简单好用的PHP分页类

本文为大家分享了两段PHP分页类，很实用，供大家参考，具体内容如下

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;
    $_pagelist .= ' '.$_page.' ';
   }
   $_pagelist .= ' '.$this->page.' ';
   for ($i=1;$i<=$this->bothnum;$i++) {
    $_page = $this->page+$i;
    if ($_page > $this->pagenum) break;
    $_pagelist .= ' '.$_page.' ';
   }
   return $_pagelist;
  }
 
  //首页
  private function first() {
   if ($this->page > $this->bothnum+1) {
    return ' 1 ...';
   }
  }
 
  //上一页
  private function prev() {
   if ($this->page == 1) {
    return '上一页';
   }
   return ' 上一页 ';
  }
 
  //下一页
  private function next() {
   if ($this->page == $this->pagenum) {
    return '下一页';
   }
   return ' 下一页 ';
  }
 
  //尾页
  private function last() {
   if ($this->pagenum - $this->page > $this->bothnum) {
    return ' ...'.$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：

使用说明：

第二个分页类：

 2)
    {
      $url = self::url(1);
      return "
首页
";
    }
  }
 
  public static function previous()
  {
    if (self::$page > 1)
    {
      $url = self::url(self::$page - 1);
      return "
上一页
";
    }
  }
 
  public static function number()
  {
    $str = '';
    $f = self::$number % 2 ? (self::$number - 1) / 2 : self::$number / 2;
    $s = self::$page - $f;
    $e = self::$page + $f;
 
    if (self::$page < ($f + 1))
    {
      $s = 1;
      $e = self::$number;
      $e = $e > self::$max ? self::$max : $e;
    }
 
    if (self::$page > (self::$max - $f))
    {
      $s = self::$max - self::$number;
      $s = $s < 1 ? 1 : $s;
      $e = self::$max;
    }
 
    for ($i=$s; $i<=$e; $i++)
    {
      $url = self::url($i);
      if ($i == self::$page)
        $str .= "
{$i}
";
      else
        $str .= "
{$i}
";
    }
    return $str;
  }
 
  public static function next()
  {
    if (self::$page < self::$max)
    {
      $url = self::url(self::$page + 1);
      return "
下一页
";
    }
  }
 
  public static function end()
  {
    if ((self::$max - self::$page) > 1)
    {
      $url = self::url(self::$max);
      return "
末页
";
    }
  }
 
  public static function url($page)
  {
    return str_replace('{page}', $page, self::$url);
  }
}
