Hi,
I have created an opensource project on github for my project using php+yii.
It is a base for other sites, hotsites, webapps, webservices…
I have used it a long of time in too many projects from my customer with a huge number of access.
Github link:
You can use it in any projects that you want, free or comercial. If you use it and want post here the project link to we see, thanks.
You can fork to create new features and if you have any suggestions, left me know.
