date
A function/method to calculate the next workday, taking into account US federal holidays:
<?php
function getNextWorkDayTime($date=null)
{
$time = is_string($date) ? strtotime($date) : (is_int($date) ? $date : time());
$y = date('Y', $time);
// calculate federal holidays
$holidays = array();
// month/day (jan 1st). iteration/wday/month (3rd monday in january)
$hdata = array('1/1'/*newyr*/, '7/4'/*jul4*/, '11/11'/*vet*/, '12/25'/*xmas*/, '3/1/1'/*mlk*/, '3/1/2'/*pres*/, '5/1/5'/*memo*/, '1/1/9'/*labor*/, '2/1/10'/*col*/, '4/4/11'/*thanks*/);
foreach ($hdata as $h1) {
$h = explode('/', $h1);
if (sizeof($h)==2) { // by date
$htime = mktime(0, 0, 0, $h[0], $h[1], $y); // time of holiday
$w = date('w', $htime); // get weekday of holiday
$htime += $w==0 ? 86400 : ($w==6 ? -86400 : 0); // if weekend, adjust
} else { // by weekday
$htime = mktime(0, 0, 0, $h[2], 1, $y); // get 1st day of month
$w = date('w', $htime); // weekday of first day of month
$d = 1+($h[1]-$w+7)%7; // get to the 1st weekday
for ($t=$htime, $i=1; $i<=$h[0]; $i++, $d+=7) { // iterate to nth weekday
$t = mktime(0, 0, 0, $h[2], $d, $y); // get next weekday
if (date('n', $t)>$h[2]) break; // check that it's still in the same month
$htime = $t; // valid
}
}
$holidays[] = $htime; // save the holiday
}
for ($i=0; $i<5; $i++, $time+=86400) { // 5 days should be enough to get to workday
if (in_array(date('w', $time), array(0, 6))) continue; // skip weekends
foreach ($holidays as $h) { // iterate through holidays
if ($time>=$h && $time<=$h+86400) continue 2; // skip holidays
}
break; // found the workday
}
return $time;

getdate
(PHP 4, PHP 5)
getdate — Tarih/zaman bilgisi getirir
Açıklama
array getdate
([ int $zaman_damgası = time()
] )
Değiştirgeyle çağrılmışsa zaman_damgası 'na karşılık olan tarih bilgisini bir ilişkisel dizi olarak döndürür. Değiştirgesiz çağrılmışsa dönen değer o anın yerel zamanına göre olur.
Değiştirgeler
- zaman_damgası
-
Seçimlik zaman_damgası değiştirgesi integer türünde bir Unix zaman damgası olup belirtilmediği takdirde yerel zaman kullanılır. Başka bir deyişle, time() işlevinden dönen değer öntanımlıdır.
Dönen Değerler
zaman_damgası 'na karşılık olan tarih bilgisini bir ilişkisel dizi olarak döndürür. İlişkisel dizide döndürülen öğeler aşağıdaki gibidir:
| Anahtar | Açıklama | Örnek dönüş değerleri |
|---|---|---|
| "seconds" | Saniyelerin sayısal gösterimi | 0'dan 59'a kadar |
| "minutes" | Dakikaların sayısal gösterimi | 0'dan 59'a kadar |
| "hours" | Saatlerin sayılsal gösterimi | 0'dan 23'e kadar |
| "mday" | Ayın günlerinin sayısal gösterimi | 1'den 31'e kadar |
| "wday" | Haftanın günlerinin sayılsal gösterimi | (Pazar için) 0'dan (Cumartesi için) 6'ya kadar |
| "mon" | Ayın sayısal gösterimi | 1 'den 12'ye kadar |
| "year" | Yılın 4 haneli sayısal tam gösterimi | Örnek: 1999 ya da 2003 gibi |
| "yday" | Yılın gününün sayısal gösterimi | 0'dan 365'e kadar |
| "weekday" | Haftanın gününün metinsel tam gösterimi | Sunday'dan Saturday'ye |
| "month" | Ayın metinsel tam gösterimi, Ocak ya da Mart gibi | January'dan December'a kadar |
| 0 | Saniyeler, Unix Zaman Başlangıcından itibaren, time() işlevi tarafından döndürülen ve date() işleviyle kullanılan değerlerle benzerdir. | Sisteme Bağımlı, genellikle -2147483648 ile 2147483647 arasında. |
Örnekler
Örnek 1 - getdate() örneği
<?php
$bugun = getdate();
print_r($bugun);
?>
Yukarıdaki örnek şuna benzer bir çıktı üretir:
Array
(
[seconds] => 40
[minutes] => 58
[hours] => 21
[mday] => 17
[wday] => 2
[mon] => 6
[year] => 2003
[yday] => 167
[weekday] => Salı
[month] => Haziran
[0] => 1055901520
)

