I’m trying to loop through an array of data

http://pastebin.com/MfJ8scTT

and if the dates are differnt then print the date for the specified week. The code I have works for checking the time against itself, but runs into issues checking the date.

$data = simplexml_load_file("http://api.XXX.com/ffnScheduleXML.php?apiKey={getYourOwnKey:)}");
    $gameDate = 1;
    $gameTime = 1;
    $gameDateTest = 0;
    $gameTimeTest = 0;
   
    foreach($data->Schedule->Game as $game)
    {

        if($game->attributes()->Week == $_GET['week'])
        {
           
            if($gameDateTest == $gameDate)
            {
                echo "\r";
            }else{
                echo "[COLOR=RED][B][U]".date('l, F jS', strtotime($game->attributes()->GameDate))."[/U][/B][/COLOR] : \$gameDate (".$gameDate.") | \$gameDateTest (".$gameDateTest.") \r\n";
            }

            if ($gameTimeTest==$gameTime)
            {   
                echo "\r";
            }else{
                date_default_timezone_set ("America/New_York");
                echo'[color=darkorange][size=3]'.date("g:i A",strtotime($gameTime)).' ET / ';
                date_default_timezone_set ("GMT");
                echo date("H:i",strtotime($gameTime)).' GMT / ';
                date_default_timezone_set ("Europe/Berlin");
                echo date("H:i",strtotime($gameTime))." CET[/size][/color]\r\n";   
            } 
            $gameTimeTest = $gameTime;
            $gameDateTest = $gameDate;
           
            $gameDate = $game->attributes()->GameDate;
            $gameTime = $game->attributes()->GameDate.' '.$game->attributes()->GameTime;
           
            echo  $game->attributes()->AwayTeam." at ".$game->attributes()->HomeTeam."\r\n";
        } 
    }

Any assistance in finding a solution would be greatly helpful.
