RE: [PHP] Variable Next To Variable?

personally, that's what i would do. dealing with arrays usually makes the code a lot cleaner and easier to follow than using awkward constructs like ${$C_Last}{$i} and besides, if you ever wanted to expand your code, you could easily pass the entire array to a function like so: children( $C_Last ); if you used individual variables, you could not do that in any easy or efficient way. > -----Original Message----- > From: Jeff Oien [mailto:jeff@webdesigns1.com] > Sent: Wednesday, July 11, 2001 1:29 PM > To: PHP > Subject: FW: [PHP] Variable Next To Variable? > > > What I'm doing is having a form page ask, "How many > children do you want to sign up?"
