Codex:

Retrieve category based on URL containing the category slug.

Breaks the $category_path parameter up to get the category slug.

Tries to find the child path and will return it. If it doesn't find a match, then it will return the first category matching slug, if $full_match, is set to false. If it does not, then it will return null.

It is also possible that it will return a WP_Error object on failure. Check for it when using this function.
