Well, there are several options here.
One option is to just build a password-protected web page on the other
server that does the exec() (or readfile for cpuinfo). Then you can
have PHP on server A do file_get_contents on the URL, if
allow_url_fopen is "ON"
Depending on how complex the target command is, you could also look
into running WebServices such as SOAP, RPC, REST, etc.
A valuable source of this kind of thing is from the zillion "control
panels" for webhosting that are "out there"
I think you might maybe be able to tunnel a command through SSH as a
one-off, but perhaps I'm just dreaming I read about that in man ssh a
few months ago.
To a large degree, HOW you do this depends much more on what commands
you want to allow, and even more importantly, disallow, than on
anything involving PHP. In fact, PHP itself is only a
thinly-disguised wrapper for whatever you will come up with. So
you're better off asking about this kind of thing on an OS or Linux
distribution mailing list, probably. The PHP bit will end up just
being <?php exec("$something")?> no matter how you look at it.
