How can PHP developers integrate email sending functionality into contact forms?

To integrate email sending functionality into contact forms, PHP developers can use the `mail()` function to send emails from the server. This function allows developers to specify the recipient email address, subject, message body, and additional headers. By including this function in the form submission process, developers can automatically send an email notification whenever a user submits a contact form. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $recipient = "youremail@example.com";
    $subject = "Contact Form Submission";
    $message = $_POST["message"];
    
    $headers = "From: " . $_POST["email"];
    
    if (mail($recipient, $subject, $message, $headers)) {
        echo "Email sent successfully!";
    } else {
        echo "Email sending failed.";
    }
}
?>
