PHP version: 5.4.6
Package: Sockets related
Bug Type: Bug
Bug description:MCAST_JOIN_GROUP on OSX is broken
Description:
------------
The multicast support in PHP 5.4 makes use of MCAST_JOIN_GROUP if it is
present.
The problem is that OSX 10.7 added the constant, but did not correctly
implement
the feature. This causes the setsockopt call to fail.
The solution to the problem is to not use MCAST_JOIN_GROUP on OSX.
Test script:
---------------
<?php
if (!extension_loaded('sockets')) {
die('skip sockets extension not available.');
}
if (PHP_OS !== 'Darwin') {
die('is not OSX.');
}
$socket = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);
socket_bind($socket, '0.0.0.0', 31057);
$so = socket_set_option($socket, IPPROTO_IP, MCAST_JOIN_GROUP, array(
"group" => '224.0.0.251',
"interface" => 0,
));
var_dump($so);
Expected result:
----------------
bool(true)
Actual result:
--------------
PHP Warning: socket_set_option(): unable to set socket option [22]:
