PHP Regular expression to get words with repeated chars in a string

Question

I'm trying to get the words in a string with repeated chars. For example: "II loooovve this video. It's awesooooommeee."

How can I get the result: loooovve awesooooommeee ?

Try this: `.*([a-z])\\1{2,}.*` (starts matching if 3 repeated letters) — Maciej A. Czyzewski, Mar 29 '16 at 19:28

You can use this regex with a back-reference:

\b\w*(\w)\1\w*

RegEx Demo

RegEx Breakup:

\b     # word boundary
\w*    # match 0 or more word characters
(\w)   # match a single word char and capture it as group #1
\1     # back-reference to captured group #1 to make sure we have a *repeat*
\w*    # match 0 or more word characters

btw it will also match II since it has a repeating character I.

It's not working... it match for example word: _vidieo_ (two __i__ letters) – Maciej A. Czyzewski Mar 29 '16 at 19:34

Pattern for matching all words with 3+ repeated letters:

\b\w*(\w)\1{2}\w*

II loooovve this video. It's awesooooommeee.
