I’m trying to write a simple PHP function that can take a string like
Topic: Some stuff, Maybe some more, it's my stuff?
and return
topic-some-stuff-maybe-some-more-its-my-stuff
As such:
- lowercase
- remove all non-alphanumeric non-space characters
- replace all spaces (or groups of spaces) with hyphens
Can I do this with a single regex?
Many frameworks provide functions for this
CodeIgniter:

wordpress (has many more in the code):
