I am using the following code, in which initially i am taking the difference of two folder structure and then the out put needs to be copied to other folder. here is the code below..

$source = '/var/www/html/copy1';
$mirror = '/var/www/html/copy2';
function scan_dir_recursive($dir, $rel = null) {

  $all_paths = array();
  $new_paths = scandir($dir);

  foreach ($new_paths as $path) {

    if ($path == '.' || $path == '..') {
      continue;
    }

    if ($rel === null) {
        $path_with_rel = $path;
    } else {
        $path_with_rel = $rel . DIRECTORY_SEPARATOR . $path;
    }

    $full_path = $dir . DIRECTORY_SEPARATOR . $path;
    $all_paths[] = $path_with_rel;

    if (is_dir($full_path)) {
      $all_paths = array_merge(
        $all_paths, scan_dir_recursive($full_path, $path_with_rel)
      );
    }

  }

  return $all_paths;

}
$diff_paths = array_diff(
    scan_dir_recursive($mirror),
    scan_dir_recursive($source)
);


/*$diff_path = array_diff($mirror,$original);*/
echo "<pre>Difference ";print_r($diff_paths);

foreach($diff_paths as $path)
{
    echo $source1 = "var/www/html/copy2/".$path;
    echo "<br>";
    $des = "var/www/html/copy1/".$path;
    copy_recursive_dirs($source1, $des);
}

function copy_recursive_dirs($dirsource, $dirdest)
{ 
   $dir_handle=opendir($dirsource);

    mkdir($dirdest,0777);

 while(false!==($file=readdir($dir_handle)))
 {/*echo "<pre>";
  print_r($file);*/
     if($file!="." && $file!="..")
     {
         if(is_dir($dirsource.DIRECTORY_SEPARATOR.$file)) 
         {
            //Copy the file at the same level in the destination folder
            copy_recursive_dirs($dirsource.DIRECTORY_SEPARATOR.$file, $dirdest.DIRECTORY_SEPARATOR.$file);

         }
         else{
            //Copy the dir at the same lavel in the destination folder
             copy ($dirsource.DIRECTORY_SEPARATOR.$file, $dirdest.DIRECTORY_SEPARATOR.$file);

         }
     }
  }
 closedir($dir_handle);
 return true;
}

Whenever I execute the script I get the difference output but do not get the other copy on second folder as per code... Pls help me in rectifying...
