You’re in luck – this was just added in Beta 4 – see here for details
Added App::environment method.
Edit: these are now a number of various ways to get the environment variable as of Laravel 4.1
App::environment()
app()->environment()
app()->env
$GLOBALS['env'] // not recommended - but it is possible
You can also specifically check for if the current environment is set to ‘local’
App::isLocal()
app()->isLocal()
…or ‘production’
App::isProduction()
app()->isProduction()
You can also specifically check for if the current environment is set to ‘testing’
App::runningUnitTests()
app()->runningUnitTests()
