How can the use of backticks in SQL statements affect the readability and efficiency of PHP code?

Using backticks in SQL statements can improve readability by clearly indicating the beginning and end of table or column names, especially when they contain special characters or reserved words. However, excessive use of backticks can clutter the code and make it harder to read. In terms of efficiency, using backticks does not significantly impact the performance of PHP code, but it can make the code more maintainable and easier to debug. 

// Example of using backticks in SQL statements for readability
$query = "SELECT `id`, `first_name`, `last_name` FROM `users` WHERE `status` = 'active'";
$result = mysqli_query($conn, $query);

// Example of avoiding excessive use of backticks for better readability
$query = "SELECT id, first_name, last_name FROM users WHERE status = 'active'";
$result = mysqli_query($conn, $query);
