What are the potential risks of SQL injection in PHP forum scripts and how can they be mitigated?

SQL injection in PHP forum scripts can allow malicious users to execute unauthorized SQL queries, potentially leading to data loss or unauthorized access to sensitive information. To mitigate this risk, developers should use prepared statements or parameterized queries to ensure that user input is properly sanitized before being executed as SQL queries. 

// Using prepared statements to mitigate SQL injection risk
$stmt = $pdo->prepare("SELECT * FROM users WHERE username = :username");
$stmt->bindParam(':username', $username);
$stmt->execute();
