How can PHP developers ensure that their code is optimized for data formatting and searching in a MySQL database?

To optimize PHP code for data formatting and searching in a MySQL database, developers can use prepared statements to prevent SQL injection, utilize indexes on frequently searched columns, and minimize the amount of data retrieved from the database by using specific SELECT queries. 

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

// Example of utilizing indexes on frequently searched columns
$stmt = $pdo->query("CREATE INDEX idx_username ON users (username)");

// Example of minimizing data retrieval using specific SELECT queries
$stmt = $pdo->query("SELECT id, username FROM users WHERE role = 'admin'");
