I am writing some code that will format results of a search for

I need to split an array into several different arrays but I won't

before hand how many, so, I am looking for a way to dynamically
generate arrays for this purpose.
My present direction is to use the following code:
for($i = 0; $i < $c; $i++)
{ eval('$a_'.$i.' = array();'); }
Where '$c' is the derived number of arrays need to hold the
pieces of the bigger array. My confusion, though, is; since
these are created in the scope of the for loop, I don't know
if I can use them elsewhere in the code. The Global statement
sends them outside the scope of the function this code is in,
or does it? And I'm not even sure I am on the right track.
Perhaps someone can say yay or nay on the spot, if not
I can go back and do some experimenting.
PHP has only 2 places where "scope" changes:
#1 global "script" scope
#2 function [name] () { [scope change] }
Obviously, class properties are also bound to the class...
All of this is moot, however, as you are working WAY to hard to
pre-define the arrays.
PHP is quite happy to have you just do:
$a[7][13] = 42;
And it will define the arrays needed to make it work.
Using 'eval' here is DEFINITELY the right answer to the wrong
question. :-)
