又一款php分页类代码

class multipage {

 var $total;
 var $perpage;
 var $pages;
 var $maxpage;
 var $offset = 9;
 var $curr_page;
 
 function init($total, $perpage, $maxpage) { //初始化页数
  $this->total;
  $this->perpage;
  $this->maxpage;
  $this->offset = 9;
 }
 
 function getpagelist() {//获取分页列表
  $result_pages = "";
  $this->pages = ceil($this->total / $this->perpage);
  
  if ($this->pages > $this->maxpage) {
   $from = $this->curr_page - $this->offset;
   if ($from     $from = 1;
   }
   $to = $from + $this->maxpage - 1;
   if ($to > $this->pages) {
    $to = $this->pages;
    if (($to - $from) maxpage) {
     $from = $from - 1;
    }
   }
  } else {
   $from = 1;
   $to = $this->pages;
  }
  
  $p = 0;
  for($i = $from; $i    $result_pages[$p] = $i;
   $p++;
  }
  
  return $result_pages;
 }
 
 function getfirst() { //获取第一页
  if ($this->curr_page > 1 && $this->pages > 1) {
   return 1;
  } else {
   return "";
  }
 }
 
 function getlast() { //取末页
  if ($this->pages > 1 && $this->curr_page pages) {
   return $this->pages;
  } else {
   return "";
  }
 }
 
 function getprev() {//上一页
  $prevpage = $this->curr_page - 1;
  if ($prevpage > 0) {
   return $prevpage;
  } else {
   $prevpage = "";
   return $prevpage;
  }
 }
 
 function getnext() {//下一页
  $nextpage = $this->curr_page + 1;
  if ($nextpage pages) {
   return $nextpage;
  } else {
   $nextpage = "";
   return $nextpage;
  }
 }
 
 function gettotal() {//共多少页
  if ($this->pages > 0) {
   return $this->pages;
  } else {
   return 1;
  }
 }
 
}

//分页类的使用方法

$page = new multipage();
$page->gettotal(); //总页娄
$page->getnext();//下一页
