CodeIgniter RestServer

A fully RESTful server implementation for CodeIgniter using one library, one config file and one controller.

Requirements

PHP 7.2 or greater
CodeIgniter 3.1.11+

Installation

composer require chriskacerguis/codeigniter-restserver

Usage

CodeIgniter Rest Server is available on Packagist (using semantic versioning), and installation via composer is the recommended way to install Codeigniter Rest Server. Just add this line to your composer.json file:

"chriskacerguis/codeigniter-restserver": "^3.1"

or run

composer require chriskacerguis/codeigniter-restserver

Note that you will need to copy rest.php to your config directory (e.g. application/config)

Step 1: Add this to your controller (should be before any of your code)

use chriskacerguis\RestServer\RestController;

Step 2: Extend your controller

class Example extends RestController

Basic GET example

Here is a basic example. This controller, which should be saved as Api.php, can be called in two ways:

http://domain/api/users/ will return the list of all users
http://domain/api/users/id/1 will only return information about the user with id = 1

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

use chriskacerguis\RestServer\RestController;

class Api extends RestController {

    function __construct()
    {
        // Construct the parent class
        parent::__construct();
    }

    public function users_get()
    {
        // Users from a data store e.g. database
        $users = [
            ['id' => 0, 'name' => 'John', 'email' => '[email protected]'],
            ['id' => 1, 'name' => 'Jim', 'email' => '[email protected]'],
        ];

        $id = $this->get( 'id' );

        if ( $id === null )
        {
            // Check if the users data store contains users
            if ( $users )
            {
                // Set the response and exit
                $this->response( $users, 200 );
            }
            else
            {
                // Set the response and exit
                $this->response( [
                    'status' => false,
                    'message' => 'No users were found'
                ], 404 );
            }
        }
        else
        {
            if ( array_key_exists( $id, $users ) )
            {
                $this->response( $users[$id], 200 );
            }
            else
            {
                $this->response( [
                    'status' => false,
                    'message' => 'No such user found'
                ], 404 );
            }
        }
    }
}
