如何防止null在Internet Explorer中显示？

Question

The following is a section of my php page where I am displaying a variable based on weather or not it has a value. This works fine in Firefox and Chrome but in internet explorer "null" is being displayed when the variables have no value rather than just being blank like in FF or Chrome. Is there a way to fix this?

<tr>
 <td>Track</td>
 <td><?php echo $trackResult. '&acute;<br/>';
    if($trackResultOne != NULL){ echo $trackResultOne."&acute;<br/>";}
    if($trackResultTwo != NULL){ echo $trackResultTwo."&acute;";}
    ?></td>
</tr>

Unfortunatelly, you will need to use the ELSE part of the IF to retrieve a blank (''), IE converts automatically the real null into the string 'null'.
