Do you have experience developing user interfaces on the client side?

Although PHP is mainly used for server-side development, experience in creating user interfaces on the client side is usually associated with HTML, CSS, and JavaScript.

If we talk about UI development, it is important to:

• Layout pages using HTML and CSS.
• Use JavaScript for interactivity.
• Work with frameworks or libraries (e.g., React, Vue.js) for more complex interfaces.

PHP can generate HTML code dynamically, but it is not responsible for client-side logic.

Example of a simple PHP script that outputs HTML:

<?php
echo "<h1>Hello, world!</h1>";
?>

For full-fledged client-side development, it is recommended to study frontend technologies separately.
