[PHP] Re: talking to a web page
You can use PEAR's HTTP_Client package
(http://pear.php.net/package/HTTP_Client) to connect to a website, do
authentication, post forms, handle redirects, etc. It also keeps track
of cookies.
Here's a sample (note that the URLs in this will probably not work):
require_once('HTTP/Client.php');
$client = new HTTP_Client(array('user' = 'username', 'password' =
'password'));
$code = $client-post('http://www.example.com/script.asp',
array('var1' = 'val1',
'VAR2' = 'val2'));
$code = $client-get('http://www.example.com/loginRequired.php');

Hi, all --
My host has written a control panel to handle all site management needs,
and it's great except that there's no back-end hook that I can use to
create a new site or user once I have collected my input and verified my
payment in my own pages. I obviously don't want to have to do all of the
site creations by hand; that's why we have computers :-)
At this point I could either figure out all of the steps for creating a
site -- there are, to my knowledge so far, DB tables to update, dirs to
make, other files to update, and apache to restart -- or figure out how
to talk to the control panel from a script. With nearly fifteen years of
SysAdmin background but only a few years of PHP background, I know which
I think is probably easier or at least quicker :-) but I don't want to
miss any little things that their interface does that will bite me in the
tail later.
The control panel requires authentication and a cookie and then a few
clicks to get to the fill-ins, so I imagine that I could just construct
that form and hand it off -- except for the login authentication part.
Which route would y'all take, and (more importantly) which would you
recommend to someone at my capable-but-not-expert level? Remember that
I'll come back to the list when I get stumped ;-)

OK, so I don't actually need to navigate the page but instead just fill
in the fields and then send it. Very cool.

Now to figure out how to try it out :-)

Re: [PHP] Re: talking to a web page
One last thing. If all you need to do is go to a page and not navigate
it, you could just use HTTP_Request, upon which HTTP_Client is built.
Then again, if you have multiple request to do and have to keep sending
the auth data, the Client would be best.

That sounds even better; I'm only going to be dealing with a couple of
pages.

I'll try either both. I'm having some trouble getting started, though...
I surfed over to pear.php.net, found and downloaded both (yikes, Client
is only a 0.2 release :-) and opened them up. I made
/usr/local/lib/php/HTTP
and then copied each's contents in there (well, the docs/ over to the lib
docs file), so I now have
/usrlocal/lib/php/HTTP/Client.php
/usrlocal/lib/php/HTTP/Client/CookieManager.php
/usrlocal/lib/php/HTTP/Client/Listener.php
and similar for HTTP_Request but when I run a simple
echo ?php require_once('HTTP/Client.php') ; print 'done';? |php -q
I get back Failed opening required 'HTTP/Client.php' :-(
Is there a different install procedure?

Re: [PHP] Re: talking to a web page
Well, technically, you should be using the PEAR installer script to
install PEAR packages. http://pear.php.net/manual/en/installation.php
Barring that, you can make yourself a PEAR directory somewhere and add
it to your include_path in your php.ini.
Also note that you have to have all of the dependencies for those
packages. Easiest way to go is to use the PEAR installer if you're just
getting started.
