The code formatting options for PHP syntax do not work for class members.

Options->Editor->Formatting

Language: PHP
Category: Blank Lines

1. The option "Before Field" does only apply to the first declared field
2. "After Field" seems to be completely ignored.

So 

class Test
{
    protected $field1;

    protected $field2;

    protected $field3;
}

becomes after formatting:

class Test
{
    protected $field1;
    protected $field2;
    protected $field3;
}


even if there is a value > 0 in "After Field"

I tested this in the Java Editor and it seems to work fine with Java Classes.