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.

I couldn't get the last 2 examples of gmgetdate() to work, so here's a modification that did work for me that behaves exactly like getdate() :
<?php
function gmgetdate($timestamp = null) {
if (is_null($timestamp)) { $timestamp = time(); }
$dateParts = array(
'mday' => 'j',
'wday' => 'w',
'yday' => 'z',
'mon' => 'n',
'year' => 'Y',
'hours' => 'G',
'minutes' => 'i',
'seconds' => 's',
'weekday' => 'l',
'month' => 'F',
0 => 'U'
);
while (list($part, $format) = each($dateParts)) {
$GMdateParts[$part] = gmdate($format, $timestamp);
}
return $GMdateParts;
}
?>

Simplier version of gmgetdate
function gmgetdate($timestamp = null)
{
if ($timestamp) return getdate($timestamp);
else return getdate(time());
}
Note: A unix timestamp is always represented in GMT (or more correctly UCT)

For those who want the gmgetdate function that matches the behaviour of getdate:
<?php
function gmgetdate($timestamp = null) {
if (is_null($timestamp)) { $timestamp = time(); }
$dateParts = array(
'mday' => 'j',
'wday' => 'w',
'yday' => 'z',
'mon' => 'n',
'year' => 'Y',
'hours' => 'G',
'minutes' => 'i',
'seconds' => 's',
'weekday' => 'l',
'month' => 'F',
0 => 'U'
);
while (list(, $value) = each($dateParts)) {
$value = gmdate($value, $timestamp);
if (is_numeric($value)) { $value = (int)$value; }
}
return $dateParts;
}
?>

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]

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..

A nice little function I wrote to determine what number occurrence weekday it is of the month for a given timestamp. (I.e. 2nd Friday, or the 3rd Thursday)
Eg: print_r(getWeekdayOccurrence(mktime(0, 0, 0, 12, 1, 2006)));
Outputs: Array ( [0] => 1 [1] => Friday ) [The first friday]
Eg. print_r(getWeekdayOccurrence(mktime(0, 0, 0, 8, 17, 2009)));
Outputs: Array ( [0] => 3 [1] => Monday ) [The third Monday]
<?php
function getWeekdayOccurrence($time) {
$month = intval(date("m", $time)); $day = intval(date("d", $time));
for ($i = 0; $i < 7; $i++) {
$days[] = date("l", mktime(0, 0, 0, $month, ($i+1), date("Y", $time)));
}
$posd = array_search(date("l", $time), $days);
$posdm = array_search($days[0], $days) - $posd; /
return array((($day+$posdm+6)/7), $days[$posd]);
}

getdate does not convert week numbers. this function relies on strftime to find a timestamp that falls on the monday of specified year and ISO week:
<?php function getisomonday($year, $week) {
# check input
$year = min ($year, 2038); $year = max ($year, 1970);
$week = min ($week, 53); $week = max ($week, 1);
# make a guess
$monday = mktime (1,1,1,1,7*$week,$year);
# count down to week
while (strftime('%V', $monday) != $week)
$monday -= 60*60*24*7;
# count down to monday
while (strftime('%u', $monday) != 1)
$monday -= 60*60*24;
# got it
return $monday;
} ?>

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";
