README

PlinkerRPC PHP client/server makes it really easy to link and execute generic PHP components on remote systems, while maintaining the feel of a local method call.

Docs: https://plinker-rpc.github.io/core

New changes in version 3 include:

Now compaible with PHP extension.
Built-in core components and info method added so components can be discovered.
Only one client instance is now needed, made use of __get() to dynamically set component.
User defined components/classes, so you can call your own code.
Both request and response is encrypted and signed.

Install

Require this package with composer using the following command:

$ composer require plinker/core

Additional Setup

This component does not require any additional setup.

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');

Server

Creating a server listener is done as follows:

Optional features:

Set a secret, which all clients will require.
Lock down to specific client IP addresses for addtional security.
Define your own classes in the classes array then access like above $client->class->method(), which can interface out of scope components or composer packages.
Define addtional key values for database connections etc, or you could pass the parameters through the client connection.

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

/**
 * Initialize plinker server.
 */
if (isset($_SERVER['HTTP_PLINKER'])) {
    // init plinker server
    echo (new \Plinker\Server([
        'secret' => 'a secret password',
        'allowed_ips' => [
            '127.0.0.1'
        ],
        'classes' => [
            'test' => [
                // path to file
                'classes/test.php',
                // addtional key/values
                [
                    'key' => 'value'
                ]
            ],
            // you can use namespaced classes
            'Foo\\Demo' => [
                // path to file
                'some_class/demo.php',
                // addtional key/values
                [
                    'key' => 'value'
                ]
            ],
            // ...
        ]
    ]))->listen();
}

Methods

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

Info

The info method returns defined endpoint methods and their parameters.

Call

$result = $client->info();

Response

Array
(
    [class] => Array
        (
            [Foo\Demo] => Array
                (
                    [config] => Array
                        (
                            [key] => value
                        )

                    [methods] => Array
