/";
}
return $servers;
//return $im;
}
//首页
public function first(){
//return $this->page;
if($this->page > 1){
return "首页";
}
}
//上一页
public function prev(){
if($this->page==1){
$page = 1;
}else{
$page = $this->page-1;
}
if($this->page > 1){
return "上一页";
}else{
return "上一页";
}
}
//下一页
public function next(){
$page = $this->page+1;
if($this->page < $this->pagenum){
if(empty($this->page)){
$pages = $this->page+2;
return "下一页";
}else{
return "下一页";
}
}else{
return "下一页";
}
}
//尾页
public function last(){
if($this->page < $this->pagenum){
return "尾页";
}
}
//分页
public function showpage(){
$page_ = "";
$page_ .= $this->first();
$page_ .= " ".$this->prev();
$page_ .= " ".$this->next();
$page_ .= " ".$this->last();
return $page_;
}
}
