Where can I find reliable resources or documentation on handling email sending in PHP?

To handle email sending in PHP, you can use the built-in `mail()` function or a library like PHPMailer. PHPMailer is a popular library that provides more features and better support for sending emails. You can find reliable documentation and resources on handling email sending in PHP on the PHPMailer GitHub page, official PHP documentation, and various online tutorials.

// Using PHPMailer library to send an email
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 up the 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 up the email content
$mail->setFrom('from@example.com', 'Your Name');
$mail->addAddress('recipient@example.com', 'Recipient Name');
$mail->Subject = 'Test Email';
$mail->Body = 'This is a test email';

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