Recurr is a PHP library for working with recurrence rules (RRULE) and converting them in to DateTime objects.
Recurr was developed as a precursor for a calendar with recurring events, and is heavily inspired by rrule.js.
Recurr is hosted on packagist, meaning you can install it with Composer.
Create a composer.json file
{
"require": {
"simshaun/recurr": "dev-master"
}
}Install composer and run it
wget http://getcomposer.org/composer.phar
php composer.phar install(Optional) Autoload Recurr
require 'vendor/autoload.php';$timezone = 'America/New_York';
$startDate = new \DateTime('2013-06-12 20:00:00', new \DateTimeZone($timezone));
$rule = new \Recurr\RecurrenceRule('FREQ=MONTHLY;COUNT=5', $startDate, $timezone);
$transformer = new \Recurr\RecurrenceRuleTransformer($rule);
print_r($transformer->getComputedArray());- Monthly recurring rules: If your start date is on the 29th, 30th, or 31st, Recurr will skip the months that have less than that number of days. This behavior is configurable:
$timezone = 'America/New_York';
$startDate = new \DateTime('2013-01-31 20:00:00', new \DateTimeZone($timezone));
$rule = new \Recurr\RecurrenceRule('FREQ=MONTHLY;COUNT=5', $startDate, $timezone);
$transformer = new \Recurr\RecurrenceRuleTransformer($rule);
$transformerConfig = new \Recurr\TransformerConfig();
$transformerConfig->enableLastDayOfMonthFix();
$transformer->setTransformerConfig($transformerConfig);
print_r($transformer->getComputedArray());
