Problems in implementation of Message Queuing feed program

Because of the project needs, build a lot of Message Queuing also queued processing tasks, each corresponding queue also has a feed program to feed messages

At first, it was easy to do this:

         while (true) {            $msg$query, Bpop ();             // message handlers        }

In this way the feed program will never quit at first, but there is a problem, once the message handler changes, if the process is not restarted after the manual kill process, the changes will not be loaded.

Another: It is said that the PHP process runs too long to generate garbage is difficult to reclaim, need to terminate the process to reclaim process garbage.

So I say the feed program is changed to the following way:

        Set_time_limit(0 ); $startTime= Time (); $maxDealNum= 1000;//Maximum processing times        $maxLifeTime= 12 * 3600;//maximum life cycle duration        $dealedNum= 0;  while(true ) {            $this->load->model (' item/category_frequently ')bdealmsg (); $dealedNum++; //The program exits when the maximum number of processing times or processing time is exceeded to clean up the memory garbage in a way that daemon restarts            if($dealedNum>$maxDealNum|| ( Time() -$startTime) >$maxLifeTime) {                return; }        }

After each processing of a message count, as well as record feed program start execution time, if 2 people are more than a certain threshold to let the program exit, so you can avoid a single long time hungry or perform frequent scenarios will not exit the process. When the message handler changes, it can be reloaded within the expected time
