Project is attached on a .zip file. Read it. This is basic php programming guys. Cleaning titles, deleting characters from titles, finding and replacing text, html, etc. in posts and other small tasks like this. Outputing to the screen "Hello World" is taught after this on most php books I believe. :)
External hack or one click installation/uninstallation plugin, let's discuss that. Anyway, project goes deep in detail to make your work super easy. Please download the file now.
