Message Queue MSMQ instance-PHP source code

Message Queue (MSMQ) instance message queue: a container that stores messages during message transmission. MSMQ is Microsoft's message processing technology and runs on a Microsoft Windows operating system. It is divided into user queue and system queue. User queues are divided into dedicated queues: they are not released across the network and are only available on the local computer where they reside. A dedicated queue can only be accessed by user programs that know the full path name or tag of the queue.
For message queue installation, you can choose Control Panel> add/delete Programs> add/delete Windows components.

Select "message queue" and click "details ".

If you are running Windows Server 2003, select "application Server" to access message queue.

Make sure that all options, including "msmq http support", are selected on the details page.

Click OK to exit the details page, and then click next ". Complete the installation.

　　

Here we use instances to describe how to create a queue, send messages, and receive messages.

Create a queue:
Create a local queue: @ ". \ private $ \ queue name"
Create a remote queue: @ "FormatName: DIRECT = TCP: remote machine IP \ private $ \ queue name"

Instantiate a Message Queue

/////////Is it a local machine?Public MSMQManager (bool isLocalComputer) {if (isLocalComputer) {_ path = @ ". \ private $ \" + (ConfigurationManager. deleetmanager ["MSMQName"]? "CSMSMQ");} else {_ path = @ "FormatName: DIRECT = TCP: 192.168.1.125 \ private $ \" + (ConfigurationManager. deleettings ["MSMQName"]? "CSMSMQ");} _ msmq = new MessageQueue (_ path );}

Create a queue

////// Create a queue //////Enable transaction?///
 Public bool Create (bool transactional) {if (MessageQueue. Exists (@ ". \ private $ \" + (ConfigurationManager. deleettings ["MSMQName"]? "CSMSMQ") {return true;} else {if (MessageQueue. Create (@ ". \ private $ \" + (ConfigurationManager. etettings ["MSMQName"]? "CSMSMQ"), transactional )! = Null) {return true;} else {return false ;}}}

Send Message Queue

////// Send a message queue //////Message Queue entity///
 Public void Send (MSMQIndex msmqIndex) {_ msmq. Send (new Message (msmqIndex, new BinaryMessageFormatter ()));}

Receive message queue, delete queue

////// Receive message queue, delete queue //////
 Public MSMQIndex ReceiveAndRemove () {MSMQIndex msmqIndex = null; _ msmq. formatter = new BinaryMessageFormatter (); Message msg = null; try {msg = _ msmq. receive (new TimeSpan (0, 0, 1);} catch (Exception ex) {Console. writeLine (ex. message);} if (msg! = Null) {msmqIndex = msg. Body as MSMQIndex;} return msmqIndex ;}

The above code roughly describes how to create, send, and receive a message queue. The following describes all the code of the message queue manager. A demo is provided in the attachment. after you have installed the message queue, the DEMO can run normally, and it is helpful to those who need it.

This DEMO only introduces and uses message queues, and some concepts of message queues are not described. for example:

Message Queue creation method: Path, format name, and tag;

Message Queue receiving method: synchronous and asynchronous;

Message Queue serialization: character, XML, binary;

And whether to use transactions.
