date
(PHP 4, PHP 5)
date — Formatiert ein(e) angegebene(s) Zeit/Datum
Beschreibung:
string date
( string $Format
[, int $Timestamp
] )
Gibt einen formatierten String anhand eines vorzugebenden Musters zurück. Dabei wird entweder der angegebene Timestamp oder die gegenwärtige lokale Zeit berücksichtigt, wenn kein Timestamp angegegeben wird. Mit anderen Worten ausgedrückt: der Parameter Timestamp ist optional und falls dieser nicht angegeben wird, wird der Wert der Funktion time() angenommen.
Hinweis: Der gültige Bereich eines Timestamp liegt typischerweise zwischen Fri, 13 Dec 1901 20:45:54 GMT und Tue, 19 Jan 2038 03:14:07 GMT. (Das entspricht den minimalen und maximalen Werten für einen vorzeichenbehafteten 32-Bit Integer). Unter Windows-Betriebssytemen ist dieser Bereich auf 01-01-1970 bis 19-01-2038 beschränkt.
Hinweis: Um einen Timestamp aus aus einem Datums-String zu erzeugen, können Sie die Funktion strtotime() benutzen. Zusätzlich bieten einige Datenbanken Funktionen, um Ihre Datumsfromate in Timestamps umzuwandeln (wie zum Beispiel MySQL's » UNIX_TIMESTAMP Funktion.

Beispiel #1 date() Beispiel
<?php
// Gibt etwas ähnliches zu Wednesday aus
echo date("l");
// Gibt etwas ähnliches aus wie: Wednesday 15th of January 2003 05:51:38 AM
echo date("l dS of F Y h:i:s A");
// Ausgabe: July 1, 2000 ist ein Saturday
echo "July 1, 2000 ist ein " . date("l", mktime(0, 0, 0, 7, 1, 2000));
?>
Möchten Sie verhindern, dass ein erkanntes Zeichen im Formatstring ersetzt wird, sollten Sie dieses Zeichen mit einem vorangestellten Backslash escapen. Ist das Zeichen mit dem Backslash bereits eine spezielle Zeichenfolge, müssen Sie diesen Backslash ebenso escapen.
Beispiel #2 Escaping von Zeichen in date()
// gibt etwas ähnliches aus wie 'Wednesday the 15th'
echo date("l \\t\h\e jS");
Es ist möglich, date() und mktime() gleichzeitig zu verwenden, um Datumsangaben in der Zukunft/Vergangenheit zu bestimmen.
Beispiel #3 date() und mktime() Beispiele
<?php
$morgen = mktime(0, 0, 0, date("m") , date("d")+1, date("Y"));
$letztermonat = mktime(0, 0, 0, date("m")-1, date("d"), date("Y"));
$naechstesjahr = mktime(0, 0, 0, date("m"), date("d"), date("Y")+1);
?>
Hinweis: Dieses Vorgehen kann zu verlässlicheren Ergebnissen führen, als simples addieren oder subtrahieren der Anzahl von Sekunden in Tagen oder Monaten zu einem Timestamp, da Sommer- und Winterzeit berücksichtigt werden.
Es folgen einige Beispiele zur date() Formatierung. Beachten Sie, dass Sie alle anderen Zeichen escapen sollten, da alle Zeichen, die im Augenblick eine spezielle Bedeutung haben, unerwünschte Resultate liefern. Bei allen weiteren Zeichen kann es durchaus möglich sein, dass diesen in zukünftigen PHP-Versionen eine Bedeutung zukommt. Beim escapen sollten Sie darauf achten einfache Anführungszeichen zu benutzen, damit Zeichenfolgen wie zum Beispiel \n zu keinem Zeilenumbruch führen.
Beispiel #4 date() Formatierungen
<?php
// Angenommen heute ist March 10th, 2001, 5:16:18 pm
$today = date("F j, Y, g:i a"); // March 10, 2001, 5:16 pm
$today = date("m.d.y"); // 03.10.01
$today = date("j, n, Y"); // 10, 3, 2001
$today = date("Ymd"); // 20010310
$today = date('h-i-s, j-m-y, it is w Day z '); // 05-16-17, 10-03-01, 1631 1618 6 Fripm01
$today = date('\i\t \i\s \t\h\e jS \d\a\y.'); // It is the 10th day.
$today = date("D M j G:i:s T Y"); // Sat Mar 10 15:16:08 MST 2001
$today = date('H:m:s \m \i\s\ \m\o\n\t\h'); // 17:03:17 m is month
$today = date("H:i:s"); // 17:16:17
?>
Um Datumsangaben in anderen Sprach-/Zeitzonen-Formaten auszugeben, sollten Sie die Funktionen setlocale() und strftime() benutzen.

