php - modify (simplify) topic title for displaying in url -

i creating little message board in php , need "simplify" topic title display in url of topic.

examples:

ceci est united nations sujet d'exemple becomes ceci-est-un-sujet-d-exemple

j'ai été à la plage becomes j-ai-ete-a-la-plage

i dislike sp&cial character$ becomes i-dislike-spcial-character (if there improve translation, take it)

edit 1 : strings must utf-8 encoded

edit 2 : learned result of type of operation called "slug" or "friendly url"

here's i've done. think i've covered of "common" characters. obviously, it's going missing however.
