If you want the input from the keyboard on the web-server machine (not the
client) you can use:
$file = fopen('php://input', 'r');
$char = fread($file, 1);
If you want keyboard input from a web browser client, you'll have to either:
Use JavaScript to capture the input, and then open up another HTTP
connection to a totally different PHP script to do something with it, or
Create a Java applet and Java servelet to have a keep-alive connection that
captures the browsers keystrokes and sends them back (via the Java servlet)
to PHP.
The first option will be dog-slow and completely un-usable for all but a
very limited class of solutions...
Keep in mind that PHP runs on the *SERVER*, and, in fact, your PHP script is
completely finished, dead, and gone by the time the user types a key.
If these options are unhelpful, tell us what you are actually trying to do
at a higher level.
Oh yeah: For purely server-side shell-scripting keyboard cool-ness, I would
imagine that the new GTK-PHP combination would have some nifty stuff in
it... Haven't even looked at it myself, and I don't even know GTK, so it
will be awhile before I can say anything more intelligent about it... Not
that that always stops me :-)
