Check if a function exists in specific file?

I would like to check if the $this->_controller function foo exist before I call it.

Example of call:

call_user_func_array([$this->_controller, $this->_url[1]]);

This will call the function url[1] in the controller inserted in the URL so, basically:

webserver/backend/foo

I want check if foo actually exists in the back-end.

How can I do this?

There are functions for most things. Check method_exists():

if(method_exists($this->_controller, $this->_url[1])) {
    call_user_func_array([$this->_controller, $this->_url[1]]);
}

For other uses see is_callable().
