What are the potential issues with using MySQL functions in PHP for database queries, and what are the recommended alternatives?

Using MySQL functions in PHP for database queries can lead to security vulnerabilities such as SQL injection attacks. It is recommended to use prepared statements with parameterized queries to prevent these vulnerabilities and ensure safer database interactions. 

// Using prepared statements with parameterized queries
$stmt = $pdo->prepare("SELECT * FROM users WHERE username = :username");
$stmt->bindParam(':username', $username);
$stmt->execute();
$results = $stmt->fetchAll();
