In the documentation it is said that if you use same column names the last one will win. That is so far ok.

However I think the following statement could be correctly transferred in an assoc. array:

SELECT tblOrderAddress.Street, tblDeliveryAdress.Street 
FROM tblCustomer AS tblOrderAddress, tblCustomer AS tblDeliveryAddress
WHERE .....;

It is correct that Street occurs twice as an attribute, but it is distinguishable by the preceding tablename.
Isn't it possible to change mysql_fetch_array, so that tablenames, if stated, are included in the assoc Array building process?
