PHP uses Redis for back-to-Queue Service

 Redis = $ redis; $ this-> key = $ key;} public function pop () {return $ this-> redis-> lPop ($ this-> key ); // left-side output} public function push ($ task) {return $ this-> redis-> rPush ($ this-> key, $ task); // right-side inbound }}

One feature of the queue is FIFO. Obviously, the first generated task needs to be processed first. redis List can ensure this.
