Getting Started with Workerman: Installation, Commands, and RPC Usage in PHP

Workerman is a high‑performance PHP socket service framework that enables developers to build various network applications such as RPC services, chat rooms, and games.

Key features include multi‑process support, TCP/UDP handling, various application‑layer protocols, libevent‑based event loop for high concurrency, file change detection, smooth worker reload, telnet control, exception monitoring, long‑connection support, and the ability to run workers under specific users.

Installation

1. Download or clone the repository: https://github.com/walkor/workerman-JsonRpc 2. Install dependencies: composer install Start / Stop Commands

php start.php start -d
php start.php restart
php start.php reload
php start.php status
php start.php stop

RPC Application Usage

Server side : Service classes are placed in Applications/JsonRpc/Services. Example class User.php provides static methods such as getInfoByUid and getEmail.

<?php
class User {
    public static function getInfoByUid($uid) {
        // ....
    }
    public static function getEmail($uid) {
        // ...
    }
}

Client synchronous call :

<?php
include_once 'yourClientDir/RpcClient.php';
$address_array = array('tcp://127.0.0.1:2015','tcp://127.0.0.1:2015');
RpcClient::config($address_array);
$uid = 567;
$user_client = RpcClient::instance('User');
$ret_sync = $user_client->getInfoByUid($uid);

Client asynchronous call :

<?php
include_once 'yourClientDir/RpcClient.php';
$address_array = array('tcp://127.0.0.1:2015','tcp://127.0.0.1:2015');
RpcClient::config($address_array);
$uid = 567;
$user_client = RpcClient::instance('User');
$user_client->asend_getInfoByUid($uid);
$user_client->asend_getEmail($uid);
// other business logic …
$ret_async1 = $user_client->arecv_getEmail($uid);
$ret_async2 = $user_client->arecv_getInfoByUid($uid);
