Including OAuth in PHP stops OAuth separate Class from working - oauth

Question

I am working with Google Analytics and Google Adwords, and I've installed the OAuth "pecl" package to get the Google Adwords working and now my Analytics code doesn't work.
When I open up my php.ini file and comment out (and restart apache)
extension=oauth.so
The analytics example code works (I adapted it from the OAuth playground that google has open sourced). Is there any way that I could keep my example code from working? I have found that the script crashes on this line:
require_once('common.inc.php');
Common.inc.php looks like this:

I was wondering if anybody had experience with this extension. Perhaps I could rename some of the OAuth classnames? It seems to be that some of these classes are conflicting causing this not to work. I'm going to need to have these scripts working side by side, (ie. under the same php.ini configuration).
Another alternative that I have been wondering about: Is there a way to include an extension in the php.ini file for only one script (Adwords Script)? And then by default not include the extension?
Any advice would help! Thank you

Answer 1

I actually got around this by using dl() to dynamically load the extension
