Andre's code will throw an error. for the following line
$d = $todayh[mday];
$m = $todayh[mon];
$y = $todayh[year];
"Notice : Undefined constant mday ,mon,year"
As is, it was looking for constants called mday, mon, year etc. When it doesn't find such a constant, PHP interprets it as a string.
like any other request it should be wrapped in quotes like this
$d = $todayh['mday'];
$m = $todayh['mon'];
$y = $todayh['year'];
getdate
(PHP 4, PHP 5, PHP 7)
getdate — 날짜/시간 정보를 가져온다
설명
array getdate
([ int
$timestamp = time()
] )
timestamp의 날짜 정보를 포함하는 연관
배열이나, timestamp가 주어지지 않는다면
현재 로컬 시간를 반환합니다.
인수
반환값
timestamp에 관련된 정보를 가진 연관
array를 반환합니다. 반환되는 연관 배열 원소는 다음과 같습니다:
| 키 | 설명 | Example returned values |
|---|---|---|
| "seconds" | 초의 숫자 표현 | 0 부터 59 |
| "minutes" | 분의 숫자 표현 | 0 부터 59 |
| "hours" | 시간의 숫자 표현 | 0 부터 23 |
| "mday" | 일의 숫자 표현 | 1 부터 31 |
| "wday" | 요일의 숫자 표현 | 0 (일요일) 부터 6 (토요일) |
| "mon" | 월의 숫자 표현 | 1 부터 12 |
| "year" | 연도의 숫자표현, 4 자리 | 예시: 1999 또는 2003 |
| "yday" | 연도의 일차 | 0 부터 365 |
| "weekday" | 요일, 완전한 문자 | Sunday 부터 Saturday |
| "month" | 월, 완전한 문자, January 나 March | January 부터 December |
| 0 | 유닉스 Epoch (January 1 1970 00:00:00 GMT)로부터의 초, time()에 의해 반환되는 값과 유사하고, date()에 의해서 사용됩니다. | 시스템에 의존합니다, 일반적으로 -2147483648 부터 2147483647. |
예제
Example #1 getdate() 예제
<?php
$today = getdate();
print_r($today);
?>
위 예제의 출력 예시:
Array
(
[seconds] => 40
[minutes] => 58
[hours] => 21
[mday] => 17
[wday] => 2
[mon] => 6
[year] => 2003
[yday] => 167
[weekday] => Tuesday
[month] => June
[0] => 1055901520
)
참고
- date() - 로컬 날짜/시간을 형식화합니다
- time() - Return current Unix timestamp
- setlocale() - Set locale information

In addition to canby23 at ms19 post:
It's a very bad idea to consider day having 24 hours (86400 secs), because some days have 23, some - 25 hours due to daylight saving changes. Using of mkdate() and strtotime() is always preferred. strtotime() also has a very nice behaviour of datetime manipulations:
<?php
echo strtotime ("+1 day"), "\n";
echo strtotime ("+1 week"), "\n";
echo strtotime ("+1 week 2 days 4 hours 2 seconds"), "\n";
echo strtotime ("next Thursday"), "\n";
echo strtotime ("last Monday"), "\n";
?>

I thought best to show a posseble way to go about bypassing the end month issue where the first day in a new month will have the monday of the week that it falls in - in the old month. Use the numbering of days as the constant and work you way from there.
Example:
<?php
//-----------------------------
$now = time();
$num = date("w");
if ($num == 0)
{ $sub = 6; }
else { $sub = ($num-1); }
$WeekMon = mktime(0, 0, 0, date("m", $now) , date("d", $now)-$sub, date("Y", $now)); //monday week begin calculation
$todayh = getdate($WeekMon); //monday week begin reconvert
$d = $todayh[mday];
$m = $todayh[mon];
$y = $todayh[year];
echo "$d-$m-$y"; //getdate converted day
?>
Allot less code makes everyone happy..

another gmgetdate that is a little faster/suscint (no loops).
<?php
function gmgetdate2($ts = null){
$k = array('seconds','minutes','hours','mday',
'wday','mon','year','yday','weekday','month',0);
return(array_combine($k,split(":",
gmdate('s:i:G:j:w:n:Y:z:l:F:U',is_null($ts)?time():$ts))));
}
?>

It's worth noting that this is local time, not UTC/GMT - gmgetdate doesn't exist :(.
The most logical way to handle date arithmetic without hitting DST problems is to work in UTC...
<?php
function add_days($my_date,$numdays) {
$date_t = strtotime($my_date.' UTC');
return gmdate('Y-m-d',$date_t + ($numdays*86400));
}
?>
[it's even faster if you use gmmktime instead of strtotime]

Here is another gmgetdate that is a little faster/suscint (no loops).
<?php
function gmgetdate2($ts = null){
$k = array('seconds','minutes','hours','mday',
'wday','mon','year','yday','weekday','month',0);
return(array_combine($k,split(":",
gmdate('s:i:G:j:w:n:Y:z:l:F:U',is_null($ts)?time():$ts))));
}
?>
It also returns the values in the same order as getdate.
