    Calling this method on a static property that is not public will return a ReflectionException stating the property does not exist. This is quite misleading as the property is valid.

    class test {
    public static $publicProperty = 'public';
    private static $privateProperty = 'private';

    public static function printProperties() {
    echo self::$publicProperty . "\n";
    echo self::$privateProperty . "\n";
    }
    }

    $reflectedClass = new \ReflectionClass('test');
    $reflectedClass->setStaticPropertyValue('publicProperty', 'foo');
    $reflectedClass->setStaticPropertyValue( 'privateProperty', 'bar' );

    PHP Fatal error: Uncaught exception 'ReflectionException' with message 'Class test does not have a property named privateProperty'

    If you retrieve the method using the reflection class getProperty method you can circumnavigate this issue

    $reflectedProperty = $reflectedClass->getProperty('privateProperty');
    $reflectedProperty->setAccessible(true);
    $reflectedProperty = $reflectedProperty->setValue('bar');

    test::printProperties();
    will echo
    foo
    bar

    It is important to note that calling ReflectionClass::setStaticPropertyValue will not allow you to add new static properties to a class.
