Constants versus config items - El Forum - 11-10-2010

I just advised someone to use config/constants for global data as opposed to loading a config item as needed.
So, in CI, what's the difference? If I need global settings is using a constant the solution to discretely loading a config item?

It's the same rule for any PHP coding (and many other languages.) If you anticipate the values ever changing during script execution ($config['base_url'], database config, etc.) use $config. If the value will only ever be set once, define it as a constant instead.
