If you just do something like:
ssh hostname
Then ssh will try and establish a terminal connection. If you're
trying to do a command of some sort it will be:
ssh hostname command
Then of course you'll need to somehow authenticate.. you can google
'man ssh' to find out how to use ssh if you don't have shell access
to the machine.

Yes, there is a ssh2 library available for php, it is currently in
beta release, but from my experience it is quite stable to use.
PECL Extension:
http://pecl.php.net/ssh2
Documentation:
http://php.net/ssh2
