copy directory

My first contribution :).... My function to copy all directory's content, use it as you want but the best way would be to include it in the directory helper because it uses directory_map function or to load both directory helper and whatever helper this function would be in

/**
 * Copy a whole Directory
 *
 * Copy a directory recrusively ( all file and directories inside it )
 *
 * @access    public
 * @param    string    path to source dir
 * @param    string    path to destination dir
 * @return    array
 */    
if(!function_exists('directory_copy'))
{
    function directory_copy($srcdir, $dstdir)
    {
        //preparing the paths
        $srcdir=rtrim($srcdir,'/');
        $dstdir=rtrim($dstdir,'/');

        //creating the destenation directory
        if(!is_dir($dstdir))mkdir($dstdir);
        
        //Mapping the directory
        $dir_map=directory_map($srcdir);

        foreach($dir_map as $object_key=>$object_value)
        {
            if(is_numeric($object_key))
                copy($srcdir.'/'.$object_value,$dstdir.'/'.$object_value);//This is a File not a directory
            else
                directory_copy($srcdir.'/'.$object_key,$dstdir.'/'.$object_key);//this is a dirctory
        }
    }
}
