New Comment:
Your code makes the assumption that one wants to print_r a variable
from the globals scope. print_r'ing a variable from a function won't
work:
<?php
$a = "grhgchlkmehvzfvehe";
function foobar() {
$a = array(1, 2, 5, 7, 8);
print_rc("a");
}
foobar();
?>
If such a limitation is acceptable for you: Put that to your default
library and use it, for a regular, internal, PHP function such a
limitation isn't acceptable.
I hope we can end this now.

Description:
------------
My reason for writing was to make PHP a bit more comfortable.
I dont want to spam. I have tried to email you besides this bug
reporting system at [EMAIL PROTECTED] without success.
You are doing your job for the same reason I do report this: idealism.
I first didnt understood what you meant with "variable container"
cause I have studied physics, not informatics.
Now I see the problematic that only the value and not the name is
given the function print_r.
My native language isnt english but german.
I dont know the internal means of PHP and if a method ".name" exists.
I only wanted to say it would be nice.
I think that is the critical point very often: first to say "Yes I
understand you, what you want is a good idea, unfortunately its not so
easy to realize."
<?php
function print_rc($variable_name)
{
global ${$variable_name};
echo "Array \$$variable_name\n {\n";
foreach(${$variable_name} as $key => $val) echo " [$key] =>
$val\n";
echo " }\n";
}
$arr = array(1,2,3);
print_rc('arr');
?>
This is doing what I want. And the problem is instead giving the value
to the function (print_r) here (print_rc) the name is given.
So my wish is incompatible with the current implementation of PHPs
print_r.
Its a pity.
Its my part to give this suggestion and its your part to decide
whether its a nice thing and when "yes" how that can be implemented.
You can see now that with an optional second parameter in print_r
(interpreting the given variable as a name) or an additional new php-
function print_rc my wish is possible. With the recent implementation
of print_r it may not be possible.
I dont want to waste my time describing the current state. I want to
give a suggestion for the future. Realisation isnt impossible.
