How to interpret this PHP statement?
<p>I would like to know what kind of variable is <code>$firstLine</code> in the following php code line. Is it a pointer or what ?    </p>

<pre><code>$firstLine=$myMovie-&gt;add($myShape1);
</code></pre>

<p>Thanks</p>

<p>OK here is the complete code:</p>

<pre><code>  &lt;html&gt;
 &lt;body&gt;
  &lt;? 
   $myShape1=new SWFShape(); 

   $myShape1-&gt;setLine(5,0,0,255); 

    $myShape1-&gt;drawLine(440,0); 

   $myMovie=new SWFMovie(); 

   $myMovie-&gt;setDimension(460,80); 
   $myMovie-&gt;setBackground(255,0,0); 

   $firstLine=$myMovie-&gt;add($myShape1); 
   $firstLine-&gt;moveTo(10,10); 

    $secondLine=$myMovie-&gt;add($myShape1); 
   $secondLine-&gt;moveTo(10,70); 

   $myMovie-&gt;save("lesson2.swf"); 

  ?&gt; 

   &lt;OBJECT classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"    codebase="http://active.macromedia.com/flash2/cabs/swflash.cab#version=4,0,0,0" ID=objects        WIDTH=460 HEIGHT=80&gt;
   &lt;PARAM NAME=movie VALUE="lesson2.swf"&gt;

</code></pre>
