PHP利用Redis行列执行按时任务实例讲授

<?php namespace Utils; use Phalcon\Config\Adapter\Ini as ConfigIni; class Redis{ private static $redis1; private static $session; /** * 获取一个单例的redis工具 * @param string $name * @return \Redis */ public static function getObj($name='redis1') { try{ if(!empty(self::$$name)){ return self::$$name; } $config = new ConfigIni(APP_PATH."/config".ENV."/redis.ini"); self::$$name = new \Redis(); self::$$name->connect($config[$name]['host'], $config[$name]['port'],2); if(isset($config[$name]['password']) && !empty($config[$name]['password'])){ self::$$name->auth($config[$name]['password']); } self::$$name->select($config[$name]['database']); }catch (\Exception $exception){ self::$$name = false; } return self::$$name; } };

按时任务：

/** * 订单任务 */ public function orderAction() { error_reporting(E_ALL & ~E_NOTICE); $redis = Redis::getObj(); //获取数据库毗连实例 $db = $this->getDI()->getShared('db'); while (true) { print_r(' -start- '); $order_status = 1; file_put_contents(APP_PATH . "/../domain_order.log", time()); try { //防备长时间无任务导致MySQL超时 $db->query("select 1"); //出列 $order_info = $redis->lPop('order'); if (!$order_info) {//行列为空时暂停 echo ' -empty- '; sleep(1); continue; } $order_info = json_decode($order_info, true); $model_order_info = NetUserOrder::findFirst(['order_sn = :order_sn:','bind'=>['order_sn'=>$order_domain_info_save->order_sn]]); //未付出 if($model_order_info->pay_status != 200){ echo 'no pay'; continue; } //已操纵 if ($order_domain_info_save->order_status == 3) { echo ' -Operated- '; continue; } //事务开始 $db->begin(); ## 这里执行订单流程操纵 ## $order_status = 3;//操纵乐成 //修改订单状态 $order_domain_info_save->order_status = $order_status; $order_domain_info_save->operation_time = time(); $order_domain_info_save->update(); } //提交事务 $db->commit(); printf('### succ order_id' . $order_info['id'] . ' ###'); } catch (\Exception $e) { //回滚事务 $db->rollback(); $order_status = 2;//操纵失败 $order_domain_info_save->order_status = $order_status; $order_domain_info_save->operation_time = time(); $order_domain_info_save->update(); printf(' error ' . $e->getMessage() . ' '); //异常,发送通知 Log::error($e->getMessage()); $redis->hSet('order_domain_retry', 'domain_retry_' . $order_info['id'], json_encode($order_info)); }

Redis常用行列要领：

//行列第一个 =>出列 $Redis->lPop($key); //入到 =>行列最后 $Redis->rPush($key); //行列最后一个 =>出列 $Redis->rPop($key); //入到 =>行列第一个 $Redis->rPop($key); //返回整个列表的值，不出列 $redis->lRange($key,0,-1);
