How do I set environment variables in WAMP

Question

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

Answer 1

Depending on exactly what you need to accomplish you probably need to look at using putenv() or if you want to change an apache environment variable, apache_setenv().

Answer 2

Perhaps they show up in $_SERVER?

Answer 3

Please note that when using putenv() the value will not be available in $_ENV, and you have to use getenv() to obtain the value.

Answer 4

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
