can run a task every X second with Laravel?

Question

Hy guys, I have read the chapter called scheduling of Laravel's documentation, but I haven't found much information. I'm trying to customize the execution of a task to make it run every 30 seconds. Is there a solution ? Sorry for my english and have a good day.

Answer 1

By default CRON tasks are scheduled in minimal period 1 minute, but there is workaround for your issue.

In Console Kernel you should do something like this:

/**
 * Define the application's command schedule.
 *
 * @param  \Illuminate\Console\Scheduling\Schedule  $schedule
 * @return void
 */
protected function schedule(Schedule $schedule)
{
     $schedule->command('your_command:run', ['--delay'=> 0])->everyMinute();
     $schedule->command('your_command:run', ['--delay'=> 30])->everyMinute();
}

In your Command class you should define the $signature variable that can take the delay parameter.

/**
 * The name and signature of the console command.
 *
 * @var string
 */
protected $signature = 'your_command:run {--delay= : Number of seconds to delay command}';

In the handle method you should read value of this parameter and sleep this task for specific number of second using built-in sleep() function.

/**
 * Execute the console command.
 *
 * @return mixed
 */
public function handle()
{
    // code
    sleep(intval($this->option('delay')));
}

This solution will run your task every 30 seconds, you can multiply number of task with different delay. In this case you need to edit schedule method in Kernel class.
