phpcomplete在建议中显示受保护的函数和变量

I installed phpcomplete and YouCompleteMe in vim. YCM work well for class functions and variable but not show completion for any built in function. Then I install phpcomplete ( as i read it also provide support for built in function ) but it after installing it I am not getting what i want instead YCM start showing me Protected variables and functions in suggestion list.

So question is how to get support for built in function for PHP and avoid protected functions and vars.
