In particular, it deals with console requests * through a command-based approach: * <ul> * <li>A console application consists of one or several possible user commands;</li> * <li>Each user command is implemented as a class extending {@link CConsoleCommand};</li> * <li>User specifies which command to run on the command line;</li> * <li>The command processes the user request with the specified parameters.</li> * </ul> * * The command classes reside in the directory {@link getCommandPath commandPath}. * The name of the class follows the pattern: <command-name>Command, and its * file name is the same the class name. For example, the 'ShellCommand' class defines * a 'shell' command and the class file name is 'ShellCommand.php'. * * To run the console application, enter the following on the command line: * <pre> * php path/to/entry_script.php <command name> [param 1] [param 2] ... * </pre> * * You may use the following to see help instructions about a command: * <pre> * php path/to/entry_script.php help <command name> * </pre> * * @author Qiang Xue <qiang.xue@gmail.com> * @version $Id: CConsoleApplication.php 1361 2009-08-23 00:29:19Z qiang.xue $ * @package system.console * @since 1.0 */ class CConsoleApplication extends CApplication { /** * @var array mapping from command name to command configurations. * Each command configuration can be either a string or an array. * If the former, the string should be the file path of the command class. * If the latter, the array must contain a 'class' element which specifies * the command's class name or {@link YiiBase::getPathOfAlias class path alias}. * The rest name-value pairs in the array are used to initialize * the corresponding command properties.
