What common mistake did the user make in the PHP code that caused the browser to display the PHP file contents instead of processing the form input?

The common mistake the user made in the PHP code is not having a server environment set up to interpret PHP code. This caused the browser to display the PHP file contents instead of processing the form input. To solve this issue, the user needs to ensure that their PHP file is being served by a web server that can interpret PHP code. 

<?php
// Ensure that the PHP file is being served by a web server that can interpret PHP code
// For example, using XAMPP, WAMP, MAMP, or hosting on a server with PHP support
// Once the PHP environment is set up correctly, the form input should be processed as expected
?>
