PHP: strftime - Manual

Description

string strftime ( string format [, int timestamp] )

Returns a string formatted according to the given format string using the given timestamp or the current local time if no timestamp is given. Month and weekday names and other language dependent strings respect the current locale set with setlocale().

The following conversion specifiers are recognized in the format string:

%a - abbreviated weekday name according to the current locale
%A - full weekday name according to the current locale
%b - abbreviated month name according to the current locale
%B - full month name according to the current locale
%c - preferred date and time representation for the current locale
%C - century number (the year divided by 100 and truncated to an integer, range 00 to 99)
%d - day of the month as a decimal number (range 01 to 31)
%D - same as %m/%d/%y
%e - day of the month as a decimal number, a single digit is preceded by a space (range ' 1' to '31')
%g - like %G, but without the century.
%G - The 4-digit year corresponding to the ISO week number (see %V). This has the same format and value as %Y, except that if the ISO week number belongs to the previous or next year, that year is used instead.
%h - same as %b
%H - hour as a decimal number using a 24-hour clock (range 00 to 23)
%I - hour as a decimal number using a 12-hour clock (range 01 to 12)
%j - day of the year as a decimal number (range 001 to 366)
%m - month as a decimal number (range 01 to 12)
%M - minute as a decimal number
%n - newline character
%p - either `am' or `pm' according to the given time value, or the corresponding strings for the current locale
%r - time in a.m. and p.m. notation
%R - time in 24 hour notation
%S - second as a decimal number
%t - tab character
%T - current time, equal to %H:%M:%S
%u - weekday as a decimal number [1,7], with 1 representing Monday
Warning
Sun Solaris seems to start with Sunday as 1 although ISO 9889:1999 (the current C standard) clearly specifies that it should be Monday.
%U - week number of the current year as a decimal number, starting with the first Sunday as the first day of the first week
%V - The ISO 8601:1988 week number of the current year as a decimal number, range 01 to 53, where week 1 is the first week that has at least 4 days in the current year, and with Monday as the first day of the week. (Use %G or %g for the year component that corresponds to the week number for the specified timestamp.)
%W - week number of the current year as a decimal number, starting with the first Monday as the first day of the first week
%w - day of the week as a decimal, Sunday being 0
%x - preferred date representation for the current locale without the time
%X - preferred time representation for the current locale without the date
%y - year as a decimal number without a century (range 00 to 99)
%Y - year as a decimal number including the century
%Z or %z - time zone or name or abbreviation
%% - a literal `%' character

Note: Not all conversion specifiers may be supported by your C library, in which case they will not be supported by PHP's strftime(). Additionally, not all platforms support negative timestamps, therefore your date range may be limited to no earlier than the Unix epoch. This means that e.g. %e, %T, %R and %D (there might be more) and dates prior to Jan 1, 1970 will not work on Windows, some Linux distributions, and a few other operating systems. For Windows systems a complete overview of supported conversion specifiers can be found at this MSDN website.

Example 1. strftime() locale examples


<?php

setlocale(LC_TIME, "C");

echo strftime("%A");

setlocale(LC_TIME, "fi_FI");

echo strftime(" in Finnish is %A,");

setlocale(LC_TIME, "fr_FR");

echo strftime(" in French %A and");

setlocale(LC_TIME, "de_DE");

echo strftime(" in German %A.\n");

?>

This example works if you have the respective locales installed in your system.

Note: %G and %V, which are based on ISO 8601:1988 week numbers can give unexpected (albeit correct) results if the numbering system is not thoroughly understood. See %V above and example below.

For freebsd user:



You can find the full list of your locale under /usr/share/locale.

For example da_DK.ISO8859-1 under this directory will set up the locale to danish.

i had to use the czech representation of time on unix machine, running debian and linux version of apache with php 4



for me the best solution was to use this code:



<php

     setlocale(LC_ALL, 'cs_CZ.iso88592');

?>



then you can do everything in czech language with correct iso-8859-2 encoding ;D

Hi there,



i had the problem that I needed all days of an week with some extra infos. given is day, month, year (selectboxes).



so I hacked this together ...



function ...

