The PHP Cron Library can be used to get human readable cron expression description and detailed validation messages. Any level of expression complexity is handled.

Code examples
=============

[](#code-examples)

Human readable cron expression description example:

```
$expression = \Sivaschenko\Utility\Cron\ExpressionFactory::getExpression('5 4 8 * *');

echo $expression->getVerbalString(); // "At 04:05, on 8th day of month."

```

Cron expression validation example:

```
$expression = \Sivaschenko\Utility\Cron\ExpressionFactory::getExpression('60 * * * 2- *');

if (!$expression->isValid()) {
    print_r($expression->getValidationMessages());
}

/*
Array
(
    [0] => Minute expression part value "60" is greater than max allowed "59"
    [1] => Missing second part of "range" expression ("2-")
)
*/

```

Functionality examples
======================

[](#functionality-examples)

Examples of expression translation to verbal format:
