PHP method_exists not working on class children?
<pre><code>class parent{
   function run($methodname) {
      echo method_exists(__CLASS__, $methodname);      
   }
}

class child extends parent {
   function order(){
      echo 'hello';
   }
}

$test = new child();
$test-&gt;run('order'); //false
</code></pre>

<p>The method_exists cannot find the method order in child class. </p>

<p>How to make it work?</p>