<?php

function get_weekdates($year, $month, $day){

  setlocale(LC_ALL, "C");

  //echo "Year $year<br>";

  //echo "Month $month<br>";

  //echo "Day $day<br>";



  // make unix time

  $searchdate = mktime(0,0,0,$month,$day,$year);

  //echo "Searchdate: $searchdate<br>";



  // let�s get the day of week                //    on solaris <8 the first day of week is sunday, not monday

  $day_of_week = strftime("%u", $searchdate);  

  //echo "Debug: $day_of_week <br><br>";

  

  $days_to_firstday = ($day_of_week - 1);        //    on solaris <8 this may not work

  //echo "Debug: $days_to_firstday <br>";



  $days_to_lastday = (7 - $day_of_week);        //    on solaris <8 this may not work

  //echo "Debug: $days_to_lastday <br>";



  $date_firstday = strtotime("-".$days_to_firstday." days", $searchdate);

  //echo "Debug: $date_firstday <br>";



  $date_lastday = strtotime("+".$days_to_lastday. " days", $searchdate);

  //echo "Debug: $date_lastday <br>";



  $d_result = "";                    // array to return



  // write an array of all dates of this week 

  for($i=0; $i<=6; $i++) {

    $y = $i + 1;

    $d_date = strtotime("+".$i." days", $date_firstday);

    

    // feel free to add more values to these hashes

    $result[$y]['year'] = strftime("%Y", $d_date);

    $result[$y]['month'] = strftime("%m", $d_date);

    $result[$y]['day'] = strftime("%d", $d_date);

    $result[$y]['dayname'] = strftime("%A", $d_date);

    $result[$y]['shortdayname'] = strftime("%a", $d_date);

    $result[$y]['sqldate'] = strftime("%Y-%m-%d", $d_date);

  }



  return $result;                    // return the array

}

?>



so you can read all this by doing something like that:



<?php

  $week = get_weekdates($year,$month,$day);



  for($i = 1; $i<=7 ; $i++) {



    echo 'Year: ' . $week[$i]['year'] . '<br>';

    echo 'Month: ' . $week[$i]['month'] . '<br>';

    echo 'Day: ' . $week[$i]['day'] . '<br>';

    echo 'Longname: ' . $week[$i]['dayname'] . '<br>';

    echo 'Shortname: ' . $week[$i]['shortdayname'] . '<br>';

    echo 'Sqldate: ' . $week[$i]['sqldate'] . '<br>';

    echo '<br>';



  }

?>



I hope this helpes someone out there ...

... notes and improvements welcome (via email / pgp preferred)



Note: It does not work on Slowlaris <8 because of the %u problem (see the other posting for further details)

%k will give you %H (hour, 24-hour clock) with the leading zero replaced by a space.  I have only tested this on one linux system so far, it may not work on windows or other linux builds.

james at oicgroup dot net
19-Nov-2004 09:27


In looking for a way to trim the leading zero from a 12 hour time format (08:30 PM for instance), we happened upon %l (lowercase L) quite by accident.  It replaces the leading zero with a space similiar to what %e does with dates, so you get 8:30 PM instead of 08:30 PM.

michiel1978 at hotmail dot com
06-Oct-2004 04:31


As said in these comments, Windows strftime() doesn't support %e. However, to achieve a similar effect (not 100%) you can use %#d. The # flag will remove the leading zero, so you do get single digits, but without the space that would be added by %e in other environments.

To get a RFC 850 date (used in HTTP) of the current time:



gmstrftime ("%A %d-%b-%y %T %Z", time ());



This will get for example:

Friday 25-Jun-04 03:30:23 GMT



Please note that times in HTTP-headers _must_ be GMT, so use gmstrftime() instead of strftime().

The %e "bug" in strftime on Windows systems can be fixed this way...



