PlinkerRPC - System

A system component which gives you access to server information.

Install

Require this package with composer using the following command:

$ composer require plinker/system

Client

Creating a client instance is done as follows:

<?php
require 'vendor/autoload.php';

/**
 * Initialize plinker client.
 *
 * @param string $server - URL to server listener.
 * @param string $config - server secret, and/or a additional component data
 */
$client = new \Plinker\Core\Client(
    'http://example.com/server.php',
    [
        'secret' => 'a secret password'
    ]
);

// or using global function
$client = plinker_client('http://example.com/server.php', 'a secret password');

Methods

Once setup, you call the class though its namespace to its method.

Enumerate

The enumerate method is used to call multiple methods in a single call to reduce RPC requests.

Parameter	Type	Description	Default
methods	string	array	A string or an array of methods
params	array	An array of params	[]

The method could be used to call a single method, or multiple with parameters.

Call

$client->system->enumerate([
    'arch',
    'hostname',
    'disks' => ['/'],
    'ping' => ['https://google.com'],
]);

// or single method
$client->system->enumerate('disks', ['/']);
