Description:
------------
When trying to listen on a udp socket in freebsd with php5, php fails to create the socket and returns unknown error.

The manual page gives an example about a udp server, however this returns the same error.

Operating system (uname -a):

FreeBSD 5.1-RELEASE #0: Thu Jun  5 02:55:42 GMT 2003     root@wv1u.btc.adaptec.com:/usr/obj/usr/src/sys/GENERIC

PHP version (php -v):

PHP 5.0.0RC1-dev (cli) (built: Jan 16 2004 22:47:26)
Copyright (c) 1997-2004 The PHP Group
Zend Engine v2.0.0-dev, Copyright (c) 1998-2004 Zend Technologies

PHP configure line:
./configure --with-mysql=/usr/local/mysql --with-mime-magic --with-apxs=/usr/local/sbin/apxs --enable-wddx --with-zlib --enable-bcmath --with-bz2 --with-ncurses --enable-cli --disable-cgi --with-gd --with-jpeg-dir --with-png-dir --with-zlib-dir --with-calender --enable-pcntl --enable-sysvsem --enable-sysvshm --enable-sysvmsg --enable-exif --enable-sockets --with-xpm-dir --with-gettext --with-gmp --enable-mbstring --with-xmlrpc --with-xsl --with-ex --enable-openssl

Reproduce code:
---------------
<?php
$sock = stream_socket_server('udp://0.0.0.0:27961');
?>

Expected result:
----------------
No output

Actual result:
--------------
Warning: stream_socket_server(): unable to connect to udp://0.0.0.0:27961 (Unknown error) in /share/wolfd/serv.php on line 2

The port is open, and I run this script as root

root@glox /share/wolfd# sockstat | grep 27961
root@glox /share/wolfd#

Please try using this CVS snapshot:

  http://snaps.php.net/php5-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php5-win32-latest.zip

Seems to work for me.

udp:// sockets should not attempt to listen().  Because stream_socket_server() uses both the bind and listen flags by default you need to explicitly set them to bind only.

I've fixed the example to reflect this.

Isn't it better to let php define those flags then, based on the socket type (udp/tcp).

I don't see any change in the example either ...

It'd be nice, but because of the way the transports layer operates it won't happen without making exceptions on a per protocol basis and that's gernerally not a good idea.

As to the documentation, the source has been updated, but the online manual is only rebuilt from source on a periodic basis.

The change amounts to:

$server = stream_socket_server('udp://0.0.0.0:13/', $errno, $errstr, STREAM_SERVER_BIND);
