O Guia Definitivo do Yii 1.1

A console command should extend from CConsoleCommand and implement its
CConsoleCommand::run method. Optionally, we can override
CConsoleCommand::getHelp to provide some nice help information about the command.
class MyCommand extends CConsoleCommand
{
public function run($args)
{
// $args gives an array of the command-line arguments for this
command
}
}
public function getHelp()
{
return 'Usage: how to use this command';
}
Module
Please refer to the section about modules on how to create a module.
A general guideline for developing a module is that it should be self-contained. Resource
files (such as CSS, JavaScript, images) that are used by a module should be distributed
together with the module. And the module should publish them so that they can be Webaccessible.
Generic Component
Developing a generic component extension is like writing a class. Again, the component
should also be self-contained so that it can be easily used by other developers.
Utilizando Bibliotecas de Terceiros
Yii is carefully designed so that third-party libraries can be easily integrated to further
extend Yii's functionalities. When using third-party libraries in a project, developers often
encounter issues about class naming and file inclusion. Because all Yii classes are
prefixed with letter C, it is less likely class naming issue would occur; and because Yii
relies on SPL autoload to perform class file inclusion, it can play nicely with other libraries
if they use the same autoloading feature or PHP include path to include class files.
Below we use an example to illustrate how to use the Zend_Search_Lucene component
from the Zend framework in a Yii application.
First, we extract the Zend framework release file to a directory under protected/vendors,
assumingprotected is the application base directory. Verify that the fileprotected/vendors/
Zend/Search/Lucene.php exists.
