strftime

(PHP 4, PHP 5)

strftime — Format a local time/date according to locale settings

Description

string strftime ( string $format [, int $timestamp = time() ] )

Format the time and/or date according to locale settings. Month and weekday names and other language-dependent strings respect the current locale set with setlocale().

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, so your date range may be limited to no earlier than the Unix epoch. This means that %e, %T, %R and, %D (and possibly others) - as well as 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 » MSDN.

Warning

Contrary to ISO-9899:1999, Sun Solaris starts with Sunday as 1. As a result, %u may not function as described in this manual.

timestamp

The optional timestamp parameter is an integer Unix timestamp that defaults to the current local time if a timestamp is not given. In other words, it defaults to the value of time().

Return Values

Returns a string formatted according format 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().

Errors/Exceptions

Every call to a date/time function will generate a E_NOTICE if the time zone is not valid, and/or a E_STRICT or E_WARNING message if using the system settings or the TZ environment variable. See also date_default_timezone_set()

As the output is dependent upon the underlying C library, some conversion specifiers are not supported. On Windows, supplying unknown conversion specifiers will result in 5 E_WARNING messages and return FALSE. On other operating systems you may not get any E_WARNING messages and the output may contain the conversion specifiers unconverted.

Changelog

Version	Description
5.1.0	Now issues the `E_STRICT` and `E_NOTICE` time zone errors.

Examples

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

Notes

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 examples in this manual page.


The format "%e" does not work on Windows.

There is a bug entry : http://bugs.php.net/bug.php?id=45847



It's because strftime is not portable, it use the operating system function.

For Win32, to get more documentation we have to consult the Windows "Run-Time Library Reference" for strftime :

http://msdn.microsoft.com/en-us/library/fe06s4ak%28VS.71%29.aspx



And we can find the solution:

  replace "%e" by "%#d"

the "#" remove leading zeros (if any).

Created this small method to convert a date format to a strftime format. One format is enough to learn :)





<?php


/**


 * Convert a date format to a strftime format


 * 


 * Timezone conversion is done for unix. Windows users must exchange %z and %Z.


 * 


 * Unsupported date formats : S, n, t, L, B, G, u, e, I, P, Z, c, r


 * Unsupported strftime formats : %U, %W, %C, %g, %r, %R, %T, %X, %c, %D, %F, %x 


 * 


 * @param string $dateFormat a date format


 * @return string


 */


public static function dateFormatToStrftime($dateFormat) {


    


    $caracs = array(


        // Day - no strf eq : S


        'd' => '%d', 'D' => '%a', 'j' => '%e', 'l' => '%A', 'N' => '%u', 'w' => '%w', 'z' => '%j', 


        // Week - no date eq : %U, %W


        'W' => '%V',  


        // Month - no strf eq : n, t


        'F' => '%B', 'm' => '%m', 'M' => '%b', 


        // Year - no strf eq : L; no date eq : %C, %g


        'o' => '%G', 'Y' => '%Y', 'y' => '%y', 


        // Time - no strf eq : B, G, u; no date eq : %r, %R, %T, %X


        'a' => '%P', 'A' => '%p', 'g' => '%l', 'h' => '%I', 'H' => '%H', 'i' => '%M', 's' => '%S',


        // Timezone - no strf eq : e, I, P, Z


        'O' => '%z', 'T' => '%Z',


        // Full Date / Time - no strf eq : c, r; no date eq : %c, %D, %F, %x  


        'U' => '%s' 


    );


    


    return strtr((string)$dateFormat, $caracs);


}


?>





I use it with this condition on a date format : 


if(preg_match("/(D|l|F|M)/", $format))

You can remove leading "0" from %m (two digit representation of the month) by using "-".

