socket_bind creates file in /tmp, but www-data has no permissions to it

[fearr1]

Server.php -> openIPCSocket() -> socket_bind -> creates a file in /tmp but www-data has no permissions to use it. This happened when i tried to send IPC data from an action of a website to the WebSocket server. This change did the trick:

FROM
if (socket_bind($this->icpSocket, $ipcSocketPath) === false) {
throw new \RuntimeException('Could not bind to ipc socket.');
}

TO
if (socket_bind($this->icpSocket, $ipcSocketPath) === false) {
throw new \RuntimeException('Could not bind to ipc socket.');
} else {
chown($ipcSocketPath, 'www-data');
}

I added a fix for this. It is now possible to set user/group and mode for the IPC file:

$server = new \Bloatless\WebSocket\Server('127.0.0.1', 8000, '/tmp/phpwss.sock');
$server->setIPCOwner('foo');
$server->setIPCGroup('www-data');
$server->setIPCMode(0755);

Keep in mind that the user you start the server with needs to be in the desired group for this to work.
