How can beginners distinguish between server-side and client-side technologies when working with PHP?

Beginners can distinguish between server-side and client-side technologies by understanding that server-side technologies, like PHP, run on the server and process data before sending it to the client's browser. On the other hand, client-side technologies, like HTML, CSS, and JavaScript, run on the client's browser and interact directly with the user. To work effectively with PHP, beginners should focus on writing server-side code that handles data processing, database interactions, and server requests. 

<?php
// Server-side code example
// This PHP script processes form data and sends a response to the client

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = $_POST['name'];
    $email = $_POST['email'];
    
    // Process the form data (e.g., save to a database)
    
    // Send a response back to the client
    echo "Thank you for submitting the form, $name!";
}
?>
