Description:
------------
ReflectionProperty::getDefaultValue() returns null only if the property is not static.

Reproduce code:
---------------
class test{
	public $test = 'aze';
	static $stat = 'ic';
}


$class = new ReflectionClass('test');
foreach($class->getProperties() as $k => $v){
    var_dump($v->getValue($class));
}

Expected result:
----------------
string 'aze' (length=3)

string 'ic' (length=2)


Actual result:
--------------
null

string 'ic' (length=2)

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Your code is wrong. The parameter to getValue has to be an instance of the reflected class, not the reflection object. Try

<?php
class test{
        public $test = 'aze';
        static $stat = 'ic';
}


$class = new ReflectionClass('test');
foreach($class->getProperties() as $k => $v){
    var_dump($v->getValue(new test()));
}
?>

instead.
