PHP string concatenation
<p>The code below didn't concat the strings for me, how come ?</p>

<pre><code>$test = $this-&gt;address . $this-&gt;url;

echo $test; // prints the content of $this-&gt;address only
</code></pre>

<p>But this code works:</p>

<pre><code>$begin = $this-&gt;address;
$end = $this-&gt;url;
$test = $begin.$end;

echo $test; // prints the concatenation  
</code></pre>

<p>What am I missing?</p>
