### Installing PHP SDK Dependencies with Composer

Source: https://github.com/chipasia/chip-php-sdk/blob/main/examples/README.md

This command uses Composer, a dependency manager for PHP, to install all required libraries and packages for the CHIP PHP SDK. It ensures that all necessary components are available before running the application.

```Bash
composer install
```

### Running PHP Development Server Locally

Source: https://github.com/chipasia/chip-php-sdk/blob/main/examples/README.md

This command starts a built-in PHP development server, making the application accessible locally at `localhost:7001`. This is useful for testing and debugging, especially when combined with tools like ngrok for external access to callback and webhook endpoints.

```Bash
php -S localhost:7001
```

### Creating a Purchase with Chip PHP SDK

Source: https://github.com/chipasia/chip-php-sdk/blob/main/README.md

This example demonstrates how to initialize the Chip API and create a new purchase. It sets up client details, product information, and defines redirect/callback URLs, then uses `createPurchase` to generate a checkout URL for redirection.

```PHP
<?php
  require_once 'vendor/autoload.php';
  $chip = new \Chip\ChipApi($config['brand_id'], $config['api_key'], $config['endpoint']);
  $client = new \Chip\Model\ClientDetails();
  $client->email = 'test@example.com';
  $purchase = new \Chip\Model\Purchase();
  $purchase->client = $client;
  $details = new \Chip\Model\PurchaseDetails();
  $product = new \Chip\Model\Product();
  $product->name = 'Test';
  $product->price = 100;
  $details->products = [$product];
  $purchase->purchase = $details;
  $purchase->brand_id = $config['brand_id'];
  $purchase->success_redirect = 'https://yourdomain.com/redirect.php?success=1';
  $purchase->success_callback = 'https://yourdomain.com/callback.php?success=0';
  $purchase->failure_redirect = 'https://yourdomain.com/redirect.php?success=0';

  $result = $chip->createPurchase($purchase);

  if ($result && $result->checkout_url) {
    // Redirect user to checkout
    header("Location: " . $result->checkout_url);
    exit;
  }
```

### Installing Chip PHP SDK with Composer

Source: https://github.com/chipasia/chip-php-sdk/blob/main/README.md

These commands are used to install or update the Chip PHP SDK and its dependencies after configuring the `composer.json` file. `composer install` installs dependencies from `composer.lock`, while `composer update` resolves and updates them to their latest compatible versions.

```Bash
composer install
# OR
composer update
```

### Configuring Composer for Chip PHP SDK

Source: https://github.com/chipasia/chip-php-sdk/blob/main/README.md

This snippet shows how to configure your `composer.json` file to include the Chip PHP SDK. It adds a VCS repository for the SDK and specifies the required package and version, enabling Composer to locate and install the library.

```PHP
"repositories": [
  ...
  {
      "type": "vcs",
      "url": "git@github.com:CHIPAsia/chip-php-sdk.git"
  }
],
"require": {
    "chip/chip-sdk-php": "^1.0"
}
```

### Configuring CHIP PHP SDK Credentials

Source: https://github.com/chipasia/chip-php-sdk/blob/main/examples/README.md

This PHP array defines the essential configuration parameters for the CHIP PHP SDK, including `brand_id`, `api_key`, `endpoint`, `basedUrl`, and `webhook_public_key`. These values must be replaced with actual credentials obtained from the CHIP Merchant Portal's Developer section to ensure proper API communication and webhook verification.

```PHP
// config.php
<?php

return [
	'brand_id' => '<<BRAND_ID>>',
	'api_key' => '<<API_KEY>>',
	'endpoint' => 'https://gate.chip-in.asia/api/v1/',
  	'basedUrl' => '<<DOMAIN_URL>>',
  	'webhook_public_key' => "<<WEBHOOK_PUBLIC_KEY>>"
];
```

--------------------------------

### Running Tests for Chip PHP SDK

Source: https://github.com/chipasia/chip-php-sdk/blob/main/README.md

This command executes the PHPUnit test suite for the Chip PHP SDK. It runs all tests located in the `tests` directory, ensuring the library's functionality and stability.

```Bash
./vendor/bin/phpunit tests
```
