README

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 schema31/php-ci-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:

"schema31/php-ci-restserver": "^3.1"

or run

composer require schema31/php-ci-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 Schema31\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 Schema31\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' => '[e-mail]'],
            ['id' => 1, 'name' => 'Jim', 'email' => '[e-mail]'],
        ];

        $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 );
            }
        }
    }
}