<?



setlocale(LC_TIME, 'da');



$var1 = strftime("%A den ");



function strftime_e_fix(){



    $var = strftime("%d");



    if($var{0} == 0){$var = $var{1};}



    return($var);



}



$var1 .= strftime_e_fix();



$var1 .= strftime(". %B, %Y");



echo $var1;

Ever wanted to find the first and last dates in a given week? i.e. you have a week number and a year, what date has the first and last days in that week respectively? Below is a function that does just that. You feed it with a week/year and it returns an array with first and last day:



function mk_week_to_dates($week, $year){

        //We start some time into prev year

        $searchdate = mktime(0,0,0,12,20,$year-1);

        //Then we advance $week-1 weeks ahead (no need to search through dates we know won't give results)

        $searchdate = strtotime("+".($week-1)." week",$searchdate);



        $found=false;

        while ($found==false){

                if (date("W",$searchdate) == $week)

                        $found = true;

                else

                        $searchdate = strtotime("+1 day",$searchdate);

        }



        $weekdates['firstday'] = $searchdate;



        $weekdates['lastday'] = strtotime("+6 day",$searchdate);

        return $weekdates;

}

This override for strftime was created to cope with the date limits on Win32 (1970-2037). Current mappings and allows you to calculate daylight savings time etc. for 1902-1969, feel free to add more mappings!



<?PHP

function &strftime ($format = "", $timestamp = false)

{

    if ($timestamp >= 0 && $timestamp <= 2147480047)

    { // between 1 Jan 1970 00:00:00 and 19 Jan 2038 03:14:07 GMT

        return strftime ($format, $timestamp);

    }



    $mappings = Array (

        Array ("start" => 1902, "end" => 1951, "map" => 1986), // 1902-1951 = 1986-2035

        Array ("start" => 1952, "end" => 1969, "map" => 1980), // 1952-1969 = 1980-1997

    );

    

    if ($timestamp < 0)

    {

        $year = 1969;

        while ($timestamp < 0)

        {

            $days = ($year % 4 == 0 && ($year % 100 > 0 || $year % 400 == 0)) ? 366 : 365;

            $timestamp += $days * 86400;

            $year--;

        }

    }

    else // if ($timestamp > 2147480047)

    {

        $year = 2038;

        while ($timestamp > 0)

        {

            $days = ($year % 4 == 0 && ($year % 100 > 0 || $year % 400 == 0)) ? 366 : 365;

            $timestamp -= $days * 86400;

            $year++;

        }

    }



    foreach ($mappings as $mapping)

        if ($year >= $mapping["start"] && $year <= $mapping["end"])

        {

            $find = Array ("%y", "%Y", "%D");

            $replace = Array (substr ($year, -2), $year, "%m/%d/" . substr ($year, -2));

Windows users cannot use the %V specifier for strftime as it is not implemented in the OS.

Following is a possible workaround function to get the ISO 8601:1988 weeknumber.

Note that unlike the previous (20-Jan-2002) function, this function will also fix last week of the year to 01 whenever necessary.



<?php



// Get the week number in ISO 8601:1988 format

// This helsp when %V is not working on your Win32 machine

function getWeekNumber($day, $month, $year) {

 $week = strftime("%W", mktime(0, 0, 0, $month, $day, $year));

 $yearBeginWeekDay = strftime("%w", mktime(0, 0, 0, 1, 1, $year));

 $yearEndWeekDay   = strftime("%w", mktime(0, 0, 0, 12, 31, $year)); 

 // make the checks for the year beginning

 if($yearBeginWeekDay > 0 && $yearBeginWeekDay < 5) {

  // First week of the year begins during Monday-Thursday.

  // Currently first week is 0, so all weeks should be incremented by one

  $week++;

 } else if($week == 0) {

  // First week of the year begins during Friday-Sunday.

  // First week should be 53, and other weeks should remain as they are

  $week = 53;

 }

 // make the checks for the year end, these only apply to the weak 53

 if($week == 53 && $yearEndWeekDay > 0 && $yearEndWeekDay < 5) {

  // Currently the last week of the year is week 53.

