It's a matter of preference, but I prefer to keep my query strings as lean as possible -- bear in mind that this version:

> > > 		$sql = "UPDATE newdacs
> > > 			SET emailfwd='$emailfwd',
> > > 			mformat='$mformat',
> > > 			filter_code='$filter_code'";

will include not only the linebreaks but also all the leading whitespace on every line.

Personally, I like the technique of breaking my query up logically onto multiple lines, but I also prefer not to include unnecessary whitespace in the constructed query.  In addition, it seems to me that the repetitive inclusion of "$sql .= " on every line is not only distracting but also slightly inefficient, as you perform a concatenation and assignment for every line -- by using the form I showed in my previous response, you can reduce this to just a concatenation per line, and a single assignment:

	$sql = "UPDATE newdacs"
 	      . "SET emailfwd='$emailfwd',"
 	      . "mformat='$mformat',"
 	      . "filter_code='$filter_code'";

Of course, this is all completely IMHO, and I wouldn't say that any of the other ways of doing it is absolutely wrong.

Cheers!

Mike
