What are some best practices for creating complex websites using PHP and MySQL?

Issue: When creating complex websites using PHP and MySQL, it is important to follow best practices to ensure efficient and secure functionality. One key practice is to use prepared statements to prevent SQL injection attacks and improve performance. PHP Code Snippet: 

// Establish a connection to the MySQL database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";
$conn = new mysqli($servername, $username, $password, $dbname);

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

// Prepare a SQL statement using prepared statements
$stmt = $conn->prepare("SELECT * FROM users WHERE username = ?");
$stmt->bind_param("s", $username);

// Execute the statement
$stmt->execute();

// Bind the results to variables
$stmt->bind_result($id, $username, $email);

// Fetch the results
$stmt->fetch();

// Close the statement and connection
$stmt->close();
$conn->close();