  // Last week of the year begins during Friday-Sunday

  // Last week should be week 1

  $week = 1;

 }

 // return the correct ISO 8601:1988 week (in two digit format)

 return( substr('0'. $week, -2) );

}



?>

Note that on Linux kernels before 2.4.* the date functions in PHP will happily accept a date before 01-01-1970 as stated at the top of this man page, post kernel 2.4.* the date functions *do not* work with dates before 1970.





If you've existing scripts doing date validation on dates before 1970, check them before you upgrade your kernel!

The description of strtotime says that it can "Parse about any English textual datetime description into a UNIX timestamp". Be careful, however,  when using "plain English". I was puzzled over why strtotime("June 23, 2003 at 12:00PM") returned a timestamp corresponding to 9:00 AM Central Time, until I realized the "at" was being interpreted as Azores Time or GMT+002. Writing strtotime("June 23, 2003 12:00PM") returned the correct timestamp.

Note to the comment from 'darianlassan at yahoo dot de':



Given a 'bare number' in seconds, e.g. 143567, strftime() will format this number ACCORDING TO YOUR LOCAL TIMEZONE. Thus, for Germany (where you probably are, since you have a .de address) you will get an extra hour, since CET is GMT +1.



If you are interested in simply formatting a number to give you hours, minutes and seconds (very quick for showing time values), then you should ALWAYS use 'gmstrftime' instead, which will not adjust the time for your local timezone.



Example: I have the decimal value 1.76 minutes returned to me by an application, and want to show this as MM:SS:



  # time value comes as minute value in decimal

  $time = 1.76;



  # convert to seconds

  $min = floor($time);

  $sec = round((($time - $min) * 60));

  $time_value = ($min * 60) + $sec;



  # format using gmstrftime()

  $fmt_time = gmstrftime("%M:%S",$time_value);



  # display

  echo "Time in minutes:seconds = $fmt_time";



cheers,



Nalfy.

I recently needed a way to find the first second of the current week. The catch was that strftime("%u") considers Monday as the first day of the week, whereas I needed things based on Sundays.



My solution was to determine how many days had elapsed since the previous Sunday (0 if today is a Sunday), and subtract that may days from the current day's midnight timestamp:



$weekstart = mktime(0, 0, 0, date("m"), date("d"), date("Y")) - ((strftime("%u") == 7) ? 0 : (86400 * strftime("%u")));



This will assign the epoch stamp of the most recent Sunday at 00:00 (today at 00:00, if today is a Sunday) to $weekstart.

I am truly sorry - I contributed with a script to overcome the missing %V for Windows-users. It contained a serious flaw, that prohibited in some cases. Below is a script, that should work in all cases. I have tested it on most outer cases, e.g. 2005/12/31 and 2006/01/01.





function ISOWeek($y, $m, $d)


{


$week=strftime("%W", mktime(0, 0, 0, $m, $d, $y));


$dow0101=getdate(mktime(0, 0, 0, 1, 1, $y));


$next0101=getdate(mktime(0, 0, 0, 1, 1, $y+1));





 if ($dow0101["wday"]>1 && 


    $dow0101["wday"]<5)


   $week++;


 if ($next0101["wday"]>1 && 


    $next0101["wday"]<5 &&


     $week==53)


   $week=1;


 if ($week==0)


   $week = ISOWeek($y-1,12,31);





 return(substr("00" . $week, -2));

setlocale(LC_ALL, "de_DE");

strftime("%d. %B %Y");



It could be that it doesn't work. Try "ge" instead of "de_DE".



setlocale(LC_ALL, "ge");

strftime("%d. %B %Y");



That will return "04. Dezember 2002"

The provided example is very bad for newbies. Why does setlocale with "C" print out a date in english? Why is this not even documented on the setlocale page? Why is the example text inserted into the strftime function? Such hacks are a sure way to confuse a lot of people.



Examples should be as simple as possible. Remember that people are here because they don't know everything but would like to know.



