> **WARNING**: This class was written back in 2010 ! Its pretty much untested with all PHP versions > 5.6.0 and might act funny. I mostly pushed it to GitHub for easier access and in case if somebody is looking for a simple cron-parser.

tdCron
======

[](#tdcron)

tdCron is a ***very*** simple class to parse cron-expressions and calculate schedules.

For something more sophisticated (and WAY more modern) you can take a look at the [cron-expression](https://github.com/dragonmantank/cron-expression) package by Michael Dowling and Chris Tankersley.

Getting Started
---------------

[](#getting-started)

### Installation

[](#installation)

Just include `class.tdcron.php` and `class.tdcron.entry.php` in your project and you're done.

Documentation
-------------

[](#documentation)

As i mentioned before - this class is really, really simple :-)

Please just look at the code in `test.php` and `class.tdcron.php` - its reasonably well documented and should be pretty easy to understand.

It basically comes down to calling `tdCron::getNextOccurrence()` or `tdCron::getLastOccurrence()` with your cron-expression as the first parameter and an optional reference-time as the second parameter.

Lets say you've got a cron-expression like `5 0 * 8 2` (so something at 00:05 on every tuesday in august). You could use something like

```
echo 'next: '.date('d.m.Y, H:i:s', tdCron::getNextOccurrence('5 0 * 8 2');

```

to see when it should run the next time.

Running the tests
-----------------

[](#running-the-tests)

There aren't any "real" tests included with the class (so you won't find any PHPUnit-stuff here). You can find a bunch of edge-cases in the test.php / test.data.php files that were used to test the class during development.
