Are there specific PHP functions or methods that can help with controlling form display based on submission?

To control form display based on submission, you can use PHP to check if the form has been submitted and then conditionally display the form or the submission success message. You can achieve this by checking if the form has been submitted using the `$_SERVER['REQUEST_METHOD']` variable and then displaying the appropriate content based on that. 

<?php
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    // Form has been submitted, process the form data here
    echo "Form submitted successfully!";
} else {
    // Display the form
    echo '<form method="post" action="">
            <input type="text" name="name" placeholder="Enter your name">
            <input type="email" name="email" placeholder="Enter your email">
            <button type="submit">Submit</button>
          </form>';
}
?>
