对于这个问题,大家可以find_in_set函数,可以很好的解决。
$sql="select * from ".tablename('weh5app_bobing_records')." where weid=".$_W['uniacid'];
		$sql_count="select count(*) from ".tablename('weh5app_bobing_records')." where weid={$_W['uniacid']}";
		if(!empty($openid_str))
		{
			//$sql.=" and '".$openid_str."' like concat('%', openid, '%')";
			//$sql_count=" and '".$openid_str."' like concat('%', openid, '%')";
			$sql.=" and find_in_set(openid,'".$openid_str."')";
			$sql_count.=" and find_in_set(openid,'".$openid_str."')";
		}正文完
