What are some alternative methods to send emails in PHP besides using the mail() function?

Using PHP's mail() function to send emails can sometimes be unreliable due to server configurations or limitations. An alternative method to send emails in PHP is to use a third-party email service provider like SendGrid, Mailgun, or SMTP. These services offer more reliable email delivery and additional features like tracking and analytics. 

// Using PHPMailer with SMTP to send emails

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

require 'vendor/autoload.php'; // Include PHPMailer autoloader

// Create a new PHPMailer instance
$mail = new PHPMailer();

// Set SMTP settings
$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'your@example.com';
$mail->Password = 'your_password';
$mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;
$mail->Port = 587;

// Set email content
$mail->setFrom('your@example.com', 'Your Name');
$mail->addAddress('recipient@example.com', 'Recipient Name');
$mail->Subject = 'Subject of the email';
$mail->Body = 'This is the body of the email';

// Send the email
if (!$mail->send()) {
    echo 'Error: ' . $mail->ErrorInfo;
} else {
    echo 'Email sent successfully';
}
