Can PHP be used to create dynamic content on a website, or is JavaScript necessary for such tasks?

PHP can be used to create dynamic content on a website. While JavaScript is commonly used for client-side interactions, PHP is a server-side language that can generate dynamic content based on user input, database queries, or other server-side operations. By combining PHP with HTML, CSS, and JavaScript, you can create fully dynamic and interactive websites.

<?php
// Example PHP code to create dynamic content on a website
$dynamic_content = "Hello, world!";
echo $dynamic_content;
?>
