功能：用户提交自己的信息后，保存在数据库中，程序每一次读取当前结果时都要判断一次，如用户可设置几秒钟时参加竞拍，竞拍多少次，并且可以设置前面有多少人竞拍后我才参加，比较人性化的功能，实例代码如下:

function auto($second,$gid,$shutuid) 
{ 
  global $table_prefix; 
  //取出此商品已经竞拍次数 
  $maxnumber=0; 
  $unumber=array(); 
  $query=mysql_query("select id,uid from `".$table_prefix."buylog` where gid=".$gid); 
  while($rows=mysql_fetch_assoc($query)) 
  { 
      $maxnumber++; 
      if(isset($unumber[$rows['uid']])) 
      { 
        $unumber[$rows['uid']]++; 
      } 
      else 
      { 
        $unumber[$rows['uid']]=0; 
      } 
  } 
  //取出自动竞拍的会员 
  $sql="select uid,username,number,second,maxnumber,gid,ip from `".$table_prefix."autobuy` where gid=".$gid; 
  $query=mysql_query($sql); 
  $allow=array(); 
  $shutuid=explode(',',$shutuid); 
  while($rows=mysql_fetch_assoc($query)) 
  { //开源代码 Mou.Pw 
      $seconds=explode(',',$rows['second']); 
      $unumber[$rows['uid']]=isset($unumber[$rows['uid']])?$unumber[$rows['uid']]:0; 
      if(in_array($second,$seconds) && !in_array($rows['uid'],$shutuid) && $rows['maxnumber']<=$maxnumber && $rows['number']>$unumber[$rows['uid']]) //包含时刻,并且不在黑名单,符合此会员竞拍次数设置 
      { 
        $allow[]=$rows['uid']; 
      } 
  } 
  $allowuser=array(); 
  if($allow) 
  { 
      $query=mysql_query('select uid,username,money,ip from `'.$table_prefix.'user` where uid in ('.implode(',',$allow).')'); 
      while($rows=mysql_fetch_assoc($query)) 
      { 
        $allowuser[]=$rows; 
      } 
  } 
  unset($allow,$sql,$number,$maxnumber,$shutuid,$query,$u); 
  return $allowuser;
