PHP will not call an overloaded method from within the same overloaded method.
118
+
That means, for example, writing <code>return $this->foo</code> inside of
119
+
<link linkend="object.get">__get()</link> will return <literal>null</literal>
120
+
and raise an <constant>E_WARNING</constant> if there is no <literal>foo</literal> property defined,
121
+
rather than calling <link linkend="object.get">__get()</link> a second time.
122
+
However, overload methods may invoke other overload methods implicitly (such as
123
+
<link linkend="object.set">__set()</link> triggering <link linkend="object.get">__get()</link>).
