Translate post title to something url-firendly
<p>I have a site where people post stories, and I want part of each stories title to be included in the url that points to the story.</p>

<p>For example if a poster posts a story titled "this is an example post", I am looking for a way to translate it to "this-is-an-example-post".</p>

<p>Also, because the title will be used in a URL I need to filter out all the reserved or potentially dangerous characters.</p>

<p>Is there an already made way (function library whatever) to do that or I will have to write my own?</p>
