How can PHP developers ensure they are following proper coding conventions when writing SQL queries?

PHP developers can ensure they are following proper coding conventions when writing SQL queries by using parameterized queries instead of concatenating user inputs directly into the query string. This helps prevent SQL injection attacks and ensures that the query is properly formatted. Additionally, developers should use consistent naming conventions for tables, columns, and variables to make the code more readable and maintainable. 

// Example of using parameterized queries in PHP to ensure proper coding conventions when writing SQL queries
$pdo = new PDO('mysql:host=localhost;dbname=test', 'username', 'password');
$stmt = $pdo->prepare('SELECT * FROM users WHERE username = :username');
$stmt->bindParam(':username', $username, PDO::PARAM_STR);
$stmt->execute();
$results = $stmt->fetchAll();
