What is the difference between PHP and Javascript in terms of execution location?

PHP is a server-side language, meaning it is executed on the server before the page is sent to the client's browser. On the other hand, JavaScript is a client-side language, meaning it is executed on the client's browser after the page has been received. This difference in execution location affects how each language interacts with the server and the client's browser.

<?php
// PHP code snippet
echo "Hello, World!";
?>
