php mysqli use vtable name in returned array rather than actual table

If you have a php application that uses the mysqli function mysqli_fetch_field_direct then the table name array element uses the vtable name rather than actual name.

This is more problematic in the case where you have a query with a join where you have a column with the same name from 2 different tables being projected.

Here is an example output, don't have an actual php test case at this point.

Array

(

    [0] => Array

        (

            [$vtable_482] => Array

                (

                    [a] => 6

                    [b] => 5

                )

        )

)
