Installation

Using composer, add a requirement for poliander/cron to your composer.json file:

composer require poliander/cron

Examples

Validate a certain crontab expression:

use Poliander\Cron\CronExpression;

$expression = new CronExpression('15,45 */2 * * *');
$isValid = $expression->isValid(); // returns true

Check whether a given point in time is matching a certain cron expression:

use Poliander\Cron\CronExpression;

$expression = new CronExpression('45 9 * * *');
$dt = new \DateTime('2014-05-18 09:45');
$isMatching = $expression->isMatching($dt); // returns true

Match an expression across different time zones:

use Poliander\Cron\CronExpression;

$expression = new CronExpression('45 9 * * *', new DateTimeZone('Europe/Berlin'));
$dt = new \DateTime('2014-05-18 08:45', new DateTimeZone('Europe/London'));
$isMatching = $expression->isMatching($dt); // returns true

Calculate next timestamp matching a Friday, the 13th:

use Poliander\Cron\CronExpression;

$expression = new CronExpression('* * 13 * fri');
$when = $expression->getNext();
