Re: question about str_replace()

If you want to replace all words beginning with "good", you can use pcre's word boundary (\b) feature. echo preg_replace("/\bgood(\w)*/","blah",$sentence); This will replace words like: good goody goodman it will not replace words like: mygood ohgoody It will also find boundaries correctly, so if "good" is immediately preceded by non-word characters, it will still match.
