Logout class method fails to logout need help

[ppowell]

class LoginSessionGenerator extends MethodGenerator {

  function LoginSessionGenerator() {}

/**
 * Logout
 * 
 * @access public
 */
function &logout() {									// STATIC VOID METHOD
	global $projectFolderName, $projectURLPath, $willAuthenticate, $projectAcronym;
	if ($willAuthenticate) setcookie("$projectFolderName", '', time() - 86400);							// DELETE COOKIE
	foreach ($_SESSION as $key => $val) {
	 if (preg_match("/^${projectAcronym}_/i", $key)) unset($_SESSION[$key]); 						// DELETE ALL PROJECT SESSION VARIABLES
	}
	header('Location: [url]http://[/url]' . $_SERVER['SERVER_NAME'] . "$projectURLPath/index.php");			// DEFAULT REDIRECT TO MAIN PAGE
}

}

....

if ($_REQUEST['willLogout']) 
 LoginSessionGenerator::logout();

For some wacko reason, this class method does absolutely nothing except redirect. The cookie and session remains intact and unchanged, even the instance is intact and unchanged.

Could someone help me with this one?

Thanx

setcookie("$projectFolderName", '', time() - 86400, '/'); // IT COULDN'T **FIND** THE COOKIE!!!!

However, the session variables will not be unset, what must I do to destroy only CERTAIN session variables?

I freakin' give up. Someone tell me how to do this better, I can't figure it out after nearly 8 hours:

	/**
	 * Logout
	 * 
	 * @access public
	 * @return mixed HTML (returns HTML only if header() fails)
	 */
	function &logout() {									// STATIC VOID OR HTML STRING METHOD
		global $projectFolderName, $projectURLPath, $willAuthenticate, $projectAcronym, $phpVersionInt;
		if ($willAuthenticate) setcookie("$projectFolderName", '', time() - 86400, '/');							// DELETE COOKIE
		foreach ($_SESSION as $key => $val) {
		 if (preg_match("/^{$projectAcronym}_/i", $key)) {
		  $_SESSION[$key] = '';
		  unset($_SESSION[$key]); 						// DELETE ALL PROJECT SESSION VARIABLES
		 }
		}
		global $_SESSION;
		@flush();
		if ((int)$phpVersionInt > 420) @ob_flush();	// YOU CAN ONLY FLUSH OUTPUT BUFFER IN PHP VERSIONS 4.2+
		clearstatcache();
		header('Location: [url]http://[/url]' . $_SERVER['SERVER_NAME'] . "$projectURLPath/index.php");			// DEFAULT REDIRECT TO MAIN PAGE
		$html .= "\n<script type=\"text/javascript\">\n<!--\nlocation.href = 'http://" . $_SERVER['SERVER_NAME'] . "$projectURLPath/index.php';\n//-->\n" .
				"</script>\n<noscript>\n <meta http-equiv=\"Refresh\" contents=\"0;URL=http://" . $_SERVER['SERVER_NAME'] . 
				"$projectURLPath/index.php\">\n</noscript>\n";
		return $html;
	}
