move all files and folders in a folder to another?

Question

I want to move all files and folders inside a folder to another folder. I found a code to copy all files inside a folder to another folder. move all files in a folder to another

// Get array of all source files
$files = scandir("source");
// Identify directories
$source = "source/";
$destination = "destination/";
// Cycle through all source files
foreach ($files as $file) {
  if (in_array($file, array(".",".."))) continue;
  // If we copied this successfully, mark it for deletion
  if (copy($source.$file, $destination.$file)) {
    $delete[] = $source.$file;
  }
}
// Delete all successfully-copied files
foreach ($delete as $file) {
  unlink($file);
}

How do I change this to move all folders and files inside this folder to another folder.

Answer 1

Use rename instead of copy.

Unlike the C function with the same name, rename can move a file from one file system to another (since PHP 4.3.3 on Unix and since PHP 5.3.1 on Windows).

Answer 2

I think the answers are not complete for me, beacuse DIRECTORY_SEPARATOR are not defined on any answer (thans to Edgar Aivars for remember that!), but I want to write my solution for move (rename), copy and delete directory structures (based on this post info, the credits are for yours!).

defined('DS') ? NULL : define('DS',DIRECTORY_SEPARATOR);

function full_move($src, $dst){
    full_copy($src, $dst);
    full_remove($src);
}

function full_copy($src, $dst) {
    if (is_dir($src)) {
        @mkdir( $dst, 0777 ,TRUE);
        $files = scandir($src);
        foreach($files as $file){
            if ($file != "." && $file != ".."){
                full_copy("$src".DS."$file", "$dst".DS."$file");
            }
        }
    } else if (file_exists($src)){
        copy($src, $dst);
    }
}

function full_remove($dir) {
    if (is_dir($dir)) {
        $files = scandir($dir);
        foreach ($files as $file){
            if ($file != "." && $file != ".."){
                full_remove("$dir".DS."$file");
            }
        }
        rmdir($dir);
    }else if (file_exists($dir)){
        unlink($dir);
    }
}

I hope this hepls anyone! (lile me in the future :D )