here is the simpliest way to get the start and end date of the week;
<?php
$sdate=date('c',strtotime(date('Y')."W".date('W')."0"));
$edate=date('c',strtotime(date('Y')."W".date('W')."7"));
?>
the format is for the string in strtotime is;
2008W200
this stands for year - 2008, constant never changes - W, week number of the year - 20, day of the week - 0 for sunday, 1 for monday, etc....
so 2008W200 stands for the sunday of the 20th week of 2008.
This will only work in php 5 or better

All novices must be very carefull when working with timestamps as second values.
From first glance it looks like date("Y-m-d H:i:s",TIMESTAMP) will return correct date, based on "how much seconds gone from 1970".
But here is the feature, it'll be corrected time, according to LOCAL timezone.
So if you take a 25200 as timestamp (10 hours),
then on one server you'll get
1970-01-01 08:00:00
and on other server you'll get
1970-01-01 09:00:00
and so on.
Though you could expect 1970-01-01 10:00:00 in all cases, because if 25200 seconds gone from 1970-01-01 00:00:00 it obviously have to be 1970-01-01 10:00:00
I spend today 3 hours to correct scripts which were created with such error by previous programmer, so please, guys, don't make me work like this and remember about conversation to LOCAL time.

Try this for finding the difference in days between 2 dates/datetimes... take note though, date_parse requires PHP version 5.1.3 or higher.
<?php
/**
* Finds the difference in days between two calendar dates.
*
* @param Date $startDate
* @param Date $endDate
* @return Int
*/
function dateDiff($startDate, $endDate)
{
// Parse dates for conversion
$startArry = date_parse($startDate);
$endArry = date_parse($endDate);
// Convert dates to Julian Days
$start_date = gregoriantojd($startArry["month"], $startArry["day"], $startArry["year"]);
$end_date = gregoriantojd($endArry["month"], $endArry["day"], $endArry["year"]);
// Return difference
return round(($end_date - $start_date), 0);
}

if you want to get the number of month
between two dates
you can use this function:
<?php
/*
$start = "YYYYMM" ;
$stop = "YYYYMM" ;
*/
function getNumMonth($start,$stop) {
$aSta = substr($start,0,4) ;
$aSto = substr($stop,0,4) ;
$mSta = substr($start,4,2) ;
$mSto = substr($stop,4,2) ;
if($aSta == $aSto) {
return $mSto-$mSta+1 ;
} else {
if(($aSto-$aSta) == 1) {
return 12-$mSta+$mSto+1 ;
} else {
return (12-$mSta+$mSto+1)+($aSto-$aSta-1)*12;
}
}
}

to get the date of the monday from a week these function is useful:
<?php
/* Get First Calendar Week of Year x*/
function firstkw($jahr)
{
$erster = mktime(0,0,0,1,1,$jahr);
$wtag = date('w',$erster);
if ($wtag <= 4) {
/**
* Donnerstag oder kleiner: auf den Montag zurückrechnen.
*/
$montag = mktime(0,0,0,1,1-($wtag-1),$jahr);
} else {
/**
* auf den Montag nach vorne rechnen.
*/
$montag = mktime(0,0,0,1,1+(7-$wtag+1),$jahr);
}
return $montag;
}
/*GET timestamp of monday of month x*/
function mondaykw($kwtime)
{
$firstmonday =$this->firstkw(date("Y", $kwtime));
$mon_monat = date('m',$firstmonday);
$mon_jahr = date('Y',$firstmonday);
$mon_tage = date('d',$firstmonday);

Assuming a week starts on Monday. To calculate the week number of the current date starting from a specified date, use this function:
<?php
function weekcounter($start_date)
{
$start_date = strtotime($start_date);
$today = strtotime(date('d-m-Y'));
$week = 1;
while($start_date < $today) {
$start_date = strtotime('next Monday', $start_date);
$week++;
}
return $week;
}
// Example:
//now = 14-07-2008
echo weekcounter('01-07-2008'); //prints 3
echo weekcounter('01-06-2008'); //prints 8 instead of 7; because 1st jun is a Sunday so it is week 1 and 2nd june is week 2. Feel free to tweak.

