What are the potential reasons for the scrollbars not appearing in a popup window despite setting "scroll=yes" in PHP code?

The potential reasons for the scrollbars not appearing in a popup window despite setting "scroll=yes" in PHP code could be due to the size of the content not exceeding the size of the window, or the browser settings overriding the scrollbars. To ensure the scrollbars appear, you can set a fixed height and width for the popup window in addition to setting "scroll=yes". 

echo "<script type='text/javascript'>
        var popup = window.open('popup.html', 'Popup', 'width=400,height=400,scrollbars=yes');
        popup.focus();
      </script>";
