CodeCanyon - SiteCloner PHP Script | 
Make Clones of any website
InformationSiteCloner 1.03 is a PHP script that allows you to create copies, clones, or archives of any website. It makes no difference whether this website was created with plain HTML files or with a CMS such as Wordpress or Joomla; SiteClones clones them all!
After creating a clone or copy, you can browse it online, download it as a ZIP archive, send it by email, or upload it to a remote server via FTP.
SiteCloner not only copies the site exactly, but it also rewrites all URLs to be fully relative, allowing you to use the cloned site on a web server or locally on your computer.