So if you are a newbie like me, here is the same example, formatted differently, so that you may understand it more easily:



echo "The current time with your standard settings is: ";

setlocale (LC_TIME, "C");

// C stands for "standard settings"

echo strftime ("%A");



echo " in finnish: ";

setlocale (LC_TIME, "fi_FI");

echo strftime ("%A");



echo " in french: ";

setlocale (LC_TIME, "fr_FR");

echo strftime ("%A");



echo " in german: ";

setlocale (LC_TIME, "de_DE");

echo strftime ("%A");

If you are using MySQL database timestamps and you wish

to display for example the time and date represented by such

a timestamp, you can use the following function:



function DateAndTime ($timestamp)

{

        list($year,$month,$day,$hour,$minute,$second) =

             sscanf($timestamp,"%4s%2s%2s%2s%2s%2s");



        setlocale("LC_TIME","nl_BE.ISO8859-15@euro");



        return strftime("%c",

             mktime($hour,$minute,$second,

             $month,$day,$year));

}



This function will return the correct date and time in the

locale of your choice, in the default representation.



example:

----------



list($timestamp,$dummy1, ..) = mysql_fetch_row($result);

$displaytime = DateAndTime($timestamp);

echo "The date and time is: $displaytime";



I hope you find this usefull ..

If you are building a web app that will be used by people different timezones from the server on which the app is running, you can switch the timezone on the fly by doing the following before calling strftime (), or the other timestamp processing functions.





This is very easy if you know how to do it.  If you don't you'll spend hours trying to manually slide timestamps around.





putenv ("TZ=PST8PDT");


print strftime ("%T %Z");


putenv ("TZ=EST5EDT");


print strftime ("%T %Z");





Valid timezone codes can (usually) be seen (on Linux, at least) in /usr/share/zoneinfo or /usr/lib/zoneinfo (according to the tzset manpage).

Actaully, %p returns 'AM' or 'PM', not 'am' or 'pm'.

Here's a pair of functions to convert a date to an ISO 8601 year/week and vice versa.



function yearweek($date="") {

   if (!$date) $date = mktime();

   $yearweek =  strftime("%G%V", $date);

   return $yearweek;

}



function dateEndYearweek($yearweek) {

   $weekEndDay = 0;   // 0 = Sunday.

   $year = (int) substr($yearweek, 0, 4);

   $week = (int) substr($yearweek, -2, 2);

   // We know that the 4th Jan is always in week 01, 11th Jan in week 02, ...

   // so day (4 + (w-1)*7) is in week w.

   $dayOfYear = 4 + (($week - 1) * 7);

   $date = mktime(0, 0, 0, 1, $dayOfYear, $year);

   // Find the last day of this week.

   $dayOfWeek = date("w", $date);

   $daysToAdd = ($weekEndDay - $dayOfWeek + 7) % 7;

   $date += $daysToAdd * 24*60*60;

   return $date;

}

To write the data of a mySQL data base 

I suppose: setlocale (LC_TIME, "hu_HU");

$filemod = filemtime("/var/lib/mysql/somewhere/table_name.ISM");

$filemodtime = date("Y F j H:i:s T", $filemod);

echo strftime('%Y %B %d %A %H �ra %M perc', $filemod);

Under Windows the %W works wrong: it gives 1 for 2001.01.01 instead of 0! Be careful with strftime under Windows.

Using a class to format a date.

 

This example shows how to format a date using a timestamp.  You can obtain the timestamp through your MySQL Select statement, e.g, SELECT UNIX_TIMESTAMP(date_field) as my_timestamp FROM table, or by using strtotime, e.g., $my_timestamp = strtotime (date_field).



// This class expects a date array value and returns a formatted date.  You can add additional methods to return different date formats--obviously!



<?php

class DateMake {



  var $month;

  var $day;

  var $year;

    

  function DateMake($ts="") {

            

      $date_time_array = $ts;

            

      $this->month = $date_time_array["mon"];

      $this->day =  $date_time_array["mday"];

      $this->year =  $date_time_array["year"];

            

    return ($this->month."/".$this->day."/".$this->year);

 

}

    

    function Month() {

         return $this->month;

    }

    function Day() {

         return $this->day;

    }

    function Year() {

         return $this->year;

    }

}

?>



// Add the "require_once" reference

to each php page which needs to use this class.



require_once("class.DateMake.php");



// instantiate the class 



$oDateMake = new DateMake();



// call the method.  The timestamp is passed to getdate(), (you can also pass an empty getdate() to the class to return the current date).



