如我们指定分页时,每页20篇。某子频道列表内文章经数据库查询为45条,则,首先我们通过查询得到如下参数:1,总页数;2,每页篇数。第二步,for ($i = 0; $i
  Code:  
  $fp          = fopen ("temp.html","r");
  $content  = fread ($fp,filesize ("temp.html"));
  $onepage  = ''20'';
  $sql          = "select id from article where channel=''$channelid''";
  $query      = mysql_query ($sql);
  $num        = mysql_num_rows ($query);
  $allpages   = ceil ($num / $onepage);
  for ($i = 0;$i      if ($i == 0){
        $indexpath = "index.html";
      } else {
        $indexpath = "index_".$i."html";
      }
     $start = $i * $onepage;
     $list    = '''';
     $sql_for_page = "select name,filename,title from article where channel=''$channelid'' limit $start,$onepage";
     $query_for_page = mysql_query ($sql_for_page);
     while ($result = $query_for_page){
        $list .= ''''.$title.''
'';
      }
    
     $content = str_replace ("{ articletable }",$list,$content);
     if (is_file ($indexpath)){
        @unlink ($indexpath); //若文件已存在,则删除
      }
     $handle    = fopen ($indexpath,"w"); //打开文件指针,创建文件
     /*
    检查文件是否被创建且可写
     */
     if (!is_writable ($indexpath)){
        echo "文件:".$indexpath."不可写,请检查其属性后重试!"; //修改为echo
      }
     if (!fwrite ($handle,$content)){  //将信息写入文件
        echo "生成文件".$indexpath."失败!"; //修改为echo
      }
     fclose ($handle); //关闭指针
  }
  fclose ($fp);
  die ("生成分页文件完成,如生成不完全,请检查文件权限系统后重新生成!");
?>  
  大致思路如此,其中如其它数据生成,数据输入输出检查,分页内容指向等可酌情在页面中加入。
  在实际文章系统处理过程当中,还有许多问题有待考虑,与动态页面不同之处,需注意的地方还有很多。但大致思路即是如此,其它方面可举一反三而得。
