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 to post it here, but I would suspect that one
of the problems in doing a telnet client in php is that the telnet client
needs to be multi-threaded. Perhaps someone will someday take open source
like Dave's Telnet and fashion an extension to PHP.
Til then, try the options above,
Warren Vail

Subject: [PHP] Telnet and PHP
I was doing some research on creating a webbased telnet client and I am
unsatisfied with Java applets. I would like to create a server side telnet
client, so the user side is only required to have a working web browser that
supports HTML.
Thus, I turned to PHP. I found one example, but it does not allow for active
user input. While I will sit down this evening and work with the code, I was
wondering if anyone had/knew of a good example of a PHP telnet client.