%-m  => Month of the year (1 to 12) without leading zero

On the Linux server I'm using, strftime() also accepts a "-" option to request no padding:



<?php

$ts = strtotime("4 Nov 2009");

echo strlen(strftime("%-e", $ts)), "\n"; // "1" (no padding)

echo strlen(strftime("%e", $ts)), "\n"; // "2" (space padded)

This is that worked with UTF-8 encoding on Linux server, with right accents:

<?php

setlocale(LC_ALL, 'hu_HU.UTF8');

echo(strftime('%Y. %B %d. %A'));

?>



Output is:

2009. november 02. hétfő



Also, this one can be used, if not utf-8 preferred:

<?php

setlocale(LC_ALL, 'hu_HU.ISO8859-2');

?>



UTF-8 is not supported on windows platforms, so there the iconv workaround must be used:

<?php

setlocale(LC_ALL, 'hun_hun');

echo(iconv('ISO-8859-2', 'UTF-8',strftime('%Y. %B %d. %A')));

?>



The output is the same as before. Note that, the iconv first parameter is ISO-8859-2 not ISO-8859-1, because the locale is hungarian which uses 8859-2 codepage as default. It is needed for the right accents.



If you want use the same code for Windows and Linux platforms, the second one is the right option (the iconv trick), but the locale configuration must be different (Linux: hu_HU, windows: hun_hun), but in that case the UTF8 tag is not needed for the Linux config.

This is so simple it has to be found in one of all the comments on all those different time functions. But since I didn't find it, here it is: Use this to convert between different time formats:



<?PHP

if (!function_exists('convertTime')) {

  /** Converts time strings from one format into another using

   *  PHP formats.

   *

   *  @param String $dformat Format to convert to

   *  @param String $sformat Format to convert from, e.g. format

   *      of $ts

   *  @param String $ts Time string to be converted

   *  @return String Supplied time translated to the format specified

   *    in $dformat

   */

  function convertTime($dformat,$sformat,$ts) {

    extract(strptime($ts,$sformat));

    return strftime($dformat,mktime(

                                  intval($tm_hour),

                                  intval($tm_min),

                                  intval($tm_sec),

                                  intval($tm_mon)+1,

                                  intval($tm_mday),

                                  intval($tm_year)+1900

                                ));

  }

}



/*

 * And for the test....

 */

echo convertTime('%Y-%m-%d','%d.%m.%Y','27.11.2009');

?>



This should print "2009-27-11".



I did not put much effort in this code. The task also seems "too simple to be neccessary". But as I said, I didn't find anything to help me with this.



Cheers,

I had a need to subtrackt an older time from current time to get the time between. 

Example: If one has worked from 2009-03-16 11:33:54 to 2009-03-16 12:01:54 then he has worked X hours,minutes and seconds. I tried to find that X. And so - one solution would be:

<?php

$start_date = strtotime("2009-03-16 11:33:54"); //start date from database - date("Y-m-d H:i:s") made as UNIX timestamp

$end_date = strtotime("2009-03-16 12:01:54"); //end date from database - date("Y-m-d H:i:s") made as UNIX timestamp

$ajavahe = $end_date - $start_date;

$time_between = gmstrftime('%Hh %Mm %Ss', $ajavahe); //gmstrftime() deals with different timezones correctly. (If in example you would be situated in Estonia and you would use strftime() you get wrong answer off by 2 hrs, because timezone is GMT+2 - with gmstrftime() comes right answer.)



echo 'You have worked: '.$time_between;

?>

Hope that this one makes someones life easier :D

For windows user:



If you unsuccessfully change date/time format to your locale country using xx_XX format, try using XXX format or ISO-639 country codes format.



See complete list for ISO-639 here: http://www.w3.org/WAI/ER/IG/ert/iso639.htm



For example:



<?php

setlocale(LC_ALL, 'IND');

echo strftime("Today in Indonesia is %A");

Here's a simple version for date formating i use between displaying in HTML and converting back to MYSQL format:





<?php


function format_date($original='', $format="%m/%d/%Y") {


    $format = ($format=='date' ? "%m-%d-%Y" : $format);


    $format = ($format=='datetime' ? "%m-%d-%Y %H:%M:%S" : $format);


    $format = ($format=='mysql-date' ? "%Y-%m-%d" : $format);


    $format = ($format=='mysql-datetime' ? "%Y-%m-%d %H:%M:%S" : $format);


    return (!empty($original) ? strftime($format, strtotime($original)) : "" );


}


?>





example (in HTML or webapp):


[grab from database]...


