How can XAMPP from ApacheFriends.org be helpful in resolving PHP script functionality issues?

Issue: XAMPP can be helpful in resolving PHP script functionality issues by providing a local server environment for testing and debugging scripts before deploying them live. This allows developers to identify and fix any errors or bugs in their code without affecting the live website.

// Example PHP code snippet using XAMPP to debug script functionality
// Connect to a MySQL database using XAMPP local server environment

$servername = "localhost";
$username = "root";
$password = "";
$dbname = "myDB";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} else {
    echo "Connected successfully";
}
