<section class="phpdocumentor-description"><p>To make a <code class="prettyprint">protected</code> or <code class="prettyprint">private</code> property readable, provide a method named
<code class="prettyprint">_magicGet{Property}()</code> which handles the reading. Replace <code class="prettyprint">{Property}</code> in
the method's name with the name of the actual property (with an uppercase
first letter).</p>
<blockquote>
<p>Example: If the property is named <code class="prettyprint">$fooBar</code>, the &quot;magic&quot; method has to be
<code class="prettyprint">_magicGetFooBar()</code>. This method is then called when <code class="prettyprint">$fooBar</code> is read in
a context where it normally would not be accessible.</p>
