Simple question about IF statement
<p>I just wonder how to check if there is a value in a column in a database table? The column is named <code>star</code> and I want to check if it has a value of 1 if not don't do anything. </p>

<pre><code>while($row01 = $res01-&gt;fetch_object()) {

    if ($res01-&gt;star[$row01] == 1) { ??????????

    }

}
</code></pre>

<p>I use thise WHILE LOOP to fetch info from a table about some objects. For some objects I have a column named STAR that is 1 och NULL. While I build up the HTML-code into variables I in this loop, I also check if the object has 1 in the STAR column and if yes I create another variable with some HTML-code to use in the list of all the objects in the table.</p>

<p>But when I use  if($row01->star == '1') it's not working and I don't know why!? When I use this it's like, yes all objects has 1, but there is only a few that has 1, the rest has NULL value. Sorry, but I have to leave the computer for some houres, but I hope to solve this later today! Thanks!</p>
