PHP Class yii2tech\crontab\CronTab

Note: Each system user has his own crontab, make sure you always run this class for the same user. For the web application it is usually 'apache', for the console application - current local user or root. Example usage: php use yii2tech\crontab\CronTab; $cronTab = new CronTab(); $cronTab->setJobs([ [ 'min' => '0', 'hour' => '0', 'command' => 'php /path/to/project/yii some-cron', ], [ 'line' => '0 0 * * * php /path/to/project/yii another-cron' ] ]); $cronTab->apply();
