[RESOLVED] Date of the latest file in Folder

[zzz]

If I have a folder with files (PDF) how can I get the date of the latest file uploaded?

To do this, you'll want to use [man]filemtime/man. One user-contributed note (link) seems to do exactly what you want:

function mostRecentModifiedFileTime($dirName,$doRecursive) {
    $d = dir($dirName);
    $lastModified = 0;
    while($entry = $d->read()) {
        if ($entry != "." && $entry != "..") {
            if (!is_dir($dirName."/".$entry)) {
                $currentModified = filemtime($dirName."/".$entry);
            } else if ($doRecursive && is_dir($dirName."/".$entry)) {
                $currentModified = mostRecentModifiedFileTime($dirName."/".$entry,true);
            }
            if ($currentModified > $lastModified){
                $lastModified = $currentModified;
            }
        }
    }
    $d->close();
    return $lastModified;
}

Yep, perfect! I must've been looking elsewhere in the manual...

Hey all. I have also the following code with functions which send the file to the data base with Insert createCallAttachment is a function to send data to database. The functions are fine and I just have here the code which compares the files in a folder according to the date and time they are entered(filemtime). for some reason in the loop the files are sent to the data base more than once and do u have any clue? oh my God is my question clear with my bad english?

function compare($a,$b){
return $b[1]-$a[1];
}
function read_dir($path) {
$files = Array();
if ($handle = opendir($path)) {
while (false !== ($fileSName = readdir($handle))) {
if ($fileSName != "." && $fileSName != "..") {
$files[] = Array($fileSName,filemtime($path.$fileSName));
}
}
closedir($handle);
}
return $files;
}

$files = read_dir($path);
usort($files,"compare");
for($i=0;$i<$num_of_uploads;$i++){
$filename = $files[$i][0];
echo "$filename";
if( !callAttachmentExists( &$connection, $call_id,$filename )) {
createCallAttachment( &$connection, $call_id, $filename );
}}
