Set cookie function - part of old codebase.

setCookie.php

function setCookieVariable($cookieName, $value, $secureOnly = false){
    $timeSeconds = 60 * 60 * 24 * 30; //30 days in the future.

//	if($GLOBALS['outputStarted'] == true){
//		logToFileFatal("Trying to set cookie '$cookieName' but page output has already started. That's bad.");
//		header('X-OUTPUT-STARTED: 12345');
//		return;
//	}

	if($secureOnly == true){
		if(isHTTPSPage() == false){
			logToFileFatal("Setting Cookie [$cookieName] which is meant to be a secure cookie.");
		}
	}

	$domainInfo = DomainManagement::getDomainInfo();
	$domainForCookie = '.'.$domainInfo['rootCanonicalDomain']; //leading dot according to http://www.faqs.org/rfcs/rfc2109.html

	if($value === null){
		logToFileFatal("Trying to set cookie $cookieName to be NULL. Please use unsetCookie to do this, to avoid cookies being accidentally deleted.");
	}

	if($secureOnly == true){
		setcookie($cookieName, $value, time() + $timeSeconds, '/', $domainForCookie, true,  true);	//We need to set the root domain explicitly
	}
	else{
		setcookie($cookieName, $value, time() + $timeSeconds, '/', $domainForCookie); //We need to set the root domain explicitly
	}

	//we also set the $_COOKIE variable so that reading the cookie read the same value on this page as subsequent pages.
	$_COOKIE[$cookieName] = $value;
