Why are we using a string version of the code?

In the array_walk function we are using a string version of the function as a parameter. Why are we doing that?

array_walk($names, 'print_info');

We're using the name of the callback function as a string because that's what the PHP developers decided we should use. If you look at the examples in the documentation, you can see them showing you how to use the function.
