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.
