Defining Codeigniter global variables using configuration classes_PHP tutorial

The previously mentioned CodeIgniter introduces custom public functions. This article mentions public function implementation, and global variables can also be implemented with the help of helper functions.

However, a more appropriate way may be to use configuration class definition.

CodeIgniter has a main configuration file by default, located in the application/config/config.php path, which defines a bunch of framework-level global configurations, one named Array of $config.

If you need to add global configuration items, you can do it in this file. Considering the separation of custom configuration and framework configuration, it is recommended to create a new file vars.php, and then define it as follows:

/**
 * 工作目录配置
 */
$config['src']['cache'] = FCPATH . '../src/cache';
$config['src']['modules'] = FCPATH . '../src/modules';
$config['src']['www'] = FCPATH . '../src/www';

When used, read in the controller through the following code:

$src = $this->config->item('src');
$cache = $src['cache']

or:

$src = $this->config->item('cache', 'src');

Of course, you need to automatically load this configuration file in application/config/autoload.php.
