Are there any best practices for securely accessing databases using Prepared Statements in PHP?

When accessing databases in PHP, it is important to use Prepared Statements to prevent SQL injection attacks. Prepared Statements separate SQL logic from data input, making it more secure. To implement this, use parameterized queries with placeholders for user input. 

// Establish a database connection
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');

// Prepare a SQL statement with placeholders
$stmt = $pdo->prepare('SELECT * FROM users WHERE username = :username');

// Bind parameters to placeholders
$stmt->bindParam(':username', $username);

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

// Fetch results
$results = $stmt->fetchAll();
