Why is it recommended to avoid using the mail() function in PHP according to one of the forum users?

The mail() function in PHP is not recommended for sending emails due to security vulnerabilities and potential for abuse, such as spamming. It is better to use a dedicated email library like PHPMailer or Swift Mailer, which provide more features, better security, and easier implementation of email functionality. 

// Example of sending an email using PHPMailer library
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

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

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

// Set up the SMTP server settings
$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'your@example.com';
$mail->Password = 'your_password';
$mail->SMTPSecure = 'ssl';
$mail->Port = 465;

// Set the email content
$mail->setFrom('your@example.com', 'Your Name');
$mail->addAddress('recipient@example.com', 'Recipient Name');
$mail->Subject = 'Test Email';
$mail->Body = 'This is a test email sent using PHPMailer';

// Send the email
if (!$mail->send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent';
}
