A dependable php environment
Because we dont always know if $_ENV is available, (*1)
Habitat is a light weight wrapper over PHP's environment variable
functionality. Habitat allows the retrieval of all environment variables
when the ini setting variables_order does not contain the E flag, (*2)
Habitat delegates most functionality to the native php functions getenv and putenv.
If $_ENV is not available due to the variables_order ini setting, then Habitat's getAll
method will still allow access to all variables that are in $_ENV., (*3)
use Habitat\Habit;
//equivalent of getenv('FOO')
$foo = Habitat::getenv('FOO');
//equivalent of putenv('FOO=BAR')
$wasSet = Habitat::putenv('FOO=BAR');
/**
* Returns $_ENV if set, otherwise set $_ENV via phpinfo() and
* return it
*/
$all = Habitat::getAll();
Habitat can support the cli and html varieties of phpinfo. It will detect the current sapi
and use the appropriate method to populate $_ENV, (*4)
