Описание

string date ( string format [, int timestamp] )

Возвращает время, отформатированное в соответствии с аргументом format, используя метку времени, заданную аргументом timestamp или текущее системное время, если timestamp не задан. Другими словами, timestamp является необязательным и по умолчанию равен значению, возвращаемому функцией time().

Замечание: Для большинства систем допустимыми являются даты с 13 декабря 1901, 20:45:54 GMT по 19 января 2038, 03:14:07 GMT. (Эти даты соответствуют минимальному и максимальному значению 32-битового целого со знаком). Для Windows допустимы даты с 01-01-1970 по 19-01-2038.

Замечание: Для получения метки времени из строкового представления даты можно использовать функцию strtotime(). Кроме того, некоторые базы данных имеют собственные функции для преобразования внутреннего представления даты в метку времени (напрмер, функция MySQL UNIX_TIMESTAMP).

Таблица 1. В параметре format распознаются следующие символы

Символ в строке `format`	Описание	Пример возвращаемого значения
`a`	Ante meridiem или Post meridiem в нижнем регистре	`am` или `pm`
`A`	Ante meridiem или Post meridiem в верхнем регистре	`AM` или `PM`
`B`	Время в стадарте Swatch Internet	От `000` до `999`
`c`	Дата в формате ISO 8601 (добавлено в PHP 5)	2004-02-12T15:19:21+00:00
`d`	День месяца, 2 цифры с ведущими нулями	от `01` до `31`
`D`	Сокращенное наименование дня недели, 3 символа	от `Mon` до `Sun`
`F`	Полное наименование месяца, например January или March	от `January` до `December`
`g`	Часы в 12-часовом формате без ведущих нулей	От `1` до `12`
`G`	Часы в 24-часовом формате без ведущих нулей	От `0` до `23`
`h`	Часы в 12-часовом формате с ведущими нулями	От `01` до `12`
`H`	Часы в 24-часовом формате с ведущими нулями	От `00` до `23`
`i`	Минуты с ведущими нулями	`00` to `59`
`I` (заглавная i)	Признак летнего времени	`1`, если дата соответствует летнему времени, иначе `0` otherwise.
`j`	День месяца без ведущих нулей	От `1` до `31`
`l` (строчная 'L')	Полное наименование дня недели	От `Sunday` до `Saturday`
`L`	Признак високосного года	`1`, если год високосный, иначе `0`.
`m`	Порядковый номер месяца с ведущими нулями	От `01` до `12`
`M`	Сокращенное наименование месяца, 3 символа	От `Jan` до `Dec`
`n`	Порядковый номер месяца без ведущих нулей	От `1` до `12`
`O`	Разница с временем по Гринвичу в часах	Например: `+0200`
`r`	Дата в формате RFC 2822	Например: `Thu, 21 Dec 2000 16:01:07 +0200`
`s`	Секунды с ведущими нулями	От `00` до `59`
`S`	Английский суффикс порядкового числительного дня месяца, 2 символа	`st`, `nd`, `rd` или `th`. Применяется совместно с `j`
`t`	Количество дней в месяце	От `28` до `31`
`T`	Временная зона на сервере	Примеры: `EST`, `MDT` ...
`U`	Количество секунд, прошедших с начала Эпохи Unix (The Unix Epoch, 1 января 1970, 00:00:00 GMT)	См. также time()
`w`	Порядковый номер дня недели	От `0` (воскресенье) до `6` (суббота)
`W`	Порядковый номер недели года по ISO-8601, первый день недели - понедельник (добавлено в PHP 4.1.0)	Например: `42` (42-я неделя года)
`Y`	Порядковый номер года, 4 цифры	Примеры: `1999`, `2003`
`y`	Номер года, 2 цифры	Примеры: `99`, `03`
`z`	Порядковый номер дня в году (нумерация с 0)	От `0` до `365`
`Z`	Смещение временной зоны в секундах. Для временных зон западнее UTC это отрицательное число, восточнее UTC - положительное.	От `-43200` до `43200`

Любые другие символы, встреченные в строке format, будут выведены в результирующую строку без изменений. Z всегда возвращает 0 при использовании gmdate().

