php - How to cache the application configs in memory in Zend Framework 2? -

one of must-haves performance optimization of zend framework 2 application caching of configurations. idea merge them 1 big config file (or 2 files, e.g. module-classmap-cache.php , module-config-cache.php), config files don't need opened , merged on every request. (see info in official documentation , how-to in article of rob allen "caching zf2 merged configuration"):

application.config.php

return [     'modules' => [         ...     ],     'module_listener_options' => [         ...         'config_cache_enabled' => true,         'config_cache_key' => 'app_config',         'module_map_cache_enabled' => true,         'module_map_cache_key' => 'module_map',         'cache_dir' => './data/cache',     ], ]; 

i'd optimize bit more , load configs in-memory cache (e.g. apcu). provided framework? or have write functionality myself?

the caching mechanism implemented in configlistener class of modulemanager (source of write config & read config). can see there, supported caching method writing cached configuration file.

it instantiated default in defaultlisteneraggregate (source), again hard coded in modulemanagerfactory of mvc module (source).

in order replace own logic, have to:

• replace configlistener own (or @ least extend respective parts)
• change modulemanagerfactory explicitly set own configlistener on defaultlisteneraggregate before gets lazy-created.

while feasible, don't think worth effort. merged config file php file, should cached opcache anyway. , opcache php-optimized in-memory cache. i'd expect faster all-purpose in-memory store.
