Hi Michael, Thanks a lot for your response.
Basically I am selecting out "one row" from the database with multiple columns (should have told you that earlier) so it seems that unfortunately your elegant approach below might not work. Although some of the columns are text and some numeric I was planning to load them all into strings. Perhaps I could convert the output to strings on the fly or something? Otherwise I guess I could select the data into a temporary table and then loop through each column adding the value to my array - will search around for this. Can you tell I'm normally a php developer? :-) Thanks again, Z. ----- Original Message ----- > On Fri, Apr 01, 2005 at 03:22:58PM +1200, Zitan Broth wrote: > > > > I was wondering if there was an easy way of converting the output > > from a SELECT statement into an Array .....
