Mau*_*oto 0 php date intervals
我有这些代码,
$end = strtotime ('last day of previous month') ;
$start = strtotime ("-1 year +1 day", $end) ;
$new ['first'] = date ('Y-m-d',$start) ;
$new ['last'] = date ('Y-m-d',$end) ;
$interval = DateInterval::createFromDateString ('1 month') ;
$period = new DatePeriod($start, $interval, $end) ;
foreach ($periods as $period) {
print_r($period -> date_format('Y-m')) ; echo "<br>";
}

但是,我已通过此消息返回:
遇到未捕获的异常
类型:异常
消息:DatePeriod::__construct():此构造函数接受 (DateTimeInterface、DateInterval、int) 或 (DateTimeInterface、DateInterval、DateTime) 或 (字符串) 作为参数。
有人可以帮助我吗?

您有语法错误和对象初始化错误。这是更正:
$end = strtotime ('last day of previous month') ;
$start = strtotime ("-1 year +1 day", $end) ;
$new['first'] = date ('Y-m-d', $start) ;
$new['last'] = date ('Y-m-d', $end) ;
$interval = DateInterval::createFromDateString ('1 months') ;
$periods = new DatePeriod(new DateTime($new['first']), $interval, new DateTime($new['last'])) ;
foreach ($periods as $period) {
print_r($period->format('Y-m')) ; echo "<br>";
}

问题 1:DatePeriod构造函数接受 DateTime 对象。请查看手册http://php.net/manual/en/class.dateperiod.php
问题 2:您需要$periods在 foreach 中使用的变量
