PHP ZeroMQ
What is ZeroMQ?
ZeroMQ (also known as ØMQ) is a high-performance asynchronous messaging library that provides a message queue for inter-process communication (IPC). It is designed to be lightweight, fast, and flexible, making it suitable for a wide range of applications, from simple messaging systems to complex distributed architectures.
Key Features
- Socket Abstraction: Various socket types for different messaging patterns (e.g., PUB/SUB, REQ/REP).
- Asynchronous I/O: Handle multiple connections without blocking.
- Scalability: Designed to scale from a single machine to distributed systems.
- Transport Protocols: Supports TCP, IPC, and multicast communication.
- No Dedicated Message Broker: Reduces complexity and overhead.
- Lightweight: Suitable for performance-critical applications.
Use Cases
- Microservices Communication
- Real-time Data Processing
- Distributed Systems
- Task Distribution
Example
In this example, the publisher sends messages to a specified port, and the subscriber receives those messages, illustrating the basic PUB/SUB pattern that ZeroMQ supports.
Cpanel and PHP
In CPANEL under PHP Selector under PHP Extensions select ZMQ.
server.php
// server.php
$context = new ZMQContext();
$socket = $context->getSocket(ZMQ::SOCKET_REP);
// Bind the socket to the server's shared IP address and a specific port
$socket->bind("tcp://your-ip:5555");
while (true) {
// Wait for the next request from the client
$message = $socket->recv();
echo "Received request: $message\n";
// Send a reply back to the client
$socket->send("World");
}
Start
/server.php in one tab.
client.php
// client.php
$context = new ZMQContext();
$socket = $context->getSocket(ZMQ::SOCKET_REQ);
// Connect to the server using the shared IP address
$socket->connect("tcp://your-ip:5555");
// Send a request to the server
$socket->send("Hello");
// Get the reply from the server
$message = $socket->recv();
echo "Received reply: $message\n";
Target
/client.php with your browser and you should see:
