PHP pack() troubles (I will PayPal for expert help)

[raymor]

'm looking for someone who is very familar with PHP
pack and unpack() magic for help with a script I'm working on.
I wrote a Perl script to query an ntp (time) server and I
need to port it to PHP. I've got most of it, but using the
named parameters with unpack() is foreign to me and
I've got some long, complicated unpacking to do. Looking
at the docs and at my code makes my head swim.

Here's my original (working) Perl script:

Mostly ported to PHP, with a bit of work left:
