這篇文章跟大家介紹的內容是關於thinkphp如何實現分組獲取滿足條件的數據,有一定的參考價值,有需要的朋友可以參考一下,希望對你有所幫助。
thinkphp分組取得符合條件的資料:
<?php //分组获取满足条件的一亩地ID $cinema_id = $this->getCunIdById($change_num); //cun_use表(cun_id分组),获取要换取的大于该cun_use剩余的数量 private function getCunIdById($change_num){ $f="cu.cun_id,count(cu.id) as receive_num"; $c=" and cu.cun_id != 0 and cu.cun_id= 2 and cu.user_id = 0 and cu.use_status = 0"; $groupCunUse = $this->getExchageByCunId($c,$f); foreach ($groupCunUse as $gk => $gv) { if($gv['receive_num'] >= $change_num){ $cinema_id =$gv['cinema_id']; break; } } return $cinema_id; } //cun_use表(cun_id分组),获取要换取的大于该cun_use剩余的数量 public function getExchageByCunId($condition,$field){ if (!$condition) { return false; }else{ return M('cun_use')->table('cun_use cu,cun_piao cp')->where(' cu.cun_id = cp.cun_id'.$condition)->field($field)->group('tu.cun_id')->select(); } }
