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. -AZ > -----Original Message----- > From: Andi Gutmans [mailto:[EMAIL PROTECTED]] > Sent: Saturday, December 15, 2001 1:34 PM > To: August Zajonc; [EMAIL PROTECTED] > Subject: Re: [PHP-DEV] Unbuffered fgetc needed for stdin > > > This usually depends on how you configured your tty.
