Código PHP:
<?php

if($handle = opendir($basePath . $source)){ // if the folder exploration is sucsessful, continue
while(false !== ($file = readdir($handle))){ // as long as storing the next file to $file is successful, continue
if($file != '.' && $file != '..'){
$path = $source . '/' . $file;
if(is_file($basePath . $path)){
if(!is_file($basePath . $dest . '/' . $file) || $overwrite)

}
} elseif(is_dir($basePath . $path)){
if(!is_dir($basePath . $dest . '/' . $file))
