1. Configuration, the components required to perform the task

Task configuration file:/protected/config/console.php

The configuration method is similar to configuring the main file

<?php
// This is the configuration for yiic console application.
// Any writable CConsoleApplication properties can be configured here.
return array(
  &#39;basePath&#39;=>dirname(__FILE__).DIRECTORY_SEPARATOR.&#39;..&#39;,
  &#39;name&#39;=>&#39;My Console Application&#39;,
  // application components
  // 自动载入的模型和组件类
  &#39;import&#39;=>array(
      &#39;application.models.*&#39;,//载入"application/models/"文件夹下的所有模型类
      &#39;application.components.*&#39;,//载入"application/components/"文件夹下的所有应用组件类
      &#39;application.extensions.*&#39;,//载入"application/extensions/"文件夹下的所有应用组件类
  ),
  &#39;components&#39;=>array(
      // uncomment the following to use a MySQL database
      &#39;db&#39;=>array(
          &#39;connectionString&#39; => &#39;mysql:host=localhost;dbname=dbname&#39;,//连接mysql数据库
          &#39;emulatePrepare&#39; => true,
          &#39;username&#39; => &#39;root&#39;,//MySQL数据库用户名
          &#39;password&#39; => &#39;123456&#39;,//MySQL数据库用户密码
          &#39;charset&#39; => &#39;utf8&#39;,//MySQL数据库编码
          &#39;tablePrefix&#39; => &#39;zd_&#39;, //MySQL数据库表前缀
          &#39;enableProfiling&#39;=>true,
          &#39;enableParamLogging&#39;=>true,
      ),
      //加载Email组件
      &#39;mailer&#39; => array(
          &#39;class&#39;   => &#39;application.extensions.mailer.EMailer&#39;,
      ),
  ),
);

Copy after login

2. The task file

is placed in The task file naming method that inherits the CConsoleCommand base class in the /protected/commands/ file directory is Task name Command

For example, GoCommand.php

<?php
/**
 * 自动运行文件
 */
class GoCommand extends CConsoleCommand
{
  /**
   * 死循环输出
   */
  public function run(){
    for($i=1;$i>0;$i++){
      self::echoWord($i);
      sleep(2);//休眠2秒
      //跳出
      if(i==500){
        break;
      }
    }
  }
  /**
   * 输出hollo word
   */
  public function echoWord($i){
    echo "hollo word --$i\n";
  }
}

Copy after login

3. Execute the task

E:\project\app\protected>yiic
Yii command runner (based on Yii v1.1.12)
Usage: E:\zeee\zyd\protected\yiic.php <command-name> [parameters...]
The following commands are available:
