I have a folder with 4 files in it and I'd like to pull the last modified time of the most recent one (which may not always be the same one). Is there a good way to do that?
Use a DirectoryIterator to find the files and then simply compare their modified times. This oughta do it:
$iterator = new DirectoryIterator('path/to/dir');
$mtime = -1;
$file;
foreach ($iterator as $fileinfo) {
if ($fileinfo->isFile()) {
if ($fileinfo->getMTime() > $mtime) {
$file = $fileinfo->getFilename();
$mtime = $fileinfo->getMTime();
}
}
}
There is no need to iterate through the directory - filemtime
will work for most servers, (depending on your configuration):
$LastMod = filemtime("/path/to/dir/.");
The last dot is needed to see the directory as a file and to actually get a last modification date of it.
