This article mainly introduces the analysis of PHP's Laravel scheduled task Schedule. It has a certain reference value. Now I share it with you. Friends in need can refer to it.

Premise: The method in this article is to use Linux's crontab scheduled tasks help implement Laravel scheduling (Mac too).
1. First add the Crontab scheduled task. Here is just a brief introduction.
Use the command crontab -e to add the following content

* * * * * /usr/local/bin/php /usr/local/var/www/projectName/artisan schedule:run >> /dev/null 2>&1

The above command Crontab will adjust Laravel's schedule command every minute, and then Laravel will judge and execute the task.
Note: Pay attention to the directories of php and artisan, which php can view the php directory
***** Your command
In addition, the 5 * in front of the above command represent respectively Minutes, hours, days, months, weeks.
Minute: an integer from 0-59, the default * and */1 represent 1 minute.
Hour: an integer from 0-23.
Day: an integer from 1-31.
Month: an integer from 1 to 12.
Week: an integer from 0 to 7, both 0 and 7 represent Sunday.
crontab -l can list the current scheduled tasks.

2. Add Laravel scheduling task.
1. Define your scheduling task in the App\Console\Kernel class:

<?php

namespace App\Console;

use Illuminate\Console\Scheduling\Schedule;
use Laravel\Lumen\Console\Kernel as ConsoleKernel;
use Log;class Kernel extends ConsoleKernel
{    /**
     * The Artisan commands provided by your application.
     * 定义Artisan命令
     * @var array
     */    protected $commands = [
                \App\Console\Commands\test::class,

    ];    /**
     * Define the application&#39;s command schedule.
     * 定义调度任务
     * @param  \Illuminate\Console\Scheduling\Schedule  $schedule
     * @return void
     */    protected function schedule(Schedule $schedule)
    {        //方法一://            $schedule->call(function () {//                Log::info(&#39;任务调度&#39;);//            })->everyMinute();        //方法二:
        $schedule->command(&#39;test&#39;)->everyMinute();
    }
}

Two implementation methods are given above. Method one is to use closures, and method two is to use Artisan commands.
There are many scheduling times:
->cron('* * * * *'); Run tasks on a custom Cron schedule
->everyMinute(); Run once every minute Task
->everyFiveMinutes(); Run a task every five minutes
->everyTenMinutes(); Run a task every ten minutes
->everyThirtyMinutes(); Run a task every thirty minutes
->hourly(); Run the task every hour
->daily(); Run the task every day at 0:00 AM
->dailyAt('13:00'); Run the task every day at 13:00 Task
->twiceDaily(1, 13); Run the task every day at 1:00 & 13:00
->weekly(); Run the task once a week
->monthly(); Every Run the task once a month
There are additional methods, please refer to: http://laravelacademy.org/post/235.html

Continue the operation of method two:
3. Define Artisan Command method:

<?php namespace App\Console\Commands;

use Illuminate\Console\Command;
use Log;class test extends Command {    /**
     * The console command name.
     *
     * @var string
     */    protected $name = &#39;test:putcache&#39;;    /**
     * The console command description.
     *
     * @var string
     */    protected $description = &#39;test controller&#39;;    /**
     * Execute the console command.
     *
     * @return mixed
     */
    public function handle()
    {            //这里做任务的具体处理,可以用模型
            Log::info(&#39;任务调度&#39;.time());
    }

}

Okay, the above can execute the scheduled task. There is a little trick. If the above task is not executed, you can use the command php artisan list to print out some error messages
