如何在服务器上找到Zend的安装位置？

Question

I'm trying to use Zend's "Zend_Service_Amazon" class in my php script, but I'm not sure where it is installed. I'm assuming I need to include the path to Zend before trying to call methods based on this error I get:

Fatal error: Class 'Zend_Service_Amazon' not found in /public_html/path/zend.php on line 3

I know Zend is installed based on the php -v output of:

Zend Engine v2.2.0, Copyright (c) 1998-2010 Zend Technologies
    with the ionCube PHP Loader v4.2.2, Copyright (c) 2002-2012, by ionCube Ltd., and
    with Zend Optimizer v3.3.9, Copyright (c) 1998-2009, by Zend Technologies

So how do I find out where it resides and how to include it in my php script?

If it makes a difference, I'm using cPanel.

1. Based on the php -v output we can say that Zend Optimizer is installed. Nothing about Zend Framework there
2. Zend Framework is a set of php scripts, nothing else. You don't need to have it installed on the server
3. There is no way rather than finding through all the filesystem if ZF is installed somewhere
4. As long as it is a good idea to rely on a particular software version - just distribute your script with zend framework
