set up multiple applications

Are there any reason you need to do it like that? Because that just look like you are going to dig a big hole in the ground and never get out of it.

I would recommend setting up virtual hosts (multiple domains) and send environment variables from apache into CI. And change your application directory path. So you can access it normally.

Hi,
Thanks for your reply.
Here's my need :
I need to run my test code if my url contains "test"
I need to run my prod code if my url contains "prod"
I need to run my code with database application1 id my url contains "application1"
I need to run my code with database application2 id my url contains "application2"

I don't know If I followed the good way, that's why I asked if someone could help me.
