本文实例讲述了Yii框架创建cronjob定时任务的方法。分享给大家供大家参考，具体如下：
1. 添加环境配置
protected/config/console.php
|

<?php
require_once('env.php');
// This is the configuration for yiic console application.
// Any writable CConsoleApplication properties can be configured here.
return array(
'basePath'=>dirname(__FILE__).DIRECTORY_SEPARATOR.'..',
'name'=>'CMS Console',
// application components
'components'=>array(
//Main DB connection
'db'=>array(
'connectionString'=>DB_CONNECTION,
'username'=>DB_USER,
'password'=>DB_PWD,
'enableParamLogging'=>true,
),
'log'=>array(
'class'=>'CLogRouter',
'routes'=>array(
array(
'class'=>'CFileLogRoute',
'levels'=>'error, warning',
),
),
),
),
);
|
2. 添加定时任务执行模块
protected/commands/crons.php
|
1
2
3
4
5
6
7
8
|
<?php
defined('YII_DEBUG') or define('YII_DEBUG',true);
// including Yii
require_once('/../framework/yii.php');
// we'll use a separate config file
$configFile='/config/console.php';
// creating and running console application
Yii::createConsoleApplication($configFile)->run();
|
3. 添加具体的定时任务
定时任务通常是一个命令行程序,从CConsoleCommand类派生,比如
protected/commands/TestCommand.php
|
1
2
3
4
5
6
|
class TestCommand extends CConsoleCommand
{
public function run($args) {
//todo
}
}
|
4. 创建cronjob
|
1
|
30 0 * * * www php /path/to/crons.php Test >>/path/to/logs/test.log
|
5. 传入参数给定时任务中的run($params)
|
1
|
30 0 * * * www php /path/to/crons.php Test param1 param2 ...
|
希望本文所述对大家基于Yii框架的PHP程序设计有所帮助。
