Description:
------------
In relation to http://bugs.php.net/bug.php?id=46360 I think it would be useful 
to have the ability to set the TCP_NODELAY flag on socket streams. The arguments 
for this feature request are basically the same as of #6360, and it would 
greatly help with performances under certain circumstances when dealing with 
chatty network protocols.

The following snippet is an example of how the resulting code might look like in 
a PHP script:

$opts = array(
    'socket' => array(
        'tcp_nodelay' => false,
    ),
);
$stream = stream_socket_client($uri, $errno, $errstr, $timeout, $flags, $opts);


Cheers,
Daniele Alessandri

So.. I attached a patch, but I have not tested it (can't compile on this machine) and it's also the first time I touch PHP's sources, so given my little C experience it may very well be incorrect. But I wanted to show goodwill. Hopefully someone picks this up and implements this small feature.

So the attached patch should be good now, as you (johannes) said TCP_NODELAY is used without ifdef [1] already so it should be fine to use it as is.

Now if I could have php-src karma to commit it myself it'd make my day, but I guess that's not good enough :)

Thank you for the report, and for helping us make PHP better.

The stream context socket option tcp_nodelay => true will set SOL_TCP,NO_DELAY=1 appropriately.

Will be in 7.1
