Description:
------------
Keeping in mind that print_r is a function this
function should know its parameters. Shouldn't it?

So when i use print_r($class);

why not outputting

Array $class
(
    [0] => K02
    [1] => K03
    [2] => K01
    [3] => K04
    [4] => K09
)

?



I know what I can do myself, but I think it would be of comfort when 
php itself would mention the name of the shown array.

Do you understand me?

Extending this functions features should not have any disadvantages 
except implementing maybe one line of code.

Kind regards, R?diger

Still not possible, unless you can solve this in PHP:

<?php
function foo($a) {
  // How do you print $foo here? - Right it's impossible.
}

f($foo);
?>