$myDate = $oDateMake->DateMake(getdate($myresult['my_timestamp']));



You can modify this class or create your own date formatting class; whichever you choose, the important thing to note about classes is that they can replace in-line data formatting code in your php pages with re-usable polymorphic code.

Using strftime() with a negative Unix Timestamp doesn't seem to work.

I'm trying to format a birthdate before 1 January 1970.



...

$time= mktime(0,0,0,$birthmonth,$birthday,$birthyear); 

return strftime("%e ",$time) . ucfirst(strftime("%B ",$time)) . strftime("%Y ",$time);

}



the returned string is a blank string everytime my $time is a negative timestamp.

To get Swedish this works on win32 (w2k)



<?php

setlocale (LC_ALL, "");

print (strftime ("%A den %e %B %Y"));

?>



%e does, however, not work.

I saw issues with locale settings...



this one works on php-apache-windows and cobalt-apache servers :



setlocale ("LC_TIME","french");



rather than "fr"...

It seems that the %W doesn't work for 2002, it says that this week is week 1 and that's not correct.

I have no code to correct this yet but I guess that it will have to suffise to ++ it for now!

All system doesn't have all LC_* information, my Slackware 8 didn't have LC_TIME for example.





I made them (swedish example) using 'localedef -f ISO-8859-1 -i sv_SE sv' in /usr/share/locale.

Some of the modifiers differ on win32


 (eg. %u -> %w, %e -> %d).


Search at http://msdn.microsoft.com/ for strftime().

Note that setting LC_TIME is not enough for some locales under Windows, e.g. Czech, because there are some characters not contained in default (US) character set like '�' (c with hook), '�' (r with hook).








If you run Apache as regular application and have set your locale to Czech (ControlPanel/RegionalOptions), there is no problem and 'September' is correctly translated as 'z���', 'Thursday' as '�tvrtek'.


But if you run Apache as service, you get 'z�r�', and 'ctvrtek'.


To get things work as you expect you must set LC_CTYPE beside LC_TIME, or set LC_ALL.





<?


  $locale = 'Czech_Czech.1250';


  $res = setlocale( 'LC_CTYPE', $locale); //important


  $res = setlocale( 'LC_TIME', $locale);


  echo strftime( '%A %m. %B %Y', mktime( 0,0,0,9,6,2001));


?>

Beware of '%D':


the comment shown expects that this is the same as '%m/%d/%y'.





This is wrong: '%D' is only expected to returned an abbreviated numeric date according to the current locale:


In the German locale '%D' is '%y.%m.%d'


In the French locale '%D' is '%d/%m/%y'





The locale rules still apply to %D as with '%A'...





Beware that some C libraries do not support '%D' and/or '%A'  or do not support them accordingly. Using strftime() is then system-dependant, because PHP use the C function provided by the system on which it runs.

Solaris 2.6 and 7 define the


%u specifier differently than noted here. Day 1 is Sunday, not Monday. Solaris 8 gets it right.

there's a tricky way to print all weekdays in local language e.g.:





<?


setlocale("LC_TIME", "pl_PL");


for($i=0;$i<=6;$i++) { print(strftime("%A",mktime(0,0,0,2,$i,0))."\n"); }


?>





enjoy it :)

Be careful by using strftime() to display a period in seconds userfriendly. strftime("%H",3600) will return "02" but the period is one hour. So subtract 3600 to get it right.

Locale names are OS dependent. HP-UX 11.0, for example, has three


German locales, de_DE.roman8, de_DE.iso88591, and 


de_DE.iso885915@euro.


The command locale -a will display all available locales on a system.





So on HP-UX, to get German dates: 


setlocale("LC_TIME", "de_DE.roman8");


print(strftime("%A\n"));
