RE: [PHP] Telnet and PHP
Jon,
Looked like a nice solution, but couldn't get the code to work. Kept going
into an endless loop or wait state somewhere.
still forced to use rexec.

By active user input, I would assume that you mean every time the user
makes a keystroke, the keystroke is sent to the host machine. This is not
a
characteristic of html which only sends information to the host machine
when
some form of submit is clicked. The advantage of the applet for this sort
of thing is it runs on the browser client, and has the capability of
sending
every keystroke directly to the host, bypassing the server side.
On the server side, once the (PHP) application is done sending the
requested
files to the web browser for one user, it moves on to handling the
requests
for other users. Can you imagine the load on a server if it had to reload
your application every time, your user pressed a key.
You never really made it clear where you expected this client to run,
although PHP, at this point, can only run on the server. Now if you are
looking for something that your PHP code could use to 1. signon to a host
somewhere, 2. execute some commands, 3. capture and process the results
and
4. disconnect before completing a single page to a web browser client (it
will probably never do active user input, because of the nature of PHP
and
the web server), then I would suggest you consider rexec, rcp, rsh
or
if what you want is in a file on the host machine, you could use the ftp
functions. These are not telnet, and do require special deamons running
on
the host machine, but may do the trick.
I have been looking for your telnet client for a long time as well, and if
you find one, please remember

I found one example, but it does not allow for active user input.

there's fsockopen from which you might make a telnet client, methinks, but you'd have to know the protocol etc... look for it at the manual.
