Seperate results by change in first order by term

[Guernica]

Here's the query:

$sql = mysql_query("SELECT * FROM resources WHERE gameCat = '' ORDER BY systemCat,order_id");

 

I want something to happen when the systemCat changes in the results. Like this:

 

if($row['systemCat'] CHANGES){
echo '<div id="seperator"></div>';
}

 

Any ideas? Thank you!
