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, PHP 8)
getdate — 日付/時刻情報を取得する
説明
timestamp に関する日付情報を有する連想配列を返します。
timestamp が省略されたり、null だった場合、現在のローカルな時間に関する情報を返します。
パラメータ
戻り値
timestamp に関連する情報を連想配列で返します。
返される連想配列の内容は、次のようになります。
| キー | 説明 | 戻り値の例 |
|---|---|---|
"seconds" |
秒。数値。 | 0 から 59 |
"minutes" |
分。数値。 | 0 から 59 |
"hours" |
時。数値 | 0 から 23 |
"mday" |
月単位の日。数値 | 1 から 31 |
"wday" |
曜日。数値。 | 0 (日曜) から 6 (土曜) |
"mon" |
月。数値。 | 1 から 12 |
"year" |
年。4桁の数値。 | 例: 1999 あるいは 2003 |
"yday" |
年単位の日。数値。 | 0 から 365 |
"weekday" |
曜日。フルスペルの文字。 | Sunday から Saturday |
"month" |
月。フルスペルの文字。 | January から December |
0 |
UNIX時（1970年1月1日）からの秒数。 time()の戻り値と同様。 date()でも使用される。 | システムによって違うが、通常は-2147483648 から
2147483647.

?>上の例の出力は、 たとえば以下のようになります。
Array
(
[seconds] => 40
[minutes] => 58
[hours] => 21
[mday] => 17
[wday] => 2
[mon] => 6
[year] => 2003
[yday] => 167
[weekday] => Tuesday
[month] => June
[0] => 1055901520
)

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.
