Oauth for PHP 5.4 Windows x86


This is not my source so im not sure how stable ,but it was the only option I’ve found after about an hour and a half of searching.

Throw the file into your php/ext folder

Edit your php.ini to include the extension


I had this same problem. I think wamp installs using win32 bits by default. Even if you are running windows 64bit OS. So download the 86x version here For PHP version 5.5 .
Extract the Zip file and copy the php_oauth.dll found in your extract to C:/wamp/bin/php/php5.5.12/ext Click on your wamp server, goto PHP>php.ini, add thisextension=php_oauth.dll to a place where you find similar text or anywhere. Now exit your wamp server. Start it up again and in PHP>PHP extensions you should see php_oauth ticked. However, if you still encounter problems goto PHP error logto get a clue. Cheers!
