What are best practices for debugging PHP code when encountering SQL syntax errors?

When encountering SQL syntax errors in PHP code, it is important to carefully review the SQL query being executed to identify any syntax issues such as missing quotes, incorrect table or column names, or improper use of SQL keywords. It is also helpful to use tools like PHP's error reporting functions or SQL debugging tools to pinpoint the exact location of the error. Additionally, consider using prepared statements or parameterized queries to prevent SQL injection attacks and minimize syntax errors. 

// Example code snippet demonstrating the use of prepared statements to prevent SQL syntax errors
$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);
