ASF PHP Development Configuration information Resident system memory

This article mainly introduces the development of ASF PHP configuration information Resident system memory, has a certain reference value, now share to everyone, the need for friends can refer to

Comparison between traditional MVC and ASF

The traditional MVC framework

Each request will reload the configuration file. Even if the configuration file content is not updated, it will be reloaded once. This is a very bad design. (Open Opcache case, still have the process time of execution)

ASF Framework

The contents of the read to configuration file are saved to the system memory, and the next request goes directly to the memory to read the data. ASF also provides a very simple configuration to implement the Config Cache.

What scenario opens config cache appropriate?

• It is recommended that you open it in a Web application scenario, and that later versions may be enabled by default

• In CLI, multi-threaded mode is also in effect, but the PHP script is released after each execution

• Supported data types are: strings, arrays, integers, Boolean, doubles, floats, null

Flow chart

Turn on caching methods

<?phpini_set (' asf.cache_config_enable ', 1); /* Open config file cache */ini_set (' Asf.cache_config_expire ', 300); /* Set cache number of seconds after expiration, seconds by default */

Frame entry mode load Php/ini configuration file

<?phpdefine (' App_path ', DirName (__dir__));/* Cache config.ini File */$app = new Asf\application (App_path. '/config/config.ini '); $app->run ();

asf\config\php Loading PHP configuration files

<?php$conf_php =  new asf\config\php (Config_path. '/config.db.php ');

Asf\config\ini Loading Ini configuration file

<?php$conf_ini =  new Asf\config\ini (Config_path. '/config.redis.ini ');

Read configuration content method

<?phpprint_r (Asf\application::getinstance ()->getconfig ()->toarray ());p Rint_r (Asf\Config::get () ToArray ());

Performance testing

In the case of opening Opcache, a simple Config Cache performance test was done, ab-c100-n10000

Configuration items in a configuration file the complexity of the item is connected to the performance index in a linear way.

Turn on cache asf.cache_config_enable = 1

Tips

The Cache Config is not based on shared memory, it is based on the PHP process, there is no shared memory lock problem.
