What are the advantages and disadvantages of using JavaScript versus PHP for managing server processes and user interactions?

When considering whether to use JavaScript or PHP for managing server processes and user interactions, it's important to weigh the advantages and disadvantages of each. JavaScript is typically used for client-side interactions, providing a more dynamic and interactive user experience. On the other hand, PHP is better suited for server-side processing, handling tasks like database interactions and form submissions. PHP code snippet: ``` <?php // Server-side processing example using PHP $servername = "localhost"; $username = "username"; $password = "password"; $dbname = "myDB"; // Create connection $conn = new mysqli($servername, $username, $password, $dbname); // Check connection if ($conn->connect_error) { die("Connection failed: " . $conn->connect_error); } $sql = "SELECT id, firstname, lastname FROM MyGuests"; $result = $conn->query($sql); if ($result->num_rows > 0) { // output data of each row while($row = $result->fetch_assoc()) { echo "id: " . $row["id"]. " - Name: " . $row["firstname"]. " " . $row["lastname"]. "<br>"; } } else { echo "0 results"; } $conn->close(); ?> ```
