What are the main differences between PHP and JavaScript in terms of handling actions like button clicks?

PHP is a server-side language, meaning it runs on the server before the page is loaded on the client's browser. This means that PHP cannot directly handle client-side actions like button clicks. On the other hand, JavaScript is a client-side language, allowing it to interact with elements on the webpage, such as handling button clicks.

// PHP code cannot directly handle button clicks, as it is a server-side language
// If you need to handle button clicks, you will need to use JavaScript instead
