[ PHP ] – 列出指定 日期範圍 內所有日期

最近在做統計報表的時候要用到列出某個 日期範圍 的時間資料，上網找到相關程式，自已小改一下因為我需要包含最後一天的日期。

$dd= date_range('2020-01-01','2020-01-31');
print_r($dd);
function date_range($first, $last)
{
    $last=date('Y-m-d', strtotime($last.'+1 day'));
    $period = new DatePeriod(
        new DateTime($first),
        new DateInterval('P1D'),
        new DateTime($last)
    );
    foreach ($period as $date)
        $dates[] = 'log_'.$date->format('Y_m_d');
    return $dates;
}

顯示結果：
2020-02-01Array ( [0] => log_2020_01_01 [1] => log_2020_01_02 [2] => log_2020_01_03 [3] => log_2020_01_04 [4] => log_2020_01_05 [5] => log_2020_01_06 [6] => log_2020_01_07 [7] => log_2020_01_08 [8] => log_2020_01_09 [9] => log_2020_01_10 [10] => log_2020_01_11 [11] => log_2020_01_12 [12] => log_2020_01_13 [13] => log_2020_01_14 [14] => log_2020_01_15 [15] => log_2020_01_16 [16] => log_2020_01_17 [17] => log_2020_01_18 [18] => log_2020_01_19 [19] => log_2020_01_20 [20] => log_2020_01_21 [21] => log_2020_01_22 [22] => log_2020_01_23 [23] => log_2020_01_24 [24] => log_2020_01_25 [25] => log_2020_01_26 [26] => log_2020_01_27 [27] => log_2020_01_28 [28] => log_2020_01_29 [29] => log_2020_01_30 [30] => log_2020_01_31 )
