How to add multi-domain support in CodeIgniter?

Question

I need the support of city1.example.com , city2.example.com , city3.example.com in CodeIgniter.

Unfortunately, $config['base_url']config.php strictly sets the base URL.

What is the best way to learn the structure to support different subdomains?

Answer 1

You should probably just look for Codeigniter.com the next time, as all of this is on the wiki:
