What are the advantages of using Prepared Statements with PDO or mysqli_ over traditional SQL queries in PHP?

Using Prepared Statements with PDO or mysqli_ in PHP offers several advantages over traditional SQL queries. Prepared Statements help prevent SQL injection attacks by separating SQL code from user input. They also improve performance by allowing the database to compile the query once and execute it multiple times with different parameters. Additionally, Prepared Statements make code more readable and maintainable by separating the query logic from the data. 

// Using Prepared Statements with PDO
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

$stmt = $pdo->prepare("SELECT * FROM users WHERE username = :username");
$stmt->bindParam(':username', $username);
$stmt->execute();

while ($row = $stmt->fetch()) {
    // Process the results
}
