Thanks, I found the post from John Holmes and was able to reconstruct the
query in mysql.  But when I transferred that over to php and try to extract
an associative array from each record, I found that only one column came out
instead of two.

By simply changing the query from:
    $query = "select, from test1.table1 t1 join test2.table2
t2 on =";
    $query = "select as first, as last from test1.table1 t1
join test2.table2 t2 on =";
the associative array worked as desired.

I suspect what was happening originally was both columns when extracted from
the result and placed into the array were both stored under the index
"name".  By changing them to have unique field names "as first" and "as
last" allowed two different indexes.  Perhaps there is a way of extracting
data from the query result that will allow redundant names, but I don't know
what that is.

thanks for the help,
