For example, I have a string "xxxABCDExxx", and I have two keywords "ABC" and "CDE", now I want get "ABC" and "CDE" from string.

In php, preg_match_all('/(ABC|CDE)/'.. will only match ABC or CDE, but not both.

Is there any way to match keywords even they're adjacent and share the same word.

What environment and tools are you using? Not all flavors of regex are created equal. – Gary_W May 14 '21 at 17:15
@Gary_W I used PHP language. – Pader May 14 '21 at 17:19

@LucasMendonça No, it's not, because `/b` or `Positive Lookahead` divide them with different things like `not a-z0-9`. – Pader May 14 '21 at 17:31

@Pader Afaik [capturing inside a lookahead](https://stackoverflow.com/q/11430863/5527985) is only way for overlapping matches: [`(?=(ABC|CDE))`](https://regex101.com/r/ZY7XYL/1) – bobble bubble May 14 '21 at 17:43
