HUBTEL GENERAL SERVICES SDK PHP

Introduction

This is a Framework for building Ussd applications in PHP against the Hubtel Programmable Services.

This project is ported from the original C# version and USSD Framework in PHP.

Purpose

There are ways to integrate with the Hubtel Programmable Services across programming languages. This project is particularly to integrate with PHP.

Specifications

• Application configuration settings
• PHP object oriented architecture
• Session storage Redis store or any RDMS
• Standards for development

Installation

1 Require Composer PHP General Services Framework https://github.com/hubtel/general-services-sdk-php can smoothly run on newer PHP versions. The Hubtel Programmable Services PHP SDK can be installed with Composer. Run this command:

$ composer require hubtel-gh/general-services-sdk-php

#OR Clone the repository unto your machine/server, then navigate into the project.

2 Create Session Storage with Redis or any RDMS For Redis, Create a Redis Store implementing \HubtelUssdFramework\SessionStore, Configure accordingly.

'scheme' => '',
'host'   => '',
'port'   => ''

3 Define the applications settings and in Index.php file

Ussd::process('logger file', 'RedisStore', 'USSDApp', 'USSDMain', 'Main startup method/action for the USSD('start')', 'server');

USSDApp - # the folder that contains all your ussd applications logic
USSDMain - # the main controller/class of your ussd logic
start - # the main action/function/method of your ussd logic 
storageType - # RedisStore
'./general.log' - # path to your logger file

Sample

    Ussd::process('./general.log', new RedisStore(), 'USSDApp', 'USSDMain', 'start', $_ENV['SERVER']);

Usage

Run the script using the following command

$ php -S (Server address)

Demo

...
    
    # Main startup method/action for the USSD initiates the USSD session
    public function start()
    {
        $menu = new \UssdFramework\UssdMenu();
        $menu->header($this->_header)
                ->createAndAddItem('List Items', 'list_items')
                ->createAndAddItem('Exit', 'close', 'Main');
        return $this->renderMenu($menu);
    }

     public function list_items()
    {$menuHeader = 'Menu Header';

        $menu = new \UssdFramework\UssdMenu();
        $menu->header($menuHeader)
                ->createAndAddItem('Sunday', 'e_menu')
                ->createAndAddItem('Monday', 'e_menu')
                ->createAndAddItem('Tuesday', 'e_menu')
                ->createAndAddItem('Wednesday', 'e_menu')
                ->createAndAddItem('Thurday', 'e_menu')
                ->createAndAddItem('Friday', 'e_menu')
                ->createAndAddItem('Saturday', 'e_menu')
                ->addItem(new \UssdFramework\UssdMenuItem('0', 'Back', 'e_menu'));

        return $this->renderMenu($menu);
    }

    # display the menu
    public function e_menu(){

        return $this->redirect('start');
    }

     # Close user's USSD session
    public function close()
    {
        # closing message
        $message = "$this->_header \n\nThank you for using our USSD service";
        return $this->render($message);
    }
