How can beginners troubleshoot issues with their PHP contact form, such as the form redirecting to Outlook instead of sending the message directly?

The issue of a PHP contact form redirecting to Outlook instead of sending the message directly may be due to incorrect form action or headers being set improperly. To solve this issue, ensure that the form action points to the correct PHP script handling the form submission and set the appropriate headers for sending emails.

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $to = "recipient@example.com";
    $subject = "Contact Form Submission";
    $message = $_POST["message"];
    $headers = "From: " . $_POST["email"] . "\r\n";
    
    if (mail($to, $subject, $message, $headers)) {
        echo "Message sent successfully";
    } else {
        echo "Failed to send message";
    }
}
?>
