Note that the public member $class contains the name of the class in which the method has been defined:

<?php
class A {public function __construct() {}}
class B extends A {}

$method = new ReflectionMethod('B', '__construct');
echo $method->class; // prints 'A'
?>

I have written a function which returns the value of a given DocComment tag.

Full example:

<?php

header('Content-Type: text/plain');

class Example
{
    /**
     * This is my DocComment!
     *
     * @DocTag: prints Hello World!
     */
    public function myMethod()
    {
        echo 'Hello World!';
    }
}

function getDocComment($str, $tag = '')
{
    if (empty($tag))
    {
        return $str;
    }

    $matches = array();
    preg_match("/".$tag.":(.*)(\\r\\n|\\r|\\n)/U", $str, $matches);

    if (isset($matches[1]))
    {
        return trim($matches[1]);
    }

    return '';
}

$method = new ReflectionMethod('Example', 'myMethod');

// will return Hello World!
echo getDocComment($method->getDocComment(), '@DocTag');

?>

Maybe you can add this functionality to the getDocComment methods of the reflection classes.
