The controller "controllers"
Simply put, the function of the controller is to accept the request. It uses the obtained method, where a function module is loaded through a URI to refresh or submit a presentation layer. The controller uses the $_get auto global variable to determine which module to load.
An example of a request that looks like this:
Http://example.com/index.php?module=login
This looks simple, but not in the process of implementation. Here are some of the argument parts that the controller can identify:
module defines which modules to use, such as the Users module
class defines which feature class to use, such as whether you want the user to login or logout
Event defines which specific event to use
Such a more complex example could explain the final request URL for each of the above argument:
Http://example.com/index.php?module=users&class=login
This request tells the Controller to load the users module, then the login class, and finally runs the Login::__default () default event because there is no specific event defined.
Here is the specific Code section:
