Bug description:getlastmod() should (optionally) check modification times of
include files also
Description:
------------
Currently the getlastmod() function is essentially an alias for
filemtime($_SERVER["SCRIPT_FILENAME"]).
Considering that a primary use case for this function is to supply the time
for a HTTP Last-Modified header, and that the output of the page may change
if any of its include or require files change, it would be nice to have the
option for getlastmod() to return the latest modification time of (any of)
the main script AND its includes (recursively, checking includes of
includes and so on). (At least the ones included up to the time the
function was called, if they can't be checked in advance during some
parsing phase?)
To preserve backward compatibility, this feature might be activated by
passing the parameter "true", i.e. getlastmod(true) to check include files
also.
A php-coded version of what I mean is included below just for
clarification, although it can't (I think) check multiply-nested include
files.
Test script:
---------------
function new_getlastmod($checkAll = false)
{
if (!$checkAll) return getlastmod();
$t = 0;
foreach(get_included_files() as $f)
if ((($mt = filemtime($f))!==false)&&($mt>$t)) $t = $mt;
return ($t ? $t : false);
}
