Asf PHP development configuration information is resident in system memory
Asf PHP development configuration information is resident in system memory
This article mainly introduces the configuration information of Asf PHP development resident in the system memory. It has a certain reference value. Now I share it with you. Friends in need can refer to it.
Comparison between traditional MVC and Asf
Traditional MVC framework
The configuration file will be reloaded with each request. Even if the configuration file content has not been updated, it will be reloaded. This is a very bad design. (When Opcache is turned on, there is still execution time)
Asf framework
The content of the read configuration file is 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 implementation Config Cache.
In what scenarios is it appropriate to enable Config Cache?
It is recommended to enable it in web application scenarios. Later versions may enable it by default
It also takes effect when enabled in CLI and multi-threaded mode, but the PHP script is released every time it is executed.
- ##Supported data types are: strings, arrays, integers, boolean, doubles, floats, null
<?php ini_set('asf.cache_config_enable', 1); /* 开启配置文件缓存 */
ini_set('asf.cache_config_expire', 300); /* 设置缓存多少秒之后过期, 300 seconds by default */
Copy after login

Read configuration content method<?php $conf_ini = new Asf\Config\Ini(CONFIG_PATH . '/config.redis.ini');
<?php print_r(Asf\Application::getInstance()->getConfig()->toArray());
print_r(Asf\Config::get()->toArray());

Performance testWith Opcache turned on, we simply did a Config Cache performance test, ab -c100 -n10000There is a difference between the complexity of the configuration items in the configuration file and the performance indicators.
