What are some key considerations for integrating PHP functionality with website design?

When integrating PHP functionality with website design, it is important to ensure that the PHP code is properly embedded within the HTML structure of the website. This means using PHP tags to enclose the PHP code within the HTML file. Additionally, it is crucial to sanitize user input to prevent security vulnerabilities such as SQL injection attacks. Lastly, make sure to test the functionality thoroughly to ensure that it works as expected on the website. 

<?php
// PHP code to sanitize user input
$user_input = $_POST['user_input'];
$sanitized_input = filter_var($user_input, FILTER_SANITIZE_STRING);
?>
