What best practices should be followed when implementing a system to detect database changes in PHP and trigger corresponding actions in real-time?

When implementing a system to detect database changes in PHP and trigger corresponding actions in real-time, it is recommended to use triggers in the database to capture changes and then use a messaging system like RabbitMQ or Kafka to publish these changes. On the PHP side, you can subscribe to these messages and trigger the corresponding actions based on the received data. 

// Example code snippet to subscribe to RabbitMQ messages and trigger corresponding actions

$connection = new AMQPStreamConnection('localhost', 5672, 'guest', 'guest');
$channel = $connection->channel();

$channel->queue_declare('database_changes', false, true, false, false);

echo "Waiting for database changes. To exit press CTRL+C\n";

$callback = function($msg) {
  // Perform actions based on the received database change message
  echo 'Received message: ', $msg->body, "\n";
};

$channel->basic_consume('database_changes', '', false, true, false, false, $callback);

while(count($channel->callbacks)) {
  $channel->wait();
}

$channel->close();
$connection->close();
