Where does PHP define an empty function in PHP source code?

I'm going through the PHP source code I found on my GitHub and I just can't figure out where it is that they define an empty function. Now this leads me to believe they are passing this through internal C functions, but I don't know enough about the design, but I'm not sure.

I am curious to know where the empty function is defined in the PHP source code.
