Site migration problems *RESOLVED*

I have a website on a remote server that works great but I'd like to have a local copy for development purposes.

I've downloaded the site and it gives me several errors including:
Notice: Constant ERR_ORDER_FAILED_ADD already defined
Notice: Undefined index: u_login
Notice: Undefined offset: 0
- these are not thrown on the live site!

I'm presuming that the local PHP setup is causing this but I've checked phpinfo on both servers and they are identical.

PHP ain't my first language so if anyone could lend a hand I would be very grateful.

Cheers

DJ

RESOLVED

I had error_reporting set to E_ALL once I set it to E_ALL & ~E_NOTICE everything was good!
