Verifying the existence of a method
<p>Is possible to verify the existence of a method without instantiating the class in php? How I do it?</p>

<p>I need to check in real time the existence of a method to build my links, but instantiate the classes is very expensive and unnecessary (don't need the classes at the time), so <code>is_callable</code> and <code>method_exists</code> are not an option.</p>
