Header expire doesn't work

I tested this script that I found on this web site:

function setExpires($expires) {
header(
'Expires: '.gmdate('D, d M Y H:i:s', time()+$expires).'GMT');
}
setExpires(10);
echo ( 'This page will self destruct in 10 seconds<br />' );
echo ( 'The GMT is now '.gmdate('H:i:s').'<br />' );
echo ( '<a href="'.$_SERVER['PHP_SELF'].'">View Again</a><br />' );

When I refresh the page, the time updates every sec instead of every 10 sec.

"If we follow this link, we’ll notice the time updates only once every ten seconds"

Okay, I'm hoping you didn't make this typo, but I'll point it out to you anyway:

header('Expires: '.gmdate('D, d M Y H:i:s', time()+$expires).'GMT');

Should have a space behind the seconds field:

header('Expires: '.gmdate('D, d M Y H:i:s ', time()+$expires).'GMT');
//                                       ^-- add space here
