// Example: Sending email using PHPMailer with SMTP
// 1. Download PHPMailer: https://github.com/PHPMailer/PHPMailer
//    Place the PHPMailer src/ folder in your project (e.g., includes/PHPMailer/)
// 2. Use the following code to send an email:

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'includes/PHPMailer/Exception.php';
require 'includes/PHPMailer/PHPMailer.php';
require 'includes/PHPMailer/SMTP.php';
require 'includes/env.php';

$mail = new PHPMailer(true);
try {
    // SMTP server configuration
    $mail->isSMTP();
    $mail->Host = env('SMTP_HOST', 'smtp.gmail.com'); // SMTP server (e.g., smtp.gmail.com)
    $mail->SMTPAuth = true;
    $mail->Username = env('SMTP_USERNAME', ''); // Your SMTP username
    $mail->Password = env('SMTP_PASSWORD', '');    // Your SMTP password or app password
    $mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS; // Encryption (tls or ssl)
    $mail->Port = (int) env('SMTP_PORT', 587); // SMTP port (587 for TLS, 465 for SSL)

    // Email settings
    $mail->setFrom(env('SMTP_FROM', env('SMTP_USERNAME', '')), env('SMTP_FROM_NAME', 'CAI Admin'));
    $mail->addAddress('caiofficial03@gmail.com', 'CAI Admin');
    $mail->Subject = 'Test SMTP Email';
    $mail->Body    = 'This is a test email sent using SMTP and PHPMailer.';

    $mail->send();
    echo 'Message has been sent';
} catch (Exception $e) {
    echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}