Пример 1. Примеры использования функции date()

<?php // вывод дня недели, например Wednesday echo date("l"); // вывод даты в формате: Wednesday 15th of January 2003 05:51:38 AM echo date("l dS of F Y h:i:s A"); // вывод: July 1, 2000 is on a Saturday echo "July 1, 2000 is on a " . date("l", mktime(0, 0, 0, 7, 1, 2000)); ?>

Избежать распознавания символа как форматирующего можно, если экранировать этот символ с помощью \ Если в сочетании с \ символ являееся специальным (например, \t), следует добавлять еще один \.
Пример 2. Экранирование символов в функции date()

<?php // вывод: Wednesday the 15th echo date("l \\t\h\e jS"); ?>

Функции date() и mktime() для вывода прошедших и будущих дат.
Пример 3. date() и mktime() example

<?php $tomorrow = mktime(0, 0, 0, date("m") , date("d")+1, date("Y")); $lastmonth = mktime(0, 0, 0, date("m")-1, date("d"), date("Y")); $nextyear = mktime(0, 0, 0, date("m"), date("d"), date("Y")+1); ?>

Замечание: Этот метод более надежен, чем вычитание и прибавление секунд к метке времени, так как mktime() учитывает любые неоднозначности в датах (переход на летнее/зимнее время и др.).

Приведем еще несколько примеров использования функции date(). Помните, что следует экранировать все символы, которые вы хотите видеть в результате работы функции без изменений. Это относится и к символам, которые в текущей версии PHP не распознаются как специальные, так как этим символам может быть назначено значение в следующих версиях. Используйте одинарные кавычки для предотвращения преобразования \n в перевод строки.
Пример 4. Форматирование с использованием date()

<?php // Предположим, что текущая дата 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 ?>

Для форматирования дат на других языках используйте функции setlocale() и strftime().

I was looking for a function to find the week range for a particular week. But now I have developed by own. This function takes three arguments all optional 

1. Week - This value ranges from 1- 52 or 53. It needs a correct value. If no value is provided, it then uses the current week.

2. Year - If none is provided, then the current year.

3. Format - defaults to d/M/Y



It returns an array containing the 'start date' and the 'end date'



Imp. Week starts from Sunday.



function getWeekDateRange($week="",$year="",$format="d/M/Y"){

    if($year=="" || !is_numeric($year))

        $year=date("Y");

    if($week=="" || !is_numeric($week))

        $week=date("W");        

        

    $week--;        

  $first_day=date("w",mktime(0,0,0,1,1,$year));

    $first_day_tstamp=mktime(0,0,0,1,1,$year);    

    $first_sunday=($first_day==0?0:(6-$first_day+1));

    $first_sunday_tstamp=$first_sunday*24*3600+$first_day_tstamp;    

        

    if($first_sunday!=0){

        $week_cal=$week-1;

    }else{

        $week_cal=$week;

    }    

    

    $tw_start_tstamp=$first_sunday_tstamp+$week_cal*7*24*3600;

    $tw_end_tstamp=$first_sunday_tstamp+($week_cal+1)*7*24*3600-1;

    

    $yy=date("Y",$tw_end_tstamp);

    if($yy>$year)

        $tw_end_tstamp=mktime(23,59,59,12,31,$year);    

    if($week==0 && $first_sunday!=0){

        $tw_start_tstamp=$first_day_tstamp;

        $tw_end_tstamp=$first_sunday_tstamp-1;        

    }    

    

    $start_date=date($format,$tw_start_tstamp);

    $end_date=date($format,$tw_end_tstamp);

    

    return array($start_date,$end_date);

}

Hello, these notes have been very helpful and help me solve the following problem.



I have a db with scheduled items that contain a start date, a day to occur on and how many weeks from the next closest day to happen again.  I wrote the following script to do the following

1. Accept : starting date, the current date, the number of weeks between occurances and the day of the week it is to occur on.

2. Find the closest future day of the week argument from the start date.

3. Find out when the next time the item should happen via the weeks inbetween and the closest day of the week to the start date.



The result could be compared with your current date to trigger your periodical item or simply to find out when the next occurances will happen.



// $startDate:Date

// $todayDate:Date

// $weeks:Int - number of weeks in between

// $wantDay:String - full day of the week

function getWeekPeriodDate($startDate,$todayDate,$weeks,$wantDay){

  $startDate = date("Y-m-d", strtotime("next $wantDay" ,strtotime($startDate))); 

  $dayDiff = round((strtotime($startDate)-strtotime($todayDate))/(24*60*60),0);

  $weekPeriodDiff = abs(round($dayDiff/7/$weeks)*$weeks);

  return date("Y-m-d",strtotime($startDate . " + " . $weekPeriodDiff . " weeks"));

}



Usage :getWeekPeriodDate("2006-July-1","2007-Nov-5",8,"Tuesday")

returns : 2007-11-20 (which is the next Tuesday based on 8 week periods since the next Tuesday closest to the start date)

Just a quick note on Josh L's implementation, switch doesn't pick up differences of '0' (or false) so if you are sending an email out at the same time as posting something, it will give you just a date (in the default) rather than a cute string. So, just add a catch at the top like 



<?php



if($diff === 0) { 

    return "just now"; 

