The example in this article describes the PHP Message Queuing usage. Share to everyone for your reference, as follows:

This message queue is used under Linux for process communication

#根据路径和后缀创建一个id $key = Ftok (__dir__, ' R '); #获取队列中的消息 $q = Msg_get_queue ($key); #删除队列msg_remove_queue ($q); #获取队列的状态信息 $ Status = Msg_stat_queue ($q);p Rint_r ($status), echo "\ n", for ($i =0; $i <100; $i + +) {/** * Add message to queue * Resource $queue, int $msgtype, mixed $message [, bool $serialize = True [, bool $blocking = true [, int & $errorcode]] * $msgtype: Type of message * $message: Specific data * $serialize: whether to serialize * $blocking: Whether blocking, when the queue is full, will block, set to non-blocking will produce a msg_eagain error message * * * $FL  AG = Msg_send ($q, 111, Array (' A ' =>1), True, false, $errorcode); Var_dump ($errorcode);}  /** Receive Message resource $queue, int $desiredmsgtype, int & $msgtype, int $maxsize, mixed & $message [, BOOL $unserialize = True [, int $flags = 0 [, int & $errorcode]] $desiredmsgtype: 0 means return data from the front of the queue, bigger 0: Specific queue $maxsize: Data max, get message If this value is faulted $msgtype: the exact type of the message, because $desiredmsgtype can specify no type, that is, 0$flags:msg_ipc_nowait if the queue is empty directly (without blocking), msg_except Msg_ NOERROR See manual */$data = msg_receive ($q, 0, $type, $msg), Var_dump ($data); EchO "\ n"; var_dump ($type); echo "\ n"; var_dump ($msg); echo "\ n"; 

Queue status information: specific reference manuals

Array ([Msg_perm.uid] = 1015[msg_perm.gid] = 100[msg_perm.mode] = 438[msg_stime] = 0[msg_rtime] = 0[ Msg_ctime] = 1411830331[msg_qnum] [0[msg_qbytes] = 65536[msg_lspid] = 0[msg_lrpid] + 0)
