ID: 35125 Updated by: sniper@php.net Reported By: dmceo415 at yahoo dot com Status: Bogus Bug Type: Filesystem function related Operating System: Windows XP PHP Version: 5.0.5 New Comment: Also note that filemtime() result is cached.

For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Due to the volume of reports we can not explain in detail here why your report is not a bug. The support channels will be able to provide an explanation for you. Thank you for your interest in PHP. We only attach to the libc function. If windows misbehaves -> not our problem, report to Microsoft. ------------------------------------------------------------------------ [2005-11-06 15:08:29] dmceo415 at yahoo dot com Description: ------------ I am backing up a file (the path & filename of which are stored in $original; the path & filename of the copy are stored in $bkup). I would also like to copy the file modification time of $original, so, after copying the file itself, I use: touch($bkup, filemtime($original)); However, after I use the above "touch" function, filemtime($original) and filemtime($bkup) are often slightly different. For example, I might have: echo filemtime($original); // gives 1126191599 echo filemtime($bkup); // gives 1126191600 The "touch" function seems to be giving a slightly incorrect file modification time. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=35125&edit=1
