ID: 19944 Comment by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] Status: Feedback Bug Type: Sockets related Operating System: RedHat 7.3 PHP Version: 4.3.0-pre1 New Comment:
As of snap-200210181500 it still doesn't work. Results are the same with garbage returned when using fgets() on STDIN when in non-blocking mode. Last two snaps I've tried (10/17 and 200210181500) have the added feature of also core dumping when fgets() is used on a non-blocking socket opened with fsockopen(). Previous versions of PHP work as expected with fgets() on a non-blocking socket, but the snaps seem to core dump. 10/17 snap would core dump on first call to fgets() whereas today's snap seems to go through the while loop three times and then core dumps when it hits fgets() again. Thus, the current observation is that when using fgets in non-blocking mode: 1. STDIN returns garbage. 2. Sockets core dump.

Also, you should use if ($string !== false) to 100% correct in your script. ------------------------------------------------------------------------ [2002-10-17 17:07:37] [EMAIL PROTECTED] Try this one again: http://snaps.php.net/php4-latest.tar.bz2 You might have got the snapshot which didn't have the fixes. ------------------------------------------------------------------------ [2002-10-17 12:52:36] [EMAIL PROTECTED] I just tried with the latest from snaps.php.net. Problem still exists as of php4-200210170600. ------------------------------------------------------------------------ [2002-10-17 02:15:13] [EMAIL PROTECTED] This bug has been fixed in CVS. In case this was a PHP problem, snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. In case this was a documentation problem, the fix will show up soon at http://www.php.net/manual/. In case this was a PHP.net website problem, the change will show up on the PHP.net site and on the mirror sites in short time. Thank you for the report, and for helping us make PHP better. Use a snapshot from http://snaps.php.net/php4-latest.tar.bz2 fgets had some real nasty problems. ------------------------------------------------------------------------ [2002-10-16 23:32:19] [EMAIL PROTECTED] I am trying to use the CLI version of 4.3.0-pre1. My script needs to act if there hasn't been input within a certain amount of time. I've used the following function to accomplish this with TCP/IPsockets in non-blocking mode: function GetSocketLine($socket, $timeout) { $timeout += time(); $holdString = ""; while(time() < $timeout) { $string = fgets($socket, 1024); if($string != false) break; } return($string); } However, if I use set_stream_blocking() to set STDIN to non-blocking, the above code returns garbage instead of "false" when there is nothing to receive. It would seem to me that if STDIN is set to non-blocking and STDIN is passed to the above function as $socket, it ought to return "false" when blocking would occur--it shouldn't return garbage. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=19944&edit=1