} else {

 <do everything else>

}



?>



otherwise thanks josh for a v useful function :)

If you have a unix time stamp value in your DB that you would like to see the elapsed time for this might save you some time:



<?php

if(mysql_result($result, 0, "Time_Stamp")){

$Now=strtotime(date('Y-m-d H:i:s'));

$Action=strtotime(mysql_result($result, 0, "Time_Stamp"));



## Calculate time past since status change

$dateDiff = $Now - $Action;

$Days = floor($dateDiff/(60*60*24));

$Hours = floor(($dateDiff-($Days*60*60*24))/(60*60));

$Minutes = floor(($dateDiff-($Days*60*60*24)-($Hours*60*60))/60);

$Seconds = floor($dateDiff-($Days*60*60*24)-($Hours*60*60)-($Minutes*60));



## Display in unix like time stamp format

echo str_pad($Days, 2, "0", STR_PAD_LEFT)." ".str_pad($Hours, 2, "0", STR_PAD_LEFT).":".str_pad($Minutes, 2, "0", STR_PAD_LEFT).":".str_pad($Seconds, 2, "0", STR_PAD_LEFT);} ?>

I was searching to change order within the date.

Instead of YYYY-mm-dd, to get different order.

One query is simple:

 "SELECT place, DATE_FORMAT(event_date,'%d.%m.%Y.') AS event_date FROM  table";



The date comes out as d.m.YYYY. as this is usual in my country.

If you're wanting to increment a date, add twenty-FIVE hours (yes, one day per year may last 25 hours...), and the additional hour won't impact other days, as it's converted to a Y-m-d string:



$date=date('Y-m-d', strtotime($date)+(25*3600));



Try this for october 28, 2007...

I made a minor modification to wes.wysoft.com's "nth day of the month" function. I was attempting to convert Windows registry TIME_ZONE_INFORMATION structs to PHP dates to do timezone + DST conversions, and the registry entries don't seem to be quite right - for GMT, the correct end of DST is "the last Sunday in October", but the windows registry stores it as "the 5th Sunday in October"... but in 2007 there are only 4 Sundays! To protect from further craziness, I do this:



function weekDayOf($year,$month,$dayoftheweek,$occurance) {

    /*

     * returns the # occurance of the day of the week. Such as the 3rd sunday

     * if occurance is null it will return the whole array. for the week days in that month

     * it can be accessed by $date[$dayoftheweek][$occurance]=date;

     */

    $mdays=date("t",mktime(0,0,0,$month,1,$year)); //days in the current month

    $first_day = date('w',mktime(0,0,0,$month,1,$year)); // day of the week the month started with

    $day_oc = array(); // occurances of each day of the week

    for($i=0;$i<$mdays;++$i){

        $dayofweek = ($i+$first_day)%7;

        if(!is_array($day_oc[$dayofweek])) {

            $day_oc[$dayofweek] = array();

        }

        $day_oc[$dayofweek][]=$i+1;

    }

    $n = $occurance;

    while($n > 0 && !isset($day_oc[$dayoftheweek][$n]))

        $n--;

    return $day_oc[$dayoftheweek][$n];

}

Two comments below give us superfluous code.



Firstly, arkin AT REMOVESPAM DOT arkinex DOT com has posted a function that "takes 2007-09-19 21:05:23 and turns it into a unix timestamp."  The built-in PHP function  strtotime()  can do this, so defining another function is unnecessary:



<?php



$timestamp = strtotime("2007-09-19 21:05:23");



?>



And secondly, vikram dot dhanjal at gmail dot com gives us "Code for generating time stamp for current time." Again, strtotime()  can do this, but PHP also has a built-in function for that very purpose: time().



<?php



$timestampRightNow = strtotime("Now");



// or simpler still:



$timestampRightNow = time();



?>



time() is quicker than strtotime("Now") as PHP does not need to parse the string provided.

Code for generating time stamp for current time. May be useful for someone working on date and time things.

/*Full right to modify and use it.*/



list($ch,$ci,$cs,$cm,$cd,$cy)=explode(",",date("H,i,s,m,d,y"));    $now=mktime($ch,$ci,$cs,$cm,$cd,$cy);



echo $now;

A refinement on my last  post is this one. It will output the current date and time of the user... just one simple line of code!



<?    

  $date = date('d-m-Y, H:i',(time()-date('Z')));

?>



Kind regards,

I have to work out the day before an event to send an email notification.  But if the day before was on a weekend I had to make sure the email was send on the Friday before the weekend.  I didn't see anything like this around so here is what i wrote.

Hope it helps some one else.



