Doh... That's right. Stream input is usually buffered. Futzing with tty is
pretty ugly I think (stty/ioctl)...
On further reflection it seems that the getting a wrapper for ncurses or cdk
would be a real nice win for PHP. Perl's got a cdk module, think Python has
a ncurses wrapper. If they have reasonable license terms might be easy to
use those as a starting point for a php wrapper.
Wrapping these ncurses / cdk would be a nice add for PHP on the commandline.
Unfortunatly don't have the time to attempt something like this.

Subject: Re: [PHP-DEV] Unbuffered fgetc needed for stdin
This usually depends on how you configured your tty. I think by
default it
is buffered by the OS until a newline so it's probably not PHP
which needs
changing but your settings.

I've really run into a wall trying to get single charachters from stdin.
Something similar to the getchar macro or a real fgetc would be nice.
The current behavior is that more than a signle charachter can
be typed and
fgetc only returns when it sees a \n.
I'd like it to return immediatly after the first charachter.
fscanf with a format string something like %c requires a \n before
returning as well, though I suppose that is more understandable.
various things like fread with length of 1 also don't work.
This is missing functionality for which there is no workaround that would
certainly make shell scripting easier. It should be relativly trivial to
implement, either an unbuffered fgetc option or a new function
or something.
