How can PHP be used to send email notifications or confirmations to users after submitting a form on a website?

To send email notifications or confirmations to users after submitting a form on a website, you can use the PHP `mail()` function. This function allows you to send an email from your server to the specified recipient email address. You can customize the email content, subject, and sender information within the function. 

<?php
// Retrieve form data
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];

// Set recipient email address
$to = 'recipient@example.com';

// Set email subject
$subject = 'Form Submission Confirmation';

// Compose email message
$body = "Hello $name, \n\nThank you for submitting the form. We have received your message: \n$message";

// Set sender email address
$from = 'sender@example.com';

// Send email
$mail = mail($to, $subject, $body, "From: $from");

// Check if email was sent successfully
if ($mail) {
    echo 'Email sent successfully';
} else {
    echo 'Email sending failed';
}
?>