<?php

$dates     = explode("/", "09/22/2007");

$month     = $dates['0'];

$day       = $dates['1'];

$year      = $dates['2'];

$yesterday = mktime(0,0,0,$month,$day-1,$year);

$notification = date('l',$yesterday);

if(in_array($notification, array("Saturday", "Sunday"))){

    $notification = "Friday";

}

echo("<p>{$notification}</p>");

?>

www.globalprompt.net
20-Sep-2007 11:50


function dateDiff($dformat, $endDate, $beginDate)

    {

    $date_parts1=explode($dformat, $beginDate);

    $date_parts2=explode($dformat, $endDate);

    $start_date=gregoriantojd($date_parts1[0], $date_parts1[1], $date_parts1[2]);

    $end_date=gregoriantojd($date_parts2[0], $date_parts2[1], $date_parts2[2]);

    return $end_date - $start_date;

    }



Now let us see how we use this function:



    $date1="07/11/2003";

    $date2="09/04/2004";



    print "If we minus " . $date1 . " from " . $date2 . " we get " . dateDiff("/", $date2, $date1) . ".";

This snippet takes 2007-09-19 21:05:23 and turns it into a unix timestamp, created and found very useful on a project i just did.



<?php

function make_timestamp($date) {

list($year, $month, $day, $hour, $minute, $second) = split('[-: ]', $date);

return mktime($hour, $minute, $second, $month, $day, $year);

If you want to define your own time without having trouble with the server time you could do this;



<?

  $timeZoneOffset = +1; //timezone where the user is (use an additional script to determine this variable)



  $H = (date('H')+date('O'))+$timeZoneOffset; //hour

  $i = date('i'); //minutes

  $s = date('s'); //seconds

  $m = date('m');  //month

  $d = date('d') //day

  $Y = date('Y') //year

  $date = date('Y-m-d, H:i:s',mktime($H,$i,$s,$m,$d,$Y)); // will output somthing like 2007-09-13, 03:52:05

Well I looked all over the place for this and couldn't find it so I made my own. Hopefully it saves someone else some time. It will give you the occurances of a day in a month. For example if you want to get the date of the 2 Tuesday in a month.



<?php



function weekDayOf($year,$month,$dayoftheweek=null,$occurance=null) {

    /*

     * returns the # occurance of the day of the week. Such as the 3rd sunday

     * if occurance is null it will return the whole array. for the week days in that month

     * it can be accessed by $date[$dayoftheweek][$occurance]=date;

     */

    $mdays=date("t",mktime(0,0,0,$month,1,$year)); //days in the current month

    $first_day = date('w',mktime(0,0,0,$month,1,$year)); // day of the week the month started with

    $day_oc = array(); // occurances of each day of the week

    for($i=0;$i<$mdays;++$i){

Diff between date seconds, minutes, hours, month, days and years!



Very usefull and so simple :-)



$d1=mktime(22,0,0,1,1,2007);

$d2=mktime(0,0,0,1,2,2007);

echo "Hours difference = ".floor(($d2-$d1)/3600) . "<br>";

echo "Minutes difference = ".floor(($d2-$d1)/60) . "<br>";

echo "Seconds difference = " .($d2-$d1). "<br>";



echo "Month difference = ".floor(($d2-$d1)/2628000) . "<br>";

echo "Days difference = ".floor(($d2-$d1)/86400) . "<br>";

echo "Year difference = ".floor(($d2-$d1)/31536000) . "<br>";

If there is an easier way to find the week of the month, let me know. Here is how I figured out how to do it;



date("W") - date("W",strtotime(date("F") . " 1st " . date("Y"))) + 1;

This will show the day (Monday, Tuesday, etc) for any given date.



<?php

$mon = 12;

$day = 31;

$year = 1980;

$stamp = mktime(0,0,0,$mon,$day,$year);



echo date('l',$stamp);

?>

This will calculate the 'SPOT' date for FX trades (two working days hence) 



<?php



// get the day

$d=date("D");



// if today is Thu or Friday add 4 days to today

if ($d=="Thu" || $d=="Fri") {

$spot  = time() + (4 * 24 * 60 * 60);

echo "<p>";

echo date("d/m/Y", $spot);

echo "</p>";

}



// else just add two days to today

else {

$spot  = time() + (2 * 24 * 60 * 60);

echo "<p>";

echo date("d/m/Y", $spot);

echo "</p>";

}

?>

In relation to soreenpk at yahoo dot com's message:



That code doesn't work for two dates with a difference larger than a year, for example:

$digest_date = "2006-04-14";

$date2="2007-04-15";

$date_diff = date("d",strtotime($date2)) - date("d",strtotime($digest_date));//$date_diff = 1

}



if(isago(20,0))

This function is like date, but it "speaks" Hungarian (or an other language)