$dbase_stored_date = "2007-03-15";


$display_html_date = format_date($dbase_stored_date);


... displays as "03/15/2007"





example (saving form via on POST/GET):


$update_date = format_date($_POST['display_html_date'], 'mysql-date');


// converts back to '2007-03-15'


.... [your mysql update here]





Don't forget to sanitize your POST/GET's   =)

note, that for some languages you MUST set LC_ALL instead of LC_TIME.



note that you further have to explicitly define your output-encoding (default is ISO-8859-1 [which makes problems for some languages])!



at least i expirienced this behaviour on a german WinXP-PHP4 environment:



<?php



// does not work - gives question marks:

setlocale(LC_TIME, 'RUS'); // ISO Alpha-3 is supported by xp

echo strftime('%A', time());



?>



<?php



// DOES work:

header('Content-Type: text/html; charset=UTF-8'); // you could also use another charset here if iconv isn't installed on your system.

This little function allows you to provide a reasonably human readable string and convert to a timestamp - see example in comments below.



I find it far more useful than having to remember all the '%' modifiers. Am also well aware of its failings but it works in a lot of the real life situations I've come across.



<?php

function AmazingStringFromTime($str, $nTimestamp = null)

{

    // This function reads a human readable string representation of dates. e.g.

    // DD MM YYYY => 01 07 1978

    // DDD D MMM YY => Mon 1 Jul 78

    

    $arrPairs = array(

    "DDDD"  => "%A",

    "DDD"   => "%a",

    "DD"    => "%d",

    "D"     => "%e", // has leading space: ' 1', ' 2', etc for single digit days

    "MMMM"  => "%B",

    "MMM"   => "%b",

    "MM"    => "%m",

    "YYYY"  => "%Y",

    "YY"    => "%y",

    "HH"    => "%H",

    "hh"    => "%I",

    "mm"    => "%M",

    "ss"    => "%S",

    );

    

    $str = str_replace(array_keys($arrPairs), array_values($arrPairs), $str);

    return strftime($str, $nTimestamp);

}

?>

Function strftime() use the locales installed in your system (linux). 



If you are like me and only leave in the system the locales you use normally (en_US and your own language locale, like es_ES), you'll only be able to use the locales installed. If your application is translated to other languages, you need these locales too.



The name of the locale in your system is important too. This can be a problem when you want to distribute the app.



If you have this locales in your system:

en_US/ISO-8859-1

en_US.UTF-8/UTF-8

es_ES/ISO-8859-1

es_ES@euro/ISO-8859-15

es_ES.UTF-8/UTF-8

es_ES@euro/UTF-8



and use setlocale('es_ES'), the result will use the iso-8859-1 charset even if you have all your system, files and configuration options in UTF-8. To receive content in UTF-8, in this example, you need to use setlocale('es_ES.UTF-8') or setlocale('es_ES.UTF-8@UTF-8').



The definition of locales can change from one system to another, and so the charset from the results.

(in addition to Andy's post)


To get a RFC 2822 date (used in RSS) of the current local time :





echo strftime ("%a, %d %b %Y %H:%M:%S %z") ;





Note: option %z / %Z - work different on Windows platform, for example


output of this code line can be:


Thu, 02 Nov 2006 09:54:59 Jerusalem Standard Time (on Windows)


Thu, 02 Nov 2006 09:54:59 +0200                   (on Linux)





[red. It is much smarter to use date(DATE_RSS); here]

Under windows if you are using Japanese version, you must use the following code:



setlocale(LC_ALL, "Japanese_Japan.20932") for EUC

setlocale(LC_ALL, "Japanese_Japan.932") for SJIS



I found the following page that helped me with this issue:

The following function implements the conversion specifiers which are not supported on Win32 platforms:



(Note: the specifiers %V, %G and %g can be implemented using other functions described in this section)



<?php



function strftime_win32($format, $ts = null) {

    if (!$ts) $ts = time();



    $mapping = array(

        '%C' => sprintf("%02d", date("Y", $ts) / 100),

        '%D' => '%m/%d/%y',

        '%e' => sprintf("%' 2d", date("j", $ts)),

        '%h' => '%b',

        '%n' => "\n",

        '%r' => date("h:i:s", $ts) . " %p",

        '%R' => date("H:i", $ts),

        '%t' => "\t",

        '%T' => '%H:%M:%S',

        '%u' => ($w = date("w", $ts)) ? $w : 7

    );

    $format = str_replace(

        array_keys($mapping),

        array_values($mapping),

        $format

    );



    return strftime($format, $ts);

}

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().

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.





<?php


  $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));

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: 





<?php


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


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


?>
