Where To Add The Fake Referer, etc ?

Php Gurus,

Look at this Mini Proxy Gpl:
https://github.com/joshdick/miniProxy

I need to add my own php code to:

As you can see, the MiniProxy is a simple Web Proxy.
It does not view https pages.
It does not fake the Referer.
It does not log the fetched page onto your mysql db.

Now, let us change all this.
And so,
Q1. On which numbered line to add php code to enable the web proxy to view https/ssl pages ?
Q2. On which numbered line to add php code to add a Fake Referer ?
Q3. On which numbered line to add php code to dump the browsed url to mysql db ?

Remember, here I am not asking you for php code to enable https page views. Just asking on which line to add it.
And remember, here I am not asking you for php code to fake the referer. Just asking on which line to add it.
Do remember, here I am not asking you for php code to dump the visited url to mysql db. (I know how to write that code). Just asking on which line to add it.

The one page php script is here:
https://github.com/joshdick/miniProxy/blob/master/miniProxy.php

I need you to point me in the write directions in terms of line numbers. That is all.
