How can PHP developers optimize their database design to avoid the need for complex string manipulation in SQL queries?

PHP developers can optimize their database design by properly normalizing their database tables and using appropriate data types for columns. By structuring the database in a way that minimizes the need for complex string manipulation, developers can avoid the need for convoluted SQL queries. Additionally, utilizing PHP functions like prepared statements and parameter binding can help prevent SQL injection attacks and make queries more efficient. 

// Example of using prepared statements in PHP to avoid complex string manipulation in SQL queries
$stmt = $pdo->prepare("SELECT * FROM users WHERE username = :username");
$stmt->bindParam(':username', $username, PDO::PARAM_STR);
$stmt->execute();
$results = $stmt->fetchAll();
