How can PHP be utilized to prepopulate form fields with values before submission?

To prepopulate form fields with values before submission using PHP, you can pass the values through the URL parameters or by using session variables. By retrieving these values in the form fields, you can display them as default values when the form loads. 

<?php
// Set the default values for the form fields
$name = isset($_GET['name']) ? $_GET['name'] : '';
$email = isset($_GET['email']) ? $_GET['email'] : '';

// Use the default values in the form fields
echo '<form method="post" action="submit.php">';
echo 'Name: <input type="text" name="name" value="' . $name . '"><br>';
echo 'Email: <input type="email" name="email" value="' . $email . '"><br>';
echo '<input type="submit" value="Submit">';
echo '</form>';
?>
