i test fclose() method ,but TCP connection still on TIME_WAIT status.


Test script:
---------------
==========================
method one
==========================

function connectRedis($host, $port){
	$host = 'tcp://' . $host . ':' . $port;
        $socket = @stream_socket_client(
            $host,
            $errorNumber,
            $errorDescription,
            ini_get("default_socket_timeout")
        );
	//stream_socket_shutdown($socket, STREAM_SHUT_RDWR);
        fclose($socket);
}

$host = '192.168.2.243';
$port = 7000;

for($i=0; $i<100; $i++){
    connectRedis($host, $port);
}


==========================
method two
==========================

function connectRedis($host, $port){
	$host = 'tcp://' . $host . ':' . $port;
        $socket = @stream_socket_client(
            $host,
            $errorNumber,
            $errorDescription,
            ini_get("default_socket_timeout")
        );
	stream_socket_shutdown($socket, STREAM_SHUT_RDWR);
        fclose($socket);
}

$host = '192.168.2.243';
$port = 7000;

for($i=0; $i<100; $i++){
    connectRedis($host, $port);
}



Expected result:
----------------
netstat -an |grep '192.168.2.243'

return :
