Change index.php as follows:

<?php
  include "function.php";
  myCustomFunction();
?>

(this is based on the assumption that both files are in the same directory, otherwise you have to add the filepath in the include line)

You just need to include the other file:

include('function.php');

index.php:

<?php

include('function.php');

myCustomFunction();

The include function in PHP inserts in-place the code contained in the file passed to its parameter.

For further details, and alternative, please refer to PHP manual:
