Overview

The Mobile Money Payment package provides a flexible and extensible solution for integrating mobile money payment services into PHP applications. It currently supports Tmoney and Flooz payment services, with an architecture that allows easy addition of new payment providers.

Features

• Support for multiple payment services (currently Tmoney and Flooz)
• Extensible architecture using the Strategy pattern
• Standardized payment responses across different services
• Flexible Flooz counter management system
• Easy integration with various PHP applications, including Symfony

Requirements

• PHP 8.2 or higher
• Symfony HTTP Client

Installation

Install the package via Composer:

composer geekabel/mobile-money-payment

Basic Usage

Setting up the Payment Manager

use MobileMoneyPayment\PaymentManager;
use MobileMoneyPayment\Service\TmoneyService;
use MobileMoneyPayment\Service\FloozService;
use MobileMoneyPayment\Service\DefaultFloozCounterManager;

// Create service instances
$tmoneyService = new TmoneyService(
    $httpClient,
    $logger,
    'tmoney_username',
    'tmoney_password',
    'tmoney_alias',
    'https://tmoney-api-url.com'
);

$floozService = new FloozService(
    $httpClient,
    $logger,
    new DefaultFloozCounterManager(),
    'flooz_username',
    'flooz_password',
    'flooz_key',
    'flooz_merchant_name',
    'flooz_partner_msisdn',
    'https://flooz-api-url.com'
);

// Create and set up the Payment Manager
$paymentManager = new PaymentManager();
$paymentManager->addService('tmoney', $tmoneyService);
$paymentManager->addService('flooz', $floozService);

Making a Payment

$response = $paymentManager->pay('tmoney', '1234567890', 100.00, 'REF123', 'Payment for order #123');

if ($response->success) {
    echo "Payment successful! Transaction ID: " . $response->transactionId;
} else {
    echo "Payment failed: " . $response->message;
}

Checking Payment Status

$status = $paymentManager->checkStatus('flooz', 'REF123');

echo "Payment status: " . $status->status;

Extending the Package

Adding a New Payment Service

1. Create a new class that implements PaymentServiceInterface:

use MobileMoneyPayment\Interface\PaymentServiceInterface;
use MobileMoneyPayment\Model\PaymentResponse;

class NewPaymentService implements PaymentServiceInterface
{
    public function pay(string $phone, float $amount, string $reference, string $description = ''): PaymentResponse
    {
        // Implement payment logic
    }

    public function checkStatus(string $reference): PaymentResponse
    {
        // Implement status check logic
    }
}

1. Add the new service to the Payment Manager:

$newService = new NewPaymentService(/* ... */);
$paymentManager->addService('new_service', $newService);

Custom Flooz Counter Manager

1. Create a class that implements FloozCounterManagerInterface:

use MobileMoneyPayment\Interface\FloozCounterManagerInterface;

class CustomFloozCounterManager implements FloozCounterManagerInterface
{
    public function getAndIncrementCounter(): int
    {
        // Implement custom counter logic
    }
}

1. Use the custom manager when creating the Flooz service:

$customCounterManager = new CustomFloozCounterManager();
$floozService = new FloozService(
    $httpClient,
    $logger,
    $customCounterManager,
    // ... other parameters
);

Advanced Usage

Error Handling

The package uses PaymentException for specific payment-related errors. It's recommended to catch these exceptions:

use MobileMoneyPayment\Exception\PaymentException;

try {
    $response = $paymentManager->pay('tmoney', '1234567890', 100.00, 'REF123');
} catch (PaymentException $e) {
    echo "Payment error: " . $e->getMessage();
} catch (\Exception $e) {
    echo "Unexpected error: " . $e->getMessage();
}

Logging

The package accepts a PSR-3 compatible logger. You can provide your own logger implementation for custom logging behavior:

use Monolog\Logger;
use Monolog\Handler\StreamHandler;

$logger = new Logger('payment');
$logger->pushHandler(new StreamHandler('path/to/your.log', Logger::DEBUG));

$tmoneyService = new TmoneyService(
    $httpClient,
    $logger,
    // ... other parameters
);
