Doing a search on google for "spelling suggestion algorithm" turned up a few things. You may want to check them. You'll probably have to implement an outside program. The only way from within PHP that I can think of doing it is with soundex() and similar functions. I know MySQL implements something similar within it, so you can search for words whos "soundex" will match the "soundex" of the word the user supplied. ---John W. Holmes...
