PHP uses ActiveMQ case analysis (with code)

This time I will bring you a case analysis of PHP using ActiveMQ (with code). What are the precautions for PHP using ActiveMQ? The following is a practical case, let's take a look.

Use Point To PointModel

Features of point-to-point model:

• Only one consumer can receive the message

• Cannot be consumed repeatedly

producer producer.php code：

<?php
try {
  // 1.建立连接
  $stomp = new Stomp(&#39;tcp://47.52.119.21:61613&#39;);
  // 2.实例化类
  $obj = new Stdclass();
  // 3.获取数据
  for($i=0; $i<3; $i++){
    $obj->username = 'test';
    $obj->password = '123456';
    $queneName   = "/queue/userReg";
    // 4.发送一个注册消息到队列
    $stomp->send($queneName, json_encode($obj));
  }
} catch (StompException $e) {
  die('Connection failed: ' . $e->getMessage());
}

consumer1consumer1 .php code:

<?php
$stomp = new Stomp(&#39;tcp://localhost:61613&#39;);
$stomp->subscribe('/queue/userReg');
while (true) {
  //判断是否有读取的信息
  if ($stomp->hasFrame()) {
    $frame = $stomp->readFrame();
    $data = json_decode($frame->body, true);
    var_dump($data);
    $stomp->ack($frame);
  }
}

Consumer2consumer2.php code:

<?php
$stomp = new Stomp(&#39;tcp://localhost:61613&#39;);
$stomp->subscribe('/queue/userReg');
while (true) {
  //判断是否有读取的信息
  if ($stomp->hasFrame()) {
    $frame = $stomp->readFrame();
    $data = json_decode($frame->body, true);
    var_dump($data);
    $stomp->ack($frame);
  }
}

The execution result is as follows:

##Use publish/subscribe ( Publish Subscribe) model

Publish/subscribe model features:

Multiple consumers can receive messages

Can be consumed repeatedly
Producer producer.php code:

<?php
try {
  // 1.建立连接
  $stomp = new Stomp(&#39;tcp://47.52.119.21:61613&#39;);
  // 2.实例化类
  $obj = new Stdclass();
  // 3.获取数据
  for($i = 0; $i < 3; $i++){
    $obj->username = 'test';
    $obj->password = '123456';
    $queneName   = "/topic/userReg";
    // 4.发送一个注册消息到队列
    $stomp->send($queneName, json_encode($obj));
  }
} catch (StompException $e) {
  die('Connection failed: ' . $e->getMessage());
}

Consumer 1consumer1.php code:

<?php
$stomp = new Stomp(&#39;tcp://localhost:61613&#39;);
$stomp->subscribe('/topic/userReg');
while (true) {
  //判断是否有读取的信息
  if ($stomp->hasFrame()) {
    $frame = $stomp->readFrame();
    $data = json_decode($frame->body, true);
    var_dump($data);
    $stomp->ack($frame);
  }
}

Consumer 2consumer2.php code:

?php
$stomp = new Stomp('tcp://localhost:61613');
$stomp->subscribe('/topic/userReg');
while (true) {
  //判断是否有读取的信息
  if ($stomp->hasFrame()) {
    $frame = $stomp->readFrame();
    $data = json_decode($frame->body, true);
    var_dump($data);
    $stomp->ack($frame);
  }
}

The execution result is as follows:
