+# PHP iCal Parser
+
+[![PHP Tests](https://github.com/OzzyCzech/icalparser/actions/workflows/php.yml/badge.svg)](https://github.com/OzzyCzech/icalparser/actions/workflows/php.yml)
+[![Latest Stable Version](https://poser.pugx.org/om/icalparser/v/stable)](https://packagist.org/packages/om/icalparser)
+[![Total Downloads](https://poser.pugx.org/om/icalparser/downloads)](https://packagist.org/packages/om/icalparser)
+[![License](https://poser.pugx.org/om/icalparser/license)](https://packagist.org/packages/om/icalparser)

+
+Internet Calendaring Parser [rfc2445](https://www.ietf.org/rfc/rfc2445.txt) or iCal parser is simple PHP class for parsing format into array.
+
+[!["Buy Me A Coffee"](https://www.buymeacoffee.com/assets/img/custom_images/orange_img.png)](https://www.buymeacoffee.com/ozzyczech)
+
+## How to install
+
+The recommended way to is via Composer:
+
+```shell script
+composer require om/icalparser
+```
+
+## Usage and example
+
+```php
+<?php
+use om\IcalParser;
+require_once '../vendor/autoload.php';
+
+$cal = new IcalParser();
+$results = $cal->parseFile(
+	'https://www.google.com/calendar/ical/cs.czech%23holiday%40group.v.calendar.google.com/public/basic.ics'
+);
+
+foreach ($cal->getEvents()->sorted() as $event) {
+	printf('%s - %s' . PHP_EOL, $event['DTSTART']->format('j.n.Y'), $event['SUMMARY']);
+	
+}
+```
+
+Each property of each event is available using the property name (in capital letters) as a key. 
+There are some special cases:
+
+- multiple attendees with individual parameters: use `ATTENDEES` as key to get all attendees in the following scheme:
+```php
+[
+	[
+		'ROLE' => 'REQ-PARTICIPANT',
+		'PARTSTAT' => 'NEEDS-ACTION',
+		'CN' => 'John Doe',
+		'VALUE' => 'mailto:john.doe@example.org'
+	],
+	[
+		'ROLE' => 'REQ-PARTICIPANT',
+		'PARTSTAT' => 'NEEDS-ACTION',
+		'CN' => 'Test Example',
+		'VALUE' => 'mailto:test@example.org'
+	]
+]
+```
+- organizer's name: the *CN* parameter of the organizer property can be retrieved using the key `ORGANIZER-CN`
+
+You can run example with [PHP Built-in web server](https://www.php.net/manual/en/features.commandline.webserver.php) as follow:
+
+```shell
+php -S localhost:8000 -t example
+```
+
+## Requirements
+
+- PHP 8.0+
+
+## Run tests
+
+iCal parser using [Nette Tester](https://github.com/nette/tester). The tests can be invoked via [composer](https://getcomposer.org/).
+
+```shell script
+composer update
+composer test
+```

+ * A class to store Frequency-rules in. Will allow a easy way to find the

+ *
+ * No - this is so not pretty. But.. ehh.. You do it better, and I will
+ * gladly accept patches.
+ *
+ * Created by trail-and-error on the examples given in the RFC.
+ *
+ * TODO: Update to a better way of doing calculating the different options.
+ * Instead of only keeping track of the best of the current dates found
+ * it should instead keep a array of all the calculated dates within the
+ * period.
+ * This should fix the issues with multi-rule + multi-rule interference,
+ * and make it possible to implement the SETPOS rule.
+ * By pushing the next period onto the stack as the last option will
+ * (hopefully) remove the need for the awful simpleMode
