## #16286 — Marcus Boerger — 2005-05-21T14:33:44+00:00

Hello internals,

  i want to chnage the output of `print_r()` and `var_dump()` so that it
shows the class a private property was declared in. The problem is that at
the moment both only state that the property is private so that you cannot
see which class level it belongs to and if there is any derived class with
a private property having the same name you cannot distinguish them.

See patch attached.

Here is the output of the unpatched version:
php > class T {
php { protected $pro = 1;
php { private $pri = 2;
php { public $pub = 3;
php { }
ew T;
php > $o = new T;
php > print_r($o);
T Object
(
    [pro:protected] => 1
    [pri:private] => 2
    [pub] => 3
)
php > class TT extends T {
php { private $pri = 4;
php { }
php > $oo = new TT;
php > print_r($oo);
TT Object
(
    [pri:private] => 4
    [pro:protected] => 1
    [pri:private] => 2
    [pub] => 3
)
php >

Here is the output of the patched version:
php > class T {
php { protected $pro = 1;
php { private $pri = 2;
php { public $pub = 3;
php { }
php > $o = new T;
php > print_r($o);
T Object
(
    [pro:protected] => 1
    [pri:private:T] => 2
    [pub] => 3
)
php > class TT extends T {
php { private $pri = 4;
php { }
php > $oo = new TT;
php > print_r($oo);
TT Object
(
    [pri:private:TT] => 4
    [pro:protected] => 1
    [pri:private:T] => 2
    [pub] => 3
)

If nobody objects i'll apply this tomorrow.

If we're going to change it, can we make it "visibility:class:name"
instead, as this seems more intuitive and readable.

eg:  private:TT:pri
