To implement what you're after, use stream_select() and fread(); these work on stdin just fine. ------------------------------------------------------------------------ [2005-10-24 23:07:00] VJTD3 at VJTD3 dot com Description: ------------ STDIN won't allow nonblocking. Reproduce code: --------------- <?php stream_set_blocking(STDIN, FALSE); while (1) { echo 'infinate loop showing nonblocking problem'."\n"; echo 'said:'.fgets(STDIN, 1024); } ?> Expected result: ---------------- The test code should be a infinate loop with "infinate loop showing nonblocking problem" said trillions of times fast like a infinate loop is suposto do when you make a boo boo. instead it will say it once then wait for input then wait again etc as a blocked resource is expected. but "stream_set_blocking(STDIN, FALSE);" should be allowing it to do the loop unblocked resulting in major screen flooding yet unblocking the resource is ignored. This means you can't do something like a client program in your shell that is "interactive" like a Telnet client or similar. I can dig the whole not reading as typing because that would be too "raw" for common usage... [ie phrasing the backspaces etc though maybe a seperate abaility? this would allow arrow key kinda stuff and similar...] But waiting for a "\n" or whatever file ending shouldn't have any effect on that loop. It should act just like a TCP or any other connection when unblocked there the resource just has a return of no data. "php -f test.php" I use to run it. Actual result: -------------- uses blocking when "stream_set_blocking(STDIN, FALSE);" was used. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=34972&edit=1
