PHP execution timing task queue using Redis

Redis categories:

<?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对象
         * @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");

                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 common queue Method:

//队列第一个 =>出列
$Redis->lPop($key);
//入到 =>队列最后
$Redis->rPush($key);


//队列最后一个 =>出列
$Redis->rPop($key);
//入到 =>队列第一个
$Redis->rPop($key);

//返回整个列表的值，不出列
$redis->lRange($key,0,-1);
