PHP封装的完整分页类示例

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：

<?php class pageclass{  private $total;   //总记录  private $pagesize;   //每页显示多少条  private $limit;    //limit  private $page;    //当前页  private $pagenum;  //总页码  private $url;    //地址  public function __construct($_total,$_pagesize,$page){    $this->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,2,0,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 "<a href='".$this->url."page/1'>首页</a>";    }  }  //上一页  public function prev(){    if($this->page==1){      $page = 1;    }else{      $page = $this->page-1;    }    if($this->page > 1){      return "<a href='".$this->url."page/".$page."'>上一页</a>";    }else{      return "<span class='disabled'>上一页</span>";    }  }  //下一页  public function next(){    $page = $this->page+1;    if($this->page < $this->pagenum){      if(empty($this->page)){        $pages = $this->page+2;        return "<a href='".$this->url."page/".$pages."'>下一页</a>";      }else{        return "<a href='".$this->url."page/".$page."'>下一页</a>";      }    }else{      return "<span class='disabled'>下一页</span>";    }  }  //尾页  public function last(){    if($this->page < $this->pagenum){      return "<a href='".$this->url."page/".$this->pagenum."'>尾页</a>";    }  }  //分页  public function showpage(){    $page_ = "";    $page_ .= $this->first();    $page_ .= " ".$this->prev();    $page_ .= " ".$this->next();    $page_ .= " ".$this->last();    return $page_;  }}
