How do I regex part of url

I need help solving regex (PCRE). I want to extract the hello-world part from multiple url below. I got this so far:

^/news/(.*?)/$

https://www.example.com/news/2017-08-09/hello-world/topics/

https://www.example.com/news/2017-08-09/hello-world/gallery/

https://www.example.com/news/2017-08-09/hello-world/

But this captures 2017-08-09/hello-world/topics and I only need hello-world

You can use this regex in PCRE:

~/news/[^/]*/\K[^/]+~
  • /news/[^/]*/: Match /news/ followed by zero or more non-/ followed by /
  • \K: Forego matched information
  • [^/]+: Match one or more non-/ characters

RegEx Demo

You may also use a capturing group:

/news/[^/]*/([^/]+)

and extract capturing group #2

IF hello-world represents an unknown text and the rest is fixed, try this:

^/news/2017-08-09/(.*?)/.*$

If date is not fixed, you can specify format it is in and use that instead, for example \d{4}-\d{2}-\d{2} or whatever you need.
