PHP header "Last-Modified"

[Mcod]

Hi there,

 

I am currently running into an issue with my Last-Modified header.

I have a news artcle script which stores the publication date as Y-m-d, so I tried to send the following header via PHP:

 

header("Last-Modified: ".$articledate." 1:00:00 GMT");

 

However, when I test the headers with a header tool, it always shows:

 

Thu, 01 Jan 1970 00:00:00 GMT

 

instead of what I want it to show. I wonder what I would have to do to show the Last-Modified header correctly, as this is important to me as I need to index all my pages using the correct data. Please note that I cannot use the file date, as the pages are dynamic, so there is no real file to get the date from.

 

Your help would be greatly appreciated.

when you echo out $articledate what does it display?

And the actual format for that date is thus -

Last-Modified: Tue, 15 Nov 1994 12:45:26 GMT

I managed to fix this - might be a bit "dirty" but it works for me:

 

$articledate = "2012-01-25";
$utc = $articledate;
$utc = strtotime($utc);
header('Last-Modified: '.gmdate('D, d M Y H:i:s \G\M\T', $utc));
