Zend Debugger for PHP 5.3

It's hard for me to understand, why Zend is not able to provide the Zend_Debugger extension for PHP 5.3. You can download the binaries for older PHP versions at http://downloads.zend.com/pdt/server-debugger/, but the ones provided there are only useable for PHP 5.2.x

But there is a way to get a debugger binary that works with PHP 5.3. Just download the latest Zend Server Community Edition (http://www.zend.com/de/products/server/downloads-all)  and take a look at the zend.7z file in the package.
If you open this package you can find the binary in the path: /zend/lib/debugger/php-5.3.x/ZendDebugger.so

Extract that file into your PHP modules directory and include it in your php.ini
Restart your webserver and voilà it works...

And if you do not want to download the whole Zend Server Package, just download the ZendDebugger_5.3.x.so from here.
