每年每个月的php - for循环 [英] php - for loop for each month of year

问题描述

我想要一个循环，检查当前月份，未来12个月和过去4个月。

I want a loop that checks the current month, 12 months in the future and 4 months in the past.

例如：今天是8月1日08.我的四月，五月，六月，七月，八月，九月，十月，十一月，十二月，一月，二月，三月，四月，五月，六月，七月和八月。

For example: Today is 1st August 08. My loop should go through April, May, June, July, August, September, October, November, December, January, February, March, April, May, June, July, and August.

我尝试过时间，但我不知道我将来可以如何循环4个月，12个月。

I have tried strotime but I don't know how I can loop 4 months back and 12 months in the future.

这是我的代码

$i = 1; 
$month = strtotime('2013-08-01');

    while($i <= 12) {
        $month_name = date('F', $month);
        echo $month_name;
        echo "<br>";

        $month = strtotime('+1 month', $month);
        $i++;

推荐答案

我认为Yoshi几乎在那里，这是答案，但使用 DatePeriod DateTime 更加一致，并使更易读的代码IMHO： -

I think Yoshi was almost there with his answer, but using DatePeriod with DateTime is more consistent and makes for more readable code IMHO:-

$oneMonth = new \DateInterval('P1M');
$startDate = \DateTime::createFromFormat('d H:i:s', '1 00:00:00')->sub(new \DateInterval('P4M'));
$period = new \DatePeriod($startDate, $oneMonth, 16);

foreach($period as $date){
    //$date is an instance of \DateTime. I'm just var_dumping it for illustration
    var_dump($date);
}

看到它工作
