Is this possible?

[10sion]

My site is on endless-anime.com and my forums is on ea-forums.com. I want my site to kinda be intergrated into the forums. But I need to tell if the users logged in, I already have the forums memberlist on my site but now I need to be able to be where you log in the forums it sets a cookie on both ea-forums.com (which it does) and endless-anime.com. Im not sure if setcookie can even do this, but I want to try, anyways I finally found vbsetcookie function and made some edits, although they dont seem to be setting the cookies on endless-anime.com anyone help?

// ###################### Start vbsetcookie #######################
function vbsetcookie($name, $value = '', $permanent = 1)
{
	global $vboptions, $_SERVER;

	if ($permanent)
	{
		$expire = TIMENOW + 60 * 60 * 24 * 365;
	}
	else
	{
		$expire = 0;
	}

	if ($_SERVER['SERVER_PORT'] == '443')
	{
		// we're using SSL
		$secure = 1;
	}
	else
	{
		$secure = 0;
	}

	$name = COOKIE_PREFIX . $name;

	$filename = 'N/A';
	$linenum = 0;

	if (!vbheaders_sent($filename, $linenum))
	{ // consider showing an error message if there not sent using above variables?
		if ($value == '' AND strlen($vboptions['cookiepath']) > 1 AND strpos($vboptions['cookiepath'], '/') !== false)
		{
			// this will attempt to unset the cookie at each directory up the path.
			// ie, cookiepath = /test/vb3/. These will be unset: /, /test, /test/, /test/vb3, /test/vb3/
			// This should hopefully prevent cookie conflicts when the cookie path is changed.
			$dirarray = explode('/', preg_replace('#/+$#', '', $vboptions['cookiepath']));
			$alldirs = '';
			foreach ($dirarray AS $thisdir)
			{
				$alldirs .= "$thisdir";
				if (!empty($thisdir))
				{ // try unsetting without the / at the end
					setcookie($name, $value, $expire, $alldirs, $vboptions['cookiedomain'], $secure);
					setcookie($name, $value, $expire, '', 'www.endless-anime.com', $secure);
				}
				$alldirs .= "/";
				setcookie($name, $value, $expire, $alldirs, $vboptions['cookiedomain'], $secure);
				setcookie($name, $value, $expire, '', 'www.endless-anime.com', $secure);
			}
		}
		else
		{
			setcookie($name, $value, $expire, $vboptions['cookiepath'], $vboptions['cookiedomain'], $secure);
			setcookie($name, $value, $expire, '', 'www.endless-anime.com', $secure);
		}
	}
	else if (!DB_QUERIES)
	{ //show some sort of error message
		global $templateassoc, $DB_site;
		if (empty($templateassoc))
		{
			// this is being called before templates have been cached, so just get the default one
			$template = $DB_site->query_first("
				SELECT templateid
				FROM " . TABLE_PREFIX . "template
				WHERE title = 'STANDARD_ERROR' AND styleid = -1
			");
			$templateassoc = array('STANDARD_ERROR' => $template['templateid']);
		}
		eval(print_standard_error('cant_set_cookies'));
	}
}

and the only part I really edited:

			foreach ($dirarray AS $thisdir)
			{
				$alldirs .= "$thisdir";
				if (!empty($thisdir))
				{ // try unsetting without the / at the end
					setcookie($name, $value, $expire, $alldirs, $vboptions['cookiedomain'], $secure);
					setcookie($name, $value, $expire, '', 'www.endless-anime.com', $secure);
				}
				$alldirs .= "/";
				setcookie($name, $value, $expire, $alldirs, $vboptions['cookiedomain'], $secure);
				setcookie($name, $value, $expire, '', 'www.endless-anime.com', $secure);
			}
		}
		else
		{
			setcookie($name, $value, $expire, $vboptions['cookiepath'], $vboptions['cookiedomain'], $secure);
			setcookie($name, $value, $expire, '', 'www.endless-anime.com', $secure);
		}
