THINKPHP的cron计划任务的实现,利用THINKPHP自带的cli,加上数据库执行记录（记录任务的报错,成功）。
在服务器cron定时任务在网站目录(不是网站根目录)执行php cron.php，网站根目录为Public。
写一个cli的入口文件
cli.php
<?php define('MODE_NAME', 'cli'); // 检测PHP环境 if(version_compare(PHP_VERSION,'5.3.0','<')) die('require PHP > 5.3.0 !'); define('APP_DEBUG', true); // 定义应用目录 define('APP_PATH', __DIR__ . '/Application/'); // 引入ThinkPHP入口文件 require __DIR__ . '/ThinkPHP/ThinkPHP.php';
写一个执行文件
cron.php
define('AUTO_CRON', true); include __DIR__ . '/cli.php';
数据库设计
DROP TABLE IF EXISTS `cron`; CREATE TABLE IF NOT EXISTS `cron` ( `cron_id` int(10) unsigned NOT NULL AUTO_INCREMENT, `name` varchar(255) COLLATE utf8_unicode_ci NOT NULL DEFAULT '', `expression` varchar(255) COLLATE utf8_unicode_ci NOT NULL DEFAULT '', `class` varchar(255) COLLATE utf8_unicode_ci NOT NULL DEFAULT '', `method` varchar(255) COLLATE utf8_unicode_ci NOT NULL DEFAULT '', `type` varchar(30) COLLATE utf8_unicode_ci NOT NULL DEFAULT '', `status` varchar(30) COLLATE utf8_unicode_ci NOT NULL DEFAULT '', `created_at` timestamp NOT NULL DEFAULT '0000-00-00 00:00:00', `updated_at` timestamp NOT NULL DEFAULT '0000-00-00 00:00:00', `run_at` timestamp NULL DEFAULT NULL, `ms` int(10) unsigned NOT NULL DEFAULT '0', `error` text COLLATE utf8_unicode_ci NOT NULL, PRIMARY KEY (`cron_id`), KEY `name` (`name`,`created_at`), KEY `cron_status_index` (`status`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci AUTO_INCREMENT=1 ;
