Re: [PHP-DEV] Re: protected/private access and var_dump/print_r

[Andi Gutmans]

Fine with me. I'm not sure printing public is a bad idea. How many ppl 
actually use this in their application for purposes other than debugging?

I agree with Derick and Andrey in that if anything should be changed it 
is var_dump.

Reasoning: PPP is there to specify an interface, not to be used in a 
sandbox way. Both var_dump and print_r are for human inspection and I 
don't an advantage in hiding information there, quite the opposite.
I agree that showing all PPP makes more sense for these functions. They 
are mainly debugging tools and for human inspection. Information hiding 
is important on the language level itself.

So,
I have made a patch against HEAD :
http://hristov.com/andrey/projects/php_stuff/patches/var_dump.diff.2.txt
php -r 'class a{ protected $a=1; private $b=2;var $c=3;} $a=new a(); 
var_dump($a);'
produces :
object(a)#1 (3) {
  ["a:protected"]=>
  int(1)
  ["b:private"]=>
  int(2)
  ["c"]=>
  int(3)
}

I hope that everyone will be happy with this. var_dump() is still BC since 
it does not print ":public" on public properties.
