How can PHP beginners approach creating a form that submits data and displays a confirmation message in the same file?

To create a form that submits data and displays a confirmation message in the same file, beginners can use PHP to check if the form has been submitted, process the form data, and then display a confirmation message. This can be achieved by checking if the form has been submitted using the isset() function, processing the form data if it has been submitted, and displaying a confirmation message using echo. 

<?php
if(isset($_POST['submit'])){
    // Process form data here
    $name = $_POST['name'];
    $email = $_POST['email'];
    
    // Display confirmation message
    echo "Thank you, $name! Your email address $email has been submitted.";
}
?>

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
    <label for="name">Name:</label>
    <input type="text" name="name" id="name"><br>
    
    <label for="email">Email:</label>
    <input type="email" name="email" id="email"><br>
    
    <input type="submit" name="submit" value="Submit">
</form>
