This time I will bring you a detailed explanation of the steps to create a scheduled task through the console command in the yii framework. What are the precautions for creating a scheduled task through the console command in the yii framework. The following is a practical case, let’s take a look. one time.

Assume that the Yii project path is /home/apps/

1, create the file /home/apps/protected/commands/crons.php

<?php
$yii = &#39;/home/apps/framework/yii.php&#39;;
require_once
($yii); 
$configFile = 
dirname
(FILE).&#39;/../config/console.php&#39;;
Yii::createConsoleApplication($configFile)->run();

Configuration file /home/apps/protected/config/console.php, configure required components, database connections, logs and other information, the format is similar to the main configuration file main.php.

<?php  return array(     &#39;basePath&#39;=>dirname(FILE).DIRECTORY_SEPARATOR.&#39;..&#39;,    &#39;name&#39;=>&#39;Emergency&#39;,    &#39;import&#39;=>array(              &#39;application.models.*&#39;,            &#39;application.components.*&#39;,             &#39;application.extensions.*&#39;,    ),    &#39;components&#39;=>array(        &#39;log&#39;=>array(            &#39;class&#39;=>&#39;CLogRouter&#39;,            &#39;routes&#39;=>array(                array(                    &#39;class&#39;=>&#39;CFileLogRoute&#39;,                    &#39;levels&#39;=>&#39;info, warning, error&#39;,                ),            ),        ),         &#39;db&#39;=>array(            &#39;class&#39;=>&#39;application.extensions.PHPPDO.CPdoDbConnection&#39;,            &#39;pdoClass&#39; => &#39;PHPPDO&#39;,            &#39;connectionString&#39; => &#39;mysql:host=xxxx;dbname=xxx&#39;,            &#39;emulatePrepare&#39; => true,            &#39;username&#39; => &#39;xxx&#39;,            &#39;password&#39; => &#39;xxx&#39;,            &#39;charset&#39; => &#39;utf8&#39;,            &#39;tablePrefix&#39; => &#39;tbl_&#39;,        ),    ), 
    &#39;params&#39; => require(&#39;params.php&#39;),);

3. Create a new TestCommand class under /home/apps/protected/commands/ and inherit CConsoleCommand. In TestCommand, you can use the project's configuration information and Yii's various methods.

<?php  
class TestCommand  
extends
 CConsoleCommand  
{  
    public function run()
    {  
        ...
    }  
}

4, create a scheduled task

$ crontab -e
The content is:

1 * * * * /home/php/bin/php -f /home /apps/protected/commands/crons.php Test & is to execute the contents of the TestCommand class in the first minute of every hour. Similarly, you can create other classes under /home/apps/protected/commands/ and use the command Execute.
