是我最近写论坛的时候，把以前的分页函数包装了一下，例 在下页

/////////////////分页函数/////////////////////////////
class page_num
{
  var $pagestat = 0;
  var $pagemenu = '';
  var $tem='';
 function add_var($arr) {
   
  foreach ($arr as $k=>$v){
   if($v)
   $this->tem .= "$k=$v&";
   }
  }
 function page_menu($total_file,$recnum=20) {
        global $_GET,$PHP_SELF;
        if (isset($_GET["p"])) $p = $_GET["p"];
 if ($total_file % $recnum ==0)
     $totalnum = intval (($total_file) / $recnum); //如果此处错误，没传值过来，看看 $_GEI 和 $_POST
 else
           $totalnum = intval (($total_file) / $recnum)+1;
        $listnum = 10;
        $pagenum = $p;
        if(!$p){$pagenum = 1; $p = 1;}
 $this->pagestat=($p-1)*$recnum;
        if($p > $listnum) {
                if ($p == 1) {
                      $fenye.= "n";
                }
                else {
                        $PrevPage = $p-1;
                       $fenye.= "<a href=$PHP_SELF?".$this->tem."p=1 title=首页>[1]</a>n";
                }
        }
        $term = $listnum;$f = 1;$l = $term;while ($f <= $totalnum) {
        if (($f <= $p) && ($p <= $l)) {
                $prevp = $f - 1;
                if ($prevp > 0) {
                       $fenye.= "<a href=$PHP_SELF?".$this->tem."p=$prevp title="前 $listnum页">[Prev]</a>-";
                }
                else {
               $fenye.= "n";
                }
                if ($l <= $totalnum) {
                        for ($page = $f; $page <= $l; $page++) {

                                }
                        }
                }
                $nextp = $l + 1;
                if ($nextp <= $totalnum) {
