什么是slug URL 中的 slug

标签：

How would you reference this object with a URL, with a meaningful name? You could use Article.id so the URL would look like this:

www.example.com/article/23

Or, you could reference the title like so:

www.example.com/article/The 46 Year Old Virgin

Problem is, spaces aren‘t valid in URLs, they need to be replaced by %20 which is ugly, making it the following:

www.example.com/article/The%2046%20Year%20Old%20Virgin

That‘s not solving our meaningful URL. Wouldn‘t this be better:

www.example.com/article/the-46-year-old-virgin

That‘s a slug. the-46-year-old-virgin. All letters are downcased and spaces are replaced by hyphens -. See the URL of this very webpage for an example!

 $slug = url_title($this->input->post(‘title‘), ‘dash‘, TRUE);

用于将字符串 中的所有空格替换成连接符（-），并将所有字符转换为小写。 这样其实就生成了一个 slug ，可以很好的用于创建 URI 。
