What are the best practices for setting up and running PHP scripts using xampp?

Issue: When setting up and running PHP scripts using XAMPP, it is important to follow best practices to ensure smooth execution and security. This includes properly configuring XAMPP settings, organizing files in the htdocs directory, using secure coding practices, and regularly updating PHP and XAMPP versions. Code snippet:

<?php
// Sample PHP script to demonstrate best practices for setting up and running PHP scripts using XAMPP

// Ensure error reporting is enabled for debugging
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Connect to the MySQL database using PDO
$dsn = 'mysql:host=localhost;dbname=testdb';
$username = 'root';
$password = '';
try {
    $pdo = new PDO($dsn, $username, $password);
} catch (PDOException $e) {
    die('Connection failed: ' . $e->getMessage());
}

// Query the database
$stmt = $pdo->query('SELECT * FROM users');
while ($row = $stmt->fetch()) {
    echo $row['username'] . '<br>';
}

// Close the database connection
$pdo = null;
?>
