Cron expression generator is a beautiful tool for PHP applications. Of course, the primary feature of this package is the ability to generate cron expressions.

Features

Cron expressions generator
Pre built expressions
Custom expressions
Well documented
Well tested
Compatible with Laravel

Requirements

PHP 8.0 and above

Installation

You can install the package via composer:

composer require butschster/cron-expression-generator

That's it!

Usage

Creates a new generator

use Butschster\CronExpression\Generator;
use Cron\CronExpression;

$generator = new Generator();
// or
$generator = new Generator(new CronExpression('* * * * *'));
// or
$generator = Generator::create();
// or
$generator = Generator::create(new CronExpression('* * * * *'));

Gets expression object

$expression = $generator->getExpression(); // \Cron\CronExpression

Converts expression to a string

echo $generator->toExpression(); // * * * * *

echo (string) $generator; // * * * * *

echo (string) $generator->getExpression(); // * * * * *

echo $generator->getExpression()->getExpression(); // * * * * *

Sets specific cron expression

echo $generator->cron('* */3 * * *'); // * */3 * * *

echo $generator->cron('* */3 * * *')->everyTwoMinutes(); // */2 */3 * * *

use Butschster\CronExpression\Parts\Days\SpecificDays;
use Butschster\CronExpression\Parts\DaysOfWeek\SpecificDaysOfWeek;
use Butschster\CronExpression\Parts\Hours\EveryHour;
use Butschster\CronExpression\Parts\Minutes\EveryMinute;

// * */2 5,10,15,20,25,30 3,6,9,12 1,3,5,0

echo $generator
    ->yearly()
    ->months(Generator::MAR, Generator::JUN, Generator::SEP, Generator::DEC)
    ->daysOfMonth(5, 10, 15, 20, 25, 30)
    ->daysOfWeek(Generator::MONDAY, Generator::WEDNESDAY, Generator::FRIDAY, Generator::SUNDAY)
    ->everyTwoHours()
    ->everyMinute();

// or

echo $generator
    ->set(
        new SpecificMonths(Generator::MAR, Generator::JUN, Generator::SEP, Generator::DEC),
        new SpecificDays(5, 10, 15, 20, 25, 30),

        new EveryMinute()
    );

Gets next run date

See: https://github.com/dragonmantank/cron-expression#usage

echo $generator->monthlyOn(15, 12)->getExpression()->getNextRunDate(); // DateTime

Using with laravel

<?php

namespace App\Console;

use Butschster\CronExpression\Generator;
use Illuminate\Console\Scheduling\Schedule;
use Illuminate\Foundation\Console\Kernel as ConsoleKernel;
use Illuminate\Support\Facades\DB;

class Kernel extends ConsoleKernel
{
    protected function schedule(Schedule $schedule)
    {
        $schedule->command('emails:send Taylor --force')->cron(
            Generator::create()->daily()
        );
    }
}

Create custom expressions

To create a custom expression class you need implement Butschster\CronExpression\PartValueInterface

Example 1

use Butschster\CronExpression\PartValueInterface;
use Cron\CronExpression;

class Quarterly implements PartValueInterface
{
    public function updateExpression(CronExpression $expression): void
    {
        $expression->setPart(CronExpression::MONTH, '1-12/3');
    }
}

Using

echo \Butschster\CronExpression\Generator::create()->set(new Quarterly()); // * * * 1-12/3 *

Example 2

use Butschster\CronExpression\Parts\Days\SpecificDays;
use Butschster\CronExpression\Parts\Hours\SpecificHours;
use Butschster\CronExpression\Parts\Minutes\SpecificMinutes;
use Butschster\CronExpression\Parts\Months\SpecificMonths;
use Butschster\CronExpression\PartValueInterface;
use Cron\CronExpression;
use DateTimeInterface;

class DateTime implements PartValueInterface
{
    public function __construct(private DateTimeInterface $time)
    {
    }

    public function updateExpression(CronExpression $expression): void
    {
        $parts = [
            new SpecificMinutes((int)$this->time->format('i')),
            new SpecificHours((int)$this->time->format('G')),
            new SpecificDays((int)$this->time->format('j')),
            new SpecificMonths((int)$this->time->format('n'))
        ];

        foreach ($parts as $part) {
            $part->updateExpression($expression);
        }
    }
}

Using

echo \Butschster\CronExpression\Generator::create()->set(new DateTime(new \DateTime('2021-02-05 12:34:26'))); // 34 12 5 2 *
