ReflectionClass::getStaticProperties

I had the need to recursive merge the results from a subclass with all of it's parents, and this was the resulting code:
<?php
function GetStaticPropertiesRecursive($class) {
 $currentClass = $class;
 $joinedProperties = array();
 do {
 $reflection = new ReflectionClass($class);
 $staticProperties = $reflection->getStaticProperties();
 foreach ($staticProperties as $name => $value) {
 if (is_array($value)) {
 if (isset($joinedProperties[$name]))
 $joinedProperties[$name] = array_merge($value, $joinedProperties[$name]);
 else
 $joinedProperties[$name] = $value;
 } else {
 if (isset($joinedProperties[$name]))
 $joinedProperties[$name][] = $value;
 else
 $joinedProperties[$name] = array($value);
 }
 }
 } while ($class = get_parent_class($class));
 return $joinedProperties;
}
Using this function:
class base {
 public static $Test = array("foo1", "foo2");
}
class sub extends base {
 public static $Test = "sub";
}
print_r(GetStaticPropertiesRecursive("sub"));
?>

That outputs:
Array
(
 [Test] => Array
 (
 [0] => foo1
 [1] => foo2
 [2] => sub
 )
)
The merge follows the rules of array_merge on duplicate keys.

getStaticProperties return a set of the property itself. It's diferente from getProperties(ReflectionProperty::IS_STATIC) because it return a set of ReflectionProperty class.
