PHP fsockopen 400 Bad Request

I have this strange problem that I'm receiving 400 Bad request as a response and I have absolutely no idea what's wrong with the header. Here's my code:

<?php

$sock = fsockopen('IP ADDRESS', 80, $errno, $errstr);

$header = array(
    'GET / HTTP/1.1',
    'Host: stackoverflow.com',
    'User-agent: My Useragent',
    'Connection: Close'
);

fputs($sock, join('\r\n', $header));

while(!feof($sock))
{
    echo fgets($sock, 128);
    break;
}

fclose($sock);

?>

Any ideas what I'm doing wrong?

Thanks

EDIT: Thanks to MrCode this problem was solved. Issue was here:

fputs($sock, join('\r\n', $header));

I had to change it to:

fputs($sock, join("\r\n", $header)."\r\n\r\n");

Notice double quotes and "\r\n\r\n"

Thanks again to MrCode

You're missing \r\n\r\n which is required after the final header. Currently you have nothing after the final header.

Append it to the join result:

fputs($sock, join("\r\n", $header) . "\r\n\r\n");

Also, you need to use double quotes around the \r\n because using single quotes causes PHP to take it literally and not as a new line.
