基於一年的月份的第一個和最後一個日期的列表

Question

我想創建一個函數，輸出一個月份的第一個日期和月份的最後一個日期的列表，根據年份給出一個論點。

function first_and_last_dates_of_month($year){ 
//code 
} 

first_and_last_dates_of_month(2014); 

我想有輸出財產以後這樣的：

2014-01-01 
2014-01-31 
2014-02-01 
2014-02-28 
2014-03-01 
2014-03-31 
2014-04-01 
2014-04-30 
2014-05-01 
2014-05-31 
2014-06-01 
2014-06-30 
2014-07-01 
2014-07-31 
2014-08-01 
2014-08-31 
2014-09-01 
2014-09-30 
2014-10-01 
2014-10-31 
2014-11-01 
2014-11-30 
2014-12-01 
2014-12-31 

Answer 1

希望它會幫助你：

function first_and_last_dates_of_month($year=2014){ 
    for ($i=1; $i<=12; $i++) { 
     $timestamp = strtotime(date("$i/01/y")); 
     echo "<br/>"; 
     echo $first_second = date('Y-m-01', $timestamp); 
     echo "<br/>"; 
     echo $last_second = date('Y-m-t', $timestamp); 
    } 
} 

first_and_last_dates_of_month(2014); 

Answer 2

這也是一種可能性。

$year = date('Y'); 
$array = array(
    1 => ''.$year.'-01-01', 
    2 => ''.$year.'-01-'.cal_days_in_month(CAL_GREGORIAN, 1, $year), 
    3 => ''.$year.'-02-01', 
    4 => ''.$year.'-02-'.cal_days_in_month(CAL_GREGORIAN, 2, $year), 
    5 => ''.$year.'-03-01', 
    6 => ''.$year.'-03-'.cal_days_in_month(CAL_GREGORIAN, 3, $year), 
    7 => ''.$year.'-04-01', 
    8 => ''.$year.'-04-'.cal_days_in_month(CAL_GREGORIAN, 4, $year), 
    9 => ''.$year.'-05-01', 
    10 => ''.$year.'-05-'.cal_days_in_month(CAL_GREGORIAN, 5, $year), 
    11 => ''.$year.'-06-01', 
    12 => ''.$year.'-06-'.cal_days_in_month(CAL_GREGORIAN, 6, $year), 
    13 => ''.$year.'-07-01', 
    14 => ''.$year.'-07-'.cal_days_in_month(CAL_GREGORIAN, 7, $year), 
    15 => ''.$year.'-08-01', 
    16 => ''.$year.'-08-'.cal_days_in_month(CAL_GREGORIAN, 8, $year), 
    17 => ''.$year.'-09-01', 
    18 => ''.$year.'-09-'.cal_days_in_month(CAL_GREGORIAN, 9, $year), 
    19 => ''.$year.'-10-01', 
    20 => ''.$year.'-10-'.cal_days_in_month(CAL_GREGORIAN, 10, $year), 
    21 => ''.$year.'-11-01', 
    22 => ''.$year.'-11-'.cal_days_in_month(CAL_GREGORIAN, 11, $year), 
    23 => ''.$year.'-12-01', 
    24 => ''.$year.'-12-'.cal_days_in_month(CAL_GREGORIAN, 12, $year)); 
var_dump($array);
