#34972 [Com]: STDIN won't allow nonblocking.

ID: 34972 Comment by: julian at precisium dot com dot au Reported By: VJTD3 at VJTD3 dot com Status: Open Bug Type: Streams related Operating System: * PHP Version: php5.1-200603270630 Assigned To: wez New Comment: I'm having this problem on Vista x64 with PHP 5.2.3. This is a real showstopper for certain types of CLI app - people can't always be waiting for newlines or eofs to read their data. I don't mean to be rude but I'm kinda shocked such a major bug has been unaddressed for nearly 2 years. I guess it just means people aren't really using PHP for CLI apps on the windows platform.

It works on my linux systems however. ------------------------------------------------------------------------ [2007-08-10 13:01:48] VJTD3 at VJTD3 dot com <?php stream_set_blocking(STDIN, FALSE); echo fread(STDIN, 10); ?> notice how it just sits there? (blocking) it should exit instantly with a null echo. (same as a tcp connection where if you just do a read that is too fast with nonblocking it never gets a chance to fetch the data.) what is happening is that php is blocking waiting for input (specifically enter (line ending)) problem: if you are echoing debug information and want to use key functionality in tandem you can't because everything is blocked till you hit enter. ------------------------------------------------------------------------ [2007-07-25 01:00:00] php-bugs at lists dot php dot net No feedback was provided for this bug for over a week, so it is being suspended automatically.
