I have a function which echoes javascript to navigate to a different page. While navigation occurs, the

echo 'window.location.href='.$url.';'; 

does not work and simply prints it on the screen.

window.location.href=./index.php;

I use my function this way: redirect(./index.php);

My php function is as follows

  function redirect($url)

   {    

    if (!headers_sent())

    {    

      header('Location: '.$url);

      exit;

    }

   else

    {      

      echo '<script type=text/javascript>';

      echo 'window.location.href='.$url.';';

      echo '</script>';

      echo '<noscript>';

      echo '<meta http-equiv=refresh content=0;url='.$url.' />';

      echo '</noscript>'; exit;

   }

}
