Encoding Method for URLs?

Question

Is there a method or API that WordPress uses to encode the URLs similar to how it generates part of the URL when using the title in the URL? I am writing a plugin that generates URLs and would like to use the same method as everything else is.

For instance, I type "This is my blog post" in the title and "this-is-my-blog-post" gets generated.

Answer 1

On a lower level, the function sanitize_title_with_dashes() converts to lowercase, replaces spaces and non-alphanumeric characters with dashes, and urlencodes whatever you pass to it.

<?php

echo sanitize_title_with_dashes( 'This is my blog post' );
// this-is-my-blog-post

Answer 2

Post slugs seem to be generated by wp_unique_post_slug() function (source).
