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.

arrays - Algorithm to find ideal starting spot in a circle -

-
so problem have been debating such: your given array of integers representing circle. then, have pick spot in circle start. place start, compare value @ array number of steps took there , if steps less or equal number, include in final set. find place start have elements in set. ex, a=[0, 1, 2] if start @ index=0, then: a[0]=0 < =0 0 included a[1]=1 < =1 1 included a[2]=2 < =2 2 included final set: {0,1,2} if start @ index=1, then: a[1]=1 > 0 1 not included a[2]=2 > 1 2 not included here loop around a[0]=0 > 2 0 included final set: {0} if start @ index=2, then: a[2]=2 > 0 2 not included, here loop around a[0]=0 < = 1 0 included a[1]=1 < = 2 1 included final set: {0,1} so in trivial case, starting position index=0 best position results in final set elements. brute force method of finding obvious, trying find more efficient method. attempts far have been examine trying find max intersect of viable starting ranges calculated each element in arr...

problem? bootloader (autoloader) not seem working properly, or i'm missing something. here simplified code. the code below returns class "skeleton" not exist. on index.php file. index.php <?php include 'bootloader.php'; use skeleton\html\loginheader; $tool = new skeleton/html/loginheader(); bootloader.php <?php function boot($classname) { $filename = ''; $namespace = ''; // sets include path "src" directory $includepath = dirname(__file__).directory_separator.'src'; if (false !== ($lastnspos = strripos($classname, '\\'))) { $namespace = substr($classname, 0, $lastnspos); $classname = substr($classname, $lastnspos + 1); $filename = str_replace('\\', directory_separator, $namespace) . directory_separator; } $filename .= str_replace('_', directory_separator, $classname) .
