If you want to print the keys for all the arrays in the main array then
use allkeys.

hello,
I have a simple question, not really a problem this time.
I know that the function print_r() will print an array but if that
array has sub-arrays it prints everything and if you don't use more
command or a pipe of some kind that could be useless in some cases,
but I am just wondering, for an array that has several arrays in it,
is there a way to print the array names that are contained in the
"main array" but not the contents of each?
thanks
matt
