ReflectionClass::getParentClass
Looks like you can access public, protected, private variables by casting the object to an array (useful for Unit Testing). However casting to an array still won't allow you access to protected and private static variables.
In PHP 5.3.0+ use ReflectionProperty::setAccessable(true);
<?php
echo "PHP Version: ".phpversion()."\n";
class Foo {
public $foo = 'public';
protected $bar = 'protected';
private $baz = 'private';
public static $sfoo = 'public static';
protected static $sbar = 'protected static';
private static $sbaz = 'private static';
const COO = 'const';
}
$obj = new Foo;
$arr = (array)$obj;
print_r($arr);
echo "Accessing Public Static: ".Foo::$sfoo."\n";
// echo Foo::$sbar."\n"; // Fatal error: Cannot access protected property Foo::$sbar
// echo Foo::$sbaz."\n"; // Fatal error: Cannot access private property Foo::$sbaz
echo "Accessing Constant: ".Foo::COO."\n";
?>

[foo] => public
[*bar] => protected
[Foobaz] => private
)

ReflectionClass::getProperties
(PHP 5)
ReflectionClass::getProperties — Gets properties
Description
public array ReflectionClass::getProperties
([ int
$filter
] )Retrieves reflected properties.
Parameters
-
filter -
The optional filter, for filtering desired property types. It's configured using the ReflectionProperty constants, and defaults to all property types.
Return Values
An array of ReflectionProperty objects.
Examples
Example #1 ReflectionClass::getProperties() filtering example
This example demonstrates usage of the optional filter
parameter, where it essentially skips private properties.
<?php
class Foo {
public $foo = 1;
protected $bar = 2;
private $baz = 3;
}
$foo = new Foo();
$reflect = new ReflectionClass($foo);
$props = $reflect->getProperties(ReflectionProperty::IS_PUBLIC | ReflectionProperty::IS_PROTECTED);
foreach ($props as $prop) {
print $prop->getName() . "\n";
}
var_dump($props);
?>
The above example will output something similar to:
foo
bar
array(2) {
[0]=>
object(ReflectionProperty)#3 (2) {
["name"]=>
string(3) "foo"
["class"]=>
string(3) "Foo"
}
[1]=>
object(ReflectionProperty)#4 (2) {
["name"]=>
string(3) "bar"
["class"]=>
string(3) "Foo"
}
}

It appears the filter parameter accepts a long value that is one of ReflectionProperty::IS_STATIC, ReflectionProperty::IS_PUBLIC, ReflectionProperty::IS_PROTECTED, or ReflectionProperty::IS_PRIVATE as a way to limit the returned properties. Flags may be combined by adding them together.
Example:
<?php
class Foo {
public $alpha = 1;
protected $beta = 2;
private $gamma = 3;
public function listProperties() {
$reflect = new ReflectionObject($this);
foreach ($reflect->getProperties(ReflectionProperty::IS_PUBLIC + ReflectionProperty::IS_PROTECTED) as $prop) {
print $prop->getName() . "\n";
}
}
}
$foo = new Foo();
$foo->listProperties();
?>
will output:
alpha
beta

It should be noted that the 'filter' parameter in the getProperties(filter) method is expected to be of type long. Not sure why, but it doesn't function as a way of passing in a string to fetch a subset of properties by string match.

With PHP 5.3 protected or private properties are easy to access with setAccessible(). However, it's sometimes needed (e.g. Unit Tests) and here is a workaround for getValue():
<?php
$class = new ReflectionClass('SomeClass');
$props = $class->getProperties();
// $propsStatic = $class->getStaticProperties();
$myPrivatePropertyValue = $props['aPrivateProperty'];
?>
Note that it wont work if you access the property directly with getProperty().
