Public functions in CodeIgniter cannot be appended, and can be implemented through helper helper functions.
Create a common_helper.php file, define the required public functions, and store them in the application/helpers directory.
Just configure $autoload['helper'] = array('common'); in application/config/.
Global variables can also be implemented with the helper function. However, a more appropriate method may be defined by a configuration class.。
CodeIgniter has a main configuration file by default, located in the application/config/ path, which defines a bunch of framework-level global configurations, an array named $config.
If you need to add global configuration items, you can implement them in this file. Considering the separation of custom configuration and framework configuration, it is recommended thatCreate a new file, and then make the following definition:
* Working directory configuration
*/
$config['src']['cache'] = FCPATH . '../src/cache';
$config['src']['modules'] = FCPATH . '../src/modules';
$config['src']['www'] = FCPATH . '../src/www';
When used, read in the controller via the following code:
$src = $this->config->item('src');
$cache = $src['cache']
or:
Of course, you need to automatically load this configuration file in application/config/ .
