Jerry--you are a great teacher. And I do understand. I'm having my
usual problem of determining where to actually save my php files so
that they are in the local root folder. Whenever I type in local
host
and then browse it automatically resets me to C:\yahdiyahdi, etc.
I
don't think using install to programs folder is my best option. I'm
going back to read manual install and see if I gain some
enlightenment.
Please feel free to give me more pearls of wisdom. There was
nothing
confusing about that.
How many dogs?

Glad you got the installs for XAMPP completed. Thank you for
finding
the
control panel, my XAMPP install was before that was added so I added
it
now. That is helpful especially to see the little green running
labels.
You seem confused by the networking addresses. For any web site
there
are
many times two ways to reach it. First is the name such as
www.lehigh.edu
(a college by Bonny) and that is also at an IP address
of 128.180.2.14. If you go to a command box and type in C:\ping
www.simoogle.com (a tribute to by deceased dog) it will resolve to
216.52.184.240. Where http://128.180.2.14 will take you to Lehigh
University, http://216.52.184.240 will take you to a screen saying
that
"We're sorry, but we were unable to process the redirection request
for
the
site you are attempting to access. If you feel that you are
receiving
this
message in error, please check the URL and try your request again."
That
is because that page is being referred from one web hosting company
to
another and needs the name ID to properly identify it. The IP
216.52.184.240 actually goes to a hosting server at namecheap.com
All of this magic is done on the Internet with DNS (dynamic name
service).
Your webserver would need a DNS entry for outsiders to reach it by
name.
If
it had a static IP folks could reach it without a DNS entry if that
IP
was
entered. What happens however is that multiple websites are hosted
on a
single webserver so you need a name for that server to parse the
traffic
even if you can reach it by IP address only.
Now to "localhost." Your computer actually has 4 identities. Mine
has a
computer name, "Schuster." My computers are named after our
Weimaraners....Simon, Schuster, and Moose(the laptop). You probably
know
you computers name, if not it is available on the properties page
for My
Computer. By convention "localhost" is an alias and can be
substituted
for
the computer's name on any computer, but only on that same computer.
Similarly the local IP of my is 192.168.0.13 and can be found from
the
command prompt with "ipconfig." Again there is a shorthand alias
for
the
local IP of all computers so they can talk to themselves and that IP
is
127.0.0.1 If you start your Apache and see the little green running
light
you can enter any of the four address to get to the Apache splash
page:
http://127.0.0.1/xampp/splash.php
http://192.168.0.13/xampp/splash.php
http://schuster/xampp/splash.php
http://localhost/xampp/splash.php
Localhost and 127.0.0.1 allow programmers and controls to access the
webserver locally without knowing it's name or local IP. Just to
confuse
you further, there is a text file buried on your computer called
Hosts.
If
you put an entry there, you can point any name like
"www.simoogle.com"
to
any IP, including 127.0.0.1 so you could use the actual name to run
it
(only for you) on your test server without using any of the above
four
methods. Of course your could not reach the real external site
without
changing or deleting the host entry. Just as an aside, there is
also a
file lmhosts that allows you to associate your computer name with a
specific IP. This can be helpful or dangerous DAMHIK.
So if you didn't understand the localhost concept before, I'm sure
that
I
have totally confused you. But just type it in at the beginning of
the
address and it will keep it on your local webserver instead of
scouring
the
Internet for a different one. Hope that helps.
Jerry
