我想使用PHP DateInterval函数并制定下面的代码,尝试根据原始事件Start Date,Finish Date和EndDate of Recurrence创建一个定期事件.

//user defined event start and finish dates
$eventStart = new DateTime( '2011-01-31 09:00:00' );
$eventFinish = new DateTime( '2011-01-32 17:00:00' );

//user defined event recurring end date
$endRecurring = new DateTime( '2011-05-31 23:59:59' );

//define for recurring period function
$begin = $eventStart;
$end = $endRecurring;

//define our interval
$interval = DateInterval::createFromDateString('next friday');
$period = new DatePeriod($begin,$interval,$end,DatePeriod::EXCLUDE_START_DATE);

//loop through and create new dates for recurring events
foreach ( $period as $dt )
  $recurringStartDate = $dt->format( "l Y-m-d H:i:s\n" );
  $recurringEndDate = ?NOT SURE HOW TO PROCESS THE END DATE IN THIS START DATE FOREACH LOOP?

这应该有希望创建一个新的事件开始日期列表.但我还需要为我的定期事件定义新的结束日期.我该怎么做呢？我是否需要在事件开始日期foreach循环中处理此问题？

我的另一个问题是如何组合多个dateIntervals来处理每周一,周三和周五的重复？目前只有一个dateIntervals像下周五一样工作

谢谢你的帮助！
