PHP header function not triggering?

Question

I'm getting some fairly odd behavior here... I noticed that only localhost, a header statement I have worked just fine, but when copied over (SAME EXACT CODE) to my live site, the header statement no longer triggers.

I added some echos to help debug. This if statement will only trigger if the URL variable id is NOT set. So with this same exact code on localhost, I never see these debug statements. On the live site, I do... which I shouldn't. I should get redirected instead. Anyone know why a header statement would be ignored?

if((!isset($_GET['id'])) && $rows != 0) {
      $result = mysql_query('SELECT videoinfo FROM videos where game_id=' . $gameid . ' LIMIT 1');
      $row = mysql_fetch_array($result);
      $tubeID = $row['videoinfo'];
      echo '<script type="text/javascript">';
        echo 'window.location = "videos.php?id=' . $tubeID . '&awayid=' . $awayid . '&homeid=' . $homeid . '&date=' . $date . '&time=' . $time . '&gameid=' . $gameid . '&play=0"';
      echo '</script>';
}

EDIT 4 people have told me already that I can't have any echo calls before my header function. This code WORKS on localhost and the header function DOES trigger. Regardless, REMOVING the echo statements DOES NOT fix it.

Answer 1

AFAIK

Can't send header() after some echo.
