Reported By: ryan at ryanmills dot net
Status: Open
Bug Type: Streams related
Operating System: win32 only - Vista X64
PHP Version: 5.2.10
New Comment:
Actually, it still doesn't work on Linux either (5.2.11).
Yes, the actual fread is non-blocking. However, if you press any key,
it is NOT registered so you can't react to keystrokes.
The code:
<?php
stream_set_blocking(STDIN,FALSE);
while (1)
{
$x = fread(STDIN,1);
var_dump($x);
if ($x != "")
exit;
}
As expected with non-blocking, the fread doesn't hold up execution of
the program. However, if a key is hit (something comes in on STDIN),
the program should immediately exit. It doesn't - it just keeps on
going, and going, and going....

tested on linux and 32bit windows. Linux works, windows does not.

Description:
------------
I have read a number of past bug reports from 2002 to just a month or
two ago. Under windows it does not seem that you can make STDIN non
blocking.
Follow code from: http://bugs.php.net/bug.php?id=47893&edit=2
Tested on 5.2.9-2 and 5.2.10
Notes say it was fixed in CVS so I assume 5.2.10 would have had the
fix.
*NOTE php.ini changes

max_execution_time = 0 ; Maximum execution time of each script, in
seconds
max_input_time = 0 ; Maximum amount of time each script may spend
parsing request data
;max_input_nesting_level = 64 ; Maximum input variable nesting level
memory_limit = 512M ; Maximum amount of memory a script may
consume (128MB)
Reproduce code:
---------------
<?php
stream_set_blocking(STDIN, FALSE);
while (1) {
var_dump(fread(STDIN,1));
echo "\n";;
}
?>
Expected result:
----------------
A never-ending sequence of var_dumps of either an empty string or a
typed character
Actual result:
--------------
stuck waiting for the user to press enter.
