1love Search & Replace is a very simple PHP script from 1love.com to search and replace any text or code, case sensitive or insensitively anywhere in the whole site. This script also creates backups of any files before doing any change or replacing. It also has features like -exclude file types/names, prompt for confirmation/cancel and undo. Installation and Configuration is very simple, a single file to upload, then specify and change some folder rights and it is over.
