This could possibly be the fastest crontab expression parser in PHP7 currently. Real benchmarks show that it is somewhere between 6-9x faster than existing solution.

Neat simple API

Just set a single cron entry for your PHP based scheduler once and for all like so:

* * * * * php /path/to/scheduler.php

Then all you need to do is invoke your due jobs in scheduler.php, this is where cron-expr comes in play: it tells you if specific job/task is due at the moment with simple api. See a quick simple example below:

$job1Schedule = '*/5 * * * *';
$isJob1Due    = Ahc\Cron\Expression::isDue($job1Schedule);

// run job 1 if due and so on for job 2 etc... !

Also supports some humanly tags for representing schedule intervals like @hourly, @daily, @10minutes.
