I notice when I do queries in phpMyAdmin, it often uses backticks for table names and fields:

DELETE  FROM  `users`  WHERE  `users`.`id`  =11 LIMIT 1

Since they aren't required, is there any real benefit to use backticks in my script queries?

I don't really know the extra purpose of them.... but if you do your query withouth the backtickts proparly, you don't need to worry.

Using "backticks" on database and column names avoids any issues where the entity name is a reserved word.
