MySQL 5 - Mysqli_real_query vs mysqli_query

According to the PHP website, _query is the same as calling _real_query followed by _use_result or _store_result (Depending on the third parameter of _query). Is this the only difference between the two?

I presume not otherwise _real_query could get depreciated. As _query has the same functionality

the data they return is different. The _real_query will just return true or false where _query will return an actual result object depending on the query. Sometimes you do want to just run a query that doesn't need a result and/or query, but not use the result if a condition is met. By just getting back the true/false, you save the time of having to run the extra functions on the result.
