How do I set environment variables in WAMP

Question

I am trying to get an environment variable to show up in `$_ENV` in my codeigniter app. How do i do this?

Accepted Answer

You can set an environment variable in a few different ways. Some (not all?) are:

- put them in .htaccess files

- specify on the command line

- specify them in your Apache config file like this:

Apache config:

```
SetEnv env_var_name env_var_value
```
