In the context of Alex Reply

What if I edit any .jpg file in one folder and save it with the same name as him, this file is already present in another folder. And I want this edited pic to be moved to another folder.? I also have a structured Joomla file structured for comparison

UPDATE 2

I have a recursive function that displays me the full folder structure ... if you can just use it to solve concat ur in ...

<?
function getDirectory($path = '.', $ignore = '') {
    $dirTree = array ();
    $dirTreeTemp = array ();
    $ignore[] = '.';
    $ignore[] = '..';

    $dh = @opendir($path);

    while (false !== ($file = readdir($dh))) {

        if (!in_array($file, $ignore)) {
            if (!is_dir("$path/$file")) {
                $stat = stat("$path/$file");
                $statdir = stat("$path");
                $dirTree["$path"][] = $file. " === ". date('Y-m-d H:i:s', $stat['mtime']) . " Directory == ".$path."===". date('Y-m-d H:i:s', $statdir['mtime']) ;

            } else {

                $dirTreeTemp = getDirectory("$path/$file", $ignore);
                if (is_array($dirTreeTemp))$dirTree = array_merge($dirTree, $dirTreeTemp);
            }
        }
    }
    closedir($dh);

    return $dirTree;
}


$ignore = array('.htaccess', 'error_log', 'cgi-bin', 'php.ini', '.ftpquota');

$dirTree = getDirectory('.', $ignore);
?>
<pre>
    <?
    print_r($dirTree);
    ?>
</pre>
