Are there any best practices for setting up a PHP script to fax from a server?

Setting up a PHP script to fax from a server involves using a fax API or service provider to send faxes programmatically. One best practice is to securely store any API credentials or sensitive information in environment variables to prevent exposing them in the code.

// Include the library for sending faxes
require_once('vendor/autoload.php');

// Set up your API credentials securely using environment variables
$apiKey = getenv('FAX_API_KEY');
$apiSecret = getenv('FAX_API_SECRET');

// Initialize the fax client with your credentials
$client = new FaxClient($apiKey, $apiSecret);

// Send a fax using the client
$response = $client->sendFax('+15551234567', 'example.pdf');

// Handle the response from the API
if ($response->success) {
    echo 'Fax sent successfully!';
} else {
    echo 'Failed to send fax: ' . $response->error;
}
