What is @ in an object property?
<p>I have the following object:</p>

<pre><code>[Suppliers] =&gt; stdClass Object
                (
                    [@size] =&gt; 1
                    [name] =&gt; Supplier Name
                    [Supplier] =&gt; stdClass Object
                        (
                            [@chainCode] =&gt; EP
                            [@id] =&gt; 13
                        )

                )
</code></pre>

<p>I know how to get the <code>name</code> property and display it, but I don't know how to get the properties that start with an '@' sign ... What is it and how can I get its value?</p>
