    Hi

    According to this article, get_var is automatically cached. Does that mean i do not need to explicitly cache it in my own php call?

    A moderator over on buddypress.org says, “no, you have to explicity cache it, otherwise the results will not be cached.”

    What’s the correct answer?

    thx!

    It depends on what cache you’re referring to. The result is automatically saved in $wpdb->last_result. Not technically a true cache, and the value is overwritten as soon as another query is run. Thus, if you want to use the result later, you’d best explicitly save it yourself. $last_result is only useful when used immediately as part of the same get_var() process.
