This project is an example of a Zend Application which can use a combination of external login providers (Facebook, Twitter, Google) to perform authentication and use their API's.

To clone this repository, do the following:

git clone --recursive git://github.com/thebestsolution/ZendMultipleAuthentications DESTINATION
cd DESTINATION

If you have PHP version < 5.3 (no namespace support):

git checkout no_namespaces
git submodule update

You also have to download the Zend framework. I only tested the application with Zend Framework version 1.11.11 (link), but it should work with older versions. If you have any trouble place a comment.

Unpack the archive and copy the Zend folder to the library folder of the checked out repository folder.

Change the application.ini (can be found in application/configs), to your configuration.

Change YOUR_HOSTNAME with the server name of your vhost. If your app doesn't run at the siteroot you have to change some stuff in the Bootstrap.php. If you need any help place a comment
