In the context of the forum thread, what are some potential drawbacks of directly accessing and manipulating data from a database in PHP?

Directly accessing and manipulating data from a database in PHP can lead to security vulnerabilities such as SQL injection attacks if user input is not properly sanitized. To prevent this, it's recommended to use prepared statements with parameterized queries to securely interact with the database. 

// Connect to the database
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');

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

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

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

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