Following on the same subject (kinda) of Variable Variables... i have
actually wondered this before... is there a difference between these 2
blocks?? (both should print "worldhello" if i am not mistaken, but is there
a difference in how the nested variable is handled when it's inside curly
braces?):
$a = "hello";
$hello = "world";
print($$a.$a);
------ and ------
$a = "hello";
$hello = "world";
print(${$a}.$a);

This would certainly work, but I got a suggestion for using <select
name="array[]" multiple> that i think will be a much cleaner solution.
Thanks!
