New Comment:
And what's the bug here anyway? As it clearly says in the manual page
for get_object_vars(): "Gets the public properties of the given
object".
Private is not public and as the method is in context of the "Base"
class, why would it include private properties of extending class?
(Disclaimer: This is how _I_ understand this :)
You get expected result if you define getProperties() method in the
Child class tool..

Just a note about bug #42814: "No feedback" is not same as "Closed" in
which case there would be an entry in the NEWS file about a fixed bug..

Description:
------------
I read the Bug #42814 which is supposed to be closed, however, I have
reproduced this bug in the last version 5.2.6
this is a sample code :
<?php
class Base {
private $basePrivateProperty;
protected $baseprotectedProperty;
function getProperties () {
return get_object_vars ( $this );
}
}
class Child extends Base {
private $childPrivateProperty;
protected $childprotectedProperty;
}
echo "Base :<br/>\n";
$father = new Base();
var_dump($father->getProperties());
echo "<br/>Child :<br/>\n";
$children = new Child();
var_dump($children->getProperties());
?>
Running this sample code
Result on different versions of php 5:
PHP version 5.2.0 to 5.2.3 :
Base :
array(2) { ["basePrivateProperty"]=> NULL ["baseprotectedProperty"]=>
NULL }
Child :
array(3) { ["childPrivateProperty"]=> NULL ["childprotectedProperty"]=>
NULL ["baseprotectedProperty"]=> NULL }
PHP version 5.2.4 to 5.2.6:
Base :
array(2) { ["basePrivateProperty"]=> NULL ["baseprotectedProperty"]=>
NULL }
Child :
array(3) { ["childprotectedProperty"]=> NULL ["basePrivateProperty"]=>
NULL ["baseprotectedProperty"]=> NULL }
I think the good behaviour is the one returned by versions 5.2.0 to
5.2.3.
in 5.2.4 version and up, the child can access to his parent's private
property but not to his own private property
Reproduce code:
---------------
<?php
class Base {
private $basePrivateProperty;
protected $baseprotectedProperty;
function getProperties () {
return get_object_vars ( $this );
}
}
class Child extends Base {
private $childPrivateProperty;
protected $childprotectedProperty;
}
echo "Base :<br/>\n";
$father = new Base();
var_dump($father->getProperties());
echo "<br/>Child :<br/>\n";
$children = new Child();
var_dump($children->getProperties());
?>
Expected result:
----------------
Base :
array(2) { ["basePrivateProperty"]=> NULL ["baseprotectedProperty"]=>
NULL }
Child :
array(3) { ["childPrivateProperty"]=> NULL ["childprotectedProperty"]=>
NULL ["baseprotectedProperty"]=> NULL }
Actual result:
--------------
Base :
array(2) { ["basePrivateProperty"]=> NULL ["baseprotectedProperty"]=>
NULL }
Child :
array(3) { ["childprotectedProperty"]=> NULL ["basePrivateProperty"]=>
NULL ["baseprotectedProperty"]=> NULL }
