原文:https://blog.csdn.net/sqlquan/article/details/87795918

1、封装

/**
 * 获取一个日期范围内的日期
 * @param int $interval 日期范围
 * @param string $type 取值类型,-:获取之前日期;+:获取之后的日期
 * @return array
 */
protected function getDateInterval(int $interval,string $type) :array
{
    $dateArr = [];
    for ($i = $interval - 1; $i >= 0; $i--) {
        array_push($dateArr, date('Y-m-d', strtotime("{$type}{$i} day")));
    }
    if($type=='+')$dateArr=array_reverse($dateArr);
    return $dateArr;
}

2、调用

$rs = $this->getDateInterval(14,'-');
print_r($rs);
array:14 [
  0 => "2022-07-13"
  1 => "2022-07-14"
  2 => "2022-07-15"
  3 => "2022-07-16"
  4 => "2022-07-17"
  5 => "2022-07-18"
  6 => "2022-07-19"
  7 => "2022-07-20"
  8 => "2022-07-21"
  9 => "2022-07-22"
  10 => "2022-07-23"
  11 => "2022-07-24"
  12 => "2022-07-25"
  13 => "2022-07-26"
]


$rs2 = $this->getDateInterval(14,'+');
print_r($rs2);
array:14 [
  0 => "2022-07-26"
