Re: [PHP] Functions with Static Variables vs. Classes

For some simple applications I use a function to collect values in a static
variable and to return them when called in a special way, just like this
(fairly senseless) example:
function example($elem='') {
static $store = array();

AFAIK the above line should cause an error on the second run of the
function, as you declare the same static variable for the second time.

or am I wrong?

if (!func_num_args()) return($store);
... do something with $elem ...
$store[] = $elem;
}
I would call this a singleton-micro-class, as it works like a class with
data and methods, but there is always only one of it, having only one
method.

Why do I? Because I dont need to worry about variablescope as if I would use
global variables and I dont have to initialize an object before the first
call (with the scope-problem again). I simply can call it everywhere and
everytime.

Do you have any comments to this approach?
