在类中调用函数函数(PHP)

Very simple setting, but I simply don't get it...

functions.php

class functions {
    function output_functions() {
        function sendMail($to, $subject, $message){
            //...code...
        }
    }
}

myfile.php

include $_SERVER['DOCUMENT_ROOT'] ."some/subfolders/functions.php";

$myFunction = new functions();
$myFunction->output_functions()->sendMail("mail@mail.com","My Subject","My Message");

And I'm getting the Error:

Call to a member function sendMail() on null

Any help will be highly appreciated!

    If you want to group your functions by type (output_functions, input_functions, whatever) I'd do a different class for each. You then should define them as public or private.

    As it already has been said, nested functions cannot be accesed from outside, they're just available inside the scope of the function in which they are defined.
