Convert input to alias

[eluser]Iwasignited[/eluser]
Hello,
Im writing a blog application as my first PHP app with CI.
I have a question.
When the administrator posts a new entry with title, body. I want to convert the title input to alias and store it in my database in order to make the URL nicer with SEO.
For example: My First Entry -> my-first-entry or something like that.

Please help me.
Thanks.

I am telling you what to do, and you implement it .

clean your URL of ", ', 's and other buggy chars
break your url into pieces depending on  ( ) - space, explode()
foreach on your array and make a new string, by adding "-".
