What does it mean when something uses two -> operators in php?
<p>I'm looking at some code here and there are bunch of calls that are like this. I don't have much experience with php, mainly java. Is this like if I had a Dog object that had a fur object and I wanted to call "dog.getFur().getColor();" ?</p>

<p>Example:</p>

<pre><code>  $this-&gt;tbtemp_list1-&gt;lead_time = ($this-&gt;add_lead_time-&gt;Text + $this-&gt;add_transit_time-&gt;Text);
  $this-&gt;tbtemp_list1-&gt;units = $this-&gt;add_units-&gt;Text;
  $this-&gt;tbtemp_list1-&gt;item_class = $this-&gt;txtClass-&gt;Value;
  $this-&gt;tbtemp_list1-&gt;category = $this-&gt;add_part_category-&gt;Text;
  $this-&gt;tbtemp_list1-&gt;description = $this-&gt;add_part_description-&gt;Text;
  $this-&gt;tbtemp_list1-&gt;notes = $this-&gt;txtNotes-&gt;Text;
</code></pre>
