_php tutorial on Memcache-based queue implementation code written in PHP

PHP Class Code:
Copy CodeThe code is as follows:
Class mq{
public static $client;
private static $m _real;
private static $m _front;
private static $m _data = Array ();
Const QUEUE_MAX_NUM = 100000000;

}
}

}

}
}
Define (' Flush_mq ', 0);//clean all DATA
Define (' Is_add ', 0);//set DATA
$mobj = MQ::SETUPMQ (' 127.0.0.1 ', ' 11211 ');
if (FLUSH_MQ) {
Mq::mflush ($mobj);
} else {
if (Is_add) {
Mq::add (' User_sync ', ' 1test ');
Mq::add (' User_sync ', ' 2test ');
Mq::add (' User_sync ', ' 3test ');
Mq::add (' User_sync ', ' 4test ');

Mq::add (' User_sync ', ' 6test ');
} else {
Mq::get (' User_sync ', 10);
}
}
MQ::D ebug ();
?>
 
How to use
Copy CodeThe code is as follows:
MQ::SETUPMQ (' 127.0.0.1 ', ' 11211 ');//Connection
Mq::add ($key, $value);//Add data to the queue
Mq::add ($key, $value);//Add data to the queue
Mq::add ($key, $value);//Add data to the queue
Mq::add ($key, $value);//Add data to the queue
Mq::add ($key, $value);//Add data to the queue
Mq::add ($key, $value);//Add data to the queue
Mq:get ($key, 10);//Remove a certain amount of data
