Ok, but your use of $zf_path and $zf_ver makes the whole
autoloaderZfPath, autoloaderZfVersion application.ini directives moot,
correct? What I don't understand is, how does one use
Zend_Loader_Autoloader::setZfPath(), without first loading some
components of the Zend Framework?
What I've encountered is that, as soon as you include/instantiate
Zend_Loader_Autoloader, you've sullied the namespace, require_once
won't look in the same directory as the original version of ZF that
you used to include the autoloader, therefore, any duplicate
require_once's will cause duplicate class errors.
So, my question still stands, how does one use
Zend_Loader_Autoloader::setZfPath(), where the ZF path will be
different from the one used to include the autoloader?
