What are the benefits of using proper syntax and variable handling in PHP SQL queries?

Using proper syntax and variable handling in PHP SQL queries helps prevent SQL injection attacks, improves code readability, and ensures the query runs smoothly without errors. By using prepared statements and binding parameters, you can securely pass user input to the database without risking malicious SQL injection. 

// Example of using prepared statements and binding parameters in PHP SQL query
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');

$stmt = $pdo->prepare('SELECT * FROM users WHERE username = :username');
$stmt->bindParam(':username', $username, PDO::PARAM_STR);
$stmt->execute();

$results = $stmt->fetchAll(PDO::FETCH_ASSOC);
