一款PHP自动竞拍出价程序

时间：2015-01-23 来源：西部数据作者：西部数据

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,都是一些人性化的功能,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phpfensi.com

                $seconds=explode(',',$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;

}
