What are the best practices for handling SQL injection vulnerabilities in PHP functions like the one mentioned in the thread?

SQL injection vulnerabilities can be mitigated by using prepared statements and parameterized queries in PHP functions that interact with a database. This helps prevent malicious SQL code from being injected into queries, protecting the database from potential attacks. 

// Example of using prepared statements to prevent SQL injection
$stmt = $pdo->prepare("SELECT * FROM users WHERE username = :username AND password = :password");
$stmt->bindParam(':username', $username);
$stmt->bindParam(':password', $password);
$stmt->execute();
