env vars

when using linux can set environment vars this:

$ export db_host="localhost"  $ export db_name="dbname" ... 

thus can grab vars php this:

$ php -r 'var_dump($_env["db_name"]);' 

or:

$ php -r 'var_dump(getenv["db_name"]);' 

in order set env vars on windows follow link: how create environmental variable windows 7

propel

on propel, must set parameters (propel.yaml file):

propel:   database:       connections:           default:               adapter: mysql               classname: propel\runtime\connection\debugpdo               dsn: mysql:host=%env.db_host%;dbname=%env.db_name%
