Are there specific coding conventions or syntax rules in PHP that can help prevent security breaches like the one experienced in the forum thread?

The security breach in the forum thread was caused by directly inserting user input into SQL queries, making the application vulnerable to SQL injection attacks. To prevent this, developers should use prepared statements with parameterized queries to sanitize user input and prevent malicious SQL code execution. 

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