**Basic**

**Bulk checks**

When checking for several jobs at once, if more than one of the jobs share equivalent expression

then the evaluation is done only once per go thus greatly improving performnce.

use Ahc\Cron\Expression;

$jobs = [

'job1' => '*/2 */2 * * *',

'job1' => '* 20,21,22 * * *',

'job3' => '7-9 * */9 * *',

'job4' => '*/5 * * * *',

'job5' => '@5minutes', // equivalent to job4 (so it is due if job4 is due)

'job6' => '7-9 * */9 * *', // exact same as job3 (so it is due if job3 is due)

];

// The second param $time can be used same as above: null/time()/date string/DateTime

$dueJobs = Expression::getDues($jobs, '2015-08-10 21:50:00');

// ['job1', 'job4', 'job5']

// Dont like static calls? Below is possible too!

$expr = new Expression;

$dueJobs = $expr->filter($jobs, time());
