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

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.
