<?php
# Make life easier to test bothe versions

# note for php4 or lower:
# STDIN isn't a defined "constant" so uncomment this.
#define('STDIN', fopen('php://stdin', 'r'));
# ment to paste fread was playing with other methods and
# just pasted the wrong version. The result is the same.

# same code with fread and blocked reguardless of setting
# to nonblocked.

# stream_select() can't be used, when i try the file
# descriptor just gets locks and all future selects won't
# work. and there is no reason to even select i know what
# resource to monitor i just need blocking to stop so i
# can monitor and process as i need just liek in the
# yahoo http example.

FYI, using fgets() with a non-blocking resource makes no sense.
To implement what you're after, use stream_select() and fread(); these
work on stdin just fine.

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.
