Req #64885 [Opn->Sus]: getlastmod() should (optionally) check modification times of include files also

Edit report at https://bugs.php.net/bug.php?id=64885&edit=1 ID: 64885 Updated by: cmb@php.net Reported by: dean at omnivisiontechnology dot com Summary: getlastmod() should (optionally) check modification times of include files also -Status: Open +Status: Suspended Type: Feature/Change Request Package: Filesystem function related PHP Version: 5.5.0RC1 Block user comment: N Private report: N New Comment: The given test script shows that this functionality can easily be implemented in userland, so adding it as built-in feature appears to be doubtful. If you still like to see it, please pursue the RFC process[1].

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); } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=64885&edit=1
