gmstrftime

(PHP 4, PHP 5, PHP 7, PHP 8)

gmstrftime — Formatta una data/ora GMT/UTC secondo i parametri locali

Descrizione

gmstrftime(string $formato, int $timestamp = ?): string

Si comporta allo stesso modo della funzione strftime() eccetto che l'orario restituito è del Greenwich Mean Time (GMT). Ad esempio, quando si è nell' Eastern Standard Time (GMT -0500), la prima linea sotto scrive "Dec 31 1998 20:00:00", mentre la seconda scrive "Jan 01 1999 01:00:00".

Example #1 Esempio di gmstrftime()

setlocale ('LC_TIME', 'en_US');
echo strftime ("%b %d %Y %H:%M:%S", mktime (20,0,0,12,31,98))."\n";
echo gmstrftime ("%b %d %Y %H:%M:%S", mktime (20,0,0,12,31,98))."\n";

HTTP 1.1 (RFC 2068) requires an RFC 1123 date with a four digit year, so the correct format to use for a Last-modified header would look something like this:

<?php
header("Last-modified: " . 
gmstrftime("%a, %d %b %Y %T %Z",getlastmod()));
?>

If you want the dutch time on your pages and you are hosted on a server in the USA you can easily change it this way:



<?php

setlocale(LC_TIME, 'nl_NL');

$tgl = gmstrftime("%d %B %Y - %H:%M uur",time()+3600);

?>



Then use $tgl to display the right time.

Note the +3600 is a day light savings time correction.

The result: 22 maart 2005 - 16:39 uur



First I used the normal date function and this was the previous result: March 22, 2005 - 04:28 AM



I needed it for a dutch guestbook.



I'm new to PHP and it took me a while to find it out and maybe it's of no use for experienced PHP programmers but I thought people can always ignore my post :)

gmstrftime() should not be used to generate a RFC 850 date for use in HTTP headers, since its output is affected by setlocale().

Use gmdate instead:

gmdate('D, d M Y H:i:s') . ' GMT';

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().
