php - Where should be stored the environment dependent configs in a Zend Framework 2 application? -

a zf2 application contains/nneds lot of different config files: /config/application.config.php, /config/autoload/global.php, /config/autoload/local.php, /module/***/config/module.config.php.

now i've written module, covers caching functionality application, , need different values livetime of items in local/dev , live environment. able switch cache type dependent on environment.

where should such stuff sored? in /config/autoload/global.php , /config/autoload/local.php? if yes: should first retrieved these files in module class (e.g. in onbootstrap() method) or used directly, it's needed?

(it great, if show primitive example saving , getting such config data.)

the solution, i'm using is:

/config/autoload/global.php and/or /config/autoload/local.php

return array(     // db credentials     'db' => array(         'username'  => ...,         'password'  => ...,         'dbname'    => ...,         'host'      => ...,     ),     'cache_ttl' => 'global/local value cache live time', ); 

cache module class

class module {      private $moduleconfig;      public function onbootstrap(mvcevent $mvcevent) {             $application = $mvcevent->getparam('application');             $this->moduleconfig = $application->getconfig();     }      ...      public function getserviceconfig() {         try {             return array (                 'factories' => array(                     ...                     'zend\cache\adapter\memcachedoptions' => function ($servicemanager) {                         return new memcachedoptions(array(                             'ttl'           => $this->moduleconfig['cache_ttl'],                             ...                         ));                     },                     ...                 )             );         }         ...     } } 

it works fine, i'm pretty sure, it's not best practice / recomended way.
