RE: [PHP] Varible Varibles

I think you're missing the point of variable variables. <? $a = 'foo'; $$a = 'bar'; echo "$a $$a"; ?> After the first use of $$a, you now have a variable called $foo with a value of 'bar'. So your echo would be echo "$a $foo"; I kind of consider variable variables the poor mans array. Most any solution you think of with variable variables could be better solved by using arrays. ---John Holmes... > -----Original Message----- > From: Peter [mailto:php@vfsa.com.au] > Sent: Wednesday, June 12, 2002 10:42 PM > To: Php > Subject: [PHP] Varible Varibles > > howdy, > I'm just curious here about varible varibles ...
