When should a web server be used instead of XAMPP for PHP applications?

A web server should be used instead of XAMPP for PHP applications when deploying the application to a production environment. Web servers like Apache or Nginx are designed for handling production traffic efficiently and securely. XAMPP, on the other hand, is more suited for local development and testing purposes. 

<?php
// Sample PHP code snippet for connecting to a MySQL database using a web server
$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);
}
echo "Connected successfully";
?>