Quick function for returning the names of the next 7 days of the week starting with today.
Returns an array that can be formatted to your liking.
<?php
/**
* Returns array of next 7 days starting with today
*
*/
function next_7_days() {
// create array of day names. You can change these to whatever you want
$days = array(
'Monday',
'Tuesday',
'Wednesday',
'Thursday',
'Friday',
'Saturday',
'Sunday');
$today = date('N');
for ($i=1;$i<$today;$i++) {
// take the first element off the array
$shift = array_shift($days);
// ... and add it to the end of the array
array_push($days,$shift);
}
// returns the sorted array
return $days;
}
?>
It basically takes an array starting with Monday and shifts each day to the end of the array until the first element in the array is today.

Doing $w-- for months ending on Sat won't hurt (i.e. if you're counting weeks as is the case below), but halocastle's code is perfectly fine as is and quite fast. He/she uses $w as a key for the $weeks array. "Halo" does this BEFORE $w++, so $w-- is superfluous as the loop has already ended. For May, 2008, I get 5 weeks as expected...
Array
(
[1] => Array
(
[4] => 1
[5] => 2
[6] => 3
)
[2] => Array
(
[0] => 4
[1] => 5

[1] => 26
[2] => 27
[3] => 28
[4] => 29
[5] => 30
[6] => 31
)
)
I guess the one pit-fall of the code is if you overlap months, say the following year, then $m-- makes perfect since...I think (haven't gotten that far...yet).
I modified "Halo's" code to include months, too (this is from a snippet that produces a three month calendar, hence the outer $months loop, omitted here).
<?php
$m = date('m');
$Y = date('Y');
// for() {months loop omitted
$var_date = mktime(0, 0, 0, $m, 1, $Y);
$month_name = date('F', $var_date);
$months[$month_name]['DAYS'] = date('t', $var_date);
$months[$month_name]['FIRST_DAY'] = date('w', $var_date);
//}
foreach($months as $month => $key) {
$weeks = array();
for($i = 1, $j = $key['FIRST_DAY'], $w = 1;$i <= $key['DAYS'];$i++) {
$weeks[$w][$j] = $i;
$j++;
if($j == 7) {
$j = 0;
$w++;
}
}
$months[$month]['WEEKS'] = $weeks;
}
?>

for($i = date('Y'); $i >= 1970; $i--){
if($i == date('Y', $timestamp)){

}else{
$out .= '<option value="'.$i.'">'.$i.'</option>';

}
$out .= "</select>";
return $out;

?>
Usage is simple:
<?php
echo chooseDate(); // Will select current date
echo chooseDate(1149566400); // Will select June 6th, 2006
?>

@anonymous (12-Jun-2008 08:45):
date("t") returns the last day of the month, not the last working day of the month.
A cleaner example would be as follows:
<?php
function lastworkingday($date)
{
for($lastday=mktime(0,0,0,date("m",$date),
date("t",$date),date("Y",$date));
date("w",$lastday)==0 || date("w",$lastday)==6;
$lastday-=60*60*24);
return date("j",$lastday);
}
?>

to get the week of the month simply use:
ceil( date("j") / 7 );

I made a small code to get the last working day of the month:
<?php
$times = strtotime(date("Y")."-".date("m")."-".date("t"));
for ($lastworkingday=0;$lastworkingday==0;$times-=86400)
if (date("w",$times)!=0 && date("w",$times)!=6) $lastworkingday = date("j",$times);
print $lastworkingday;

Found this helpful when converting unix dates for use with the ical file format.
<?php
// Converts a unix timestamp to iCal format (UTC) - if no timezone is
// specified then it presumes the uStamp is already in UTC format.
// tzone must be in decimal such as 1hr 45mins would be 1.75, behind
// times should be represented as negative decimals 10hours behind
// would be -10
function unixToiCal($uStamp = 0, $tzone = 0.0) {
$uStampUTC = $uStamp + ($tzone * 3600);
$stamp = date("Ymd\THis\Z", $uStampUTC);
return $stamp;
}
