Css class Word match on preg_match

Question

I have the following regex:

\w*(\.([a-zA-Z0-9]+[-_]+)?careerfy([-_]+[a-zA-Z0-9]+)?)\w*

The above should match the css classes which include the word careerfy and it's variants:

The match 4 is not expected and not required!

I think it would be helpful if you showed a sample of the css file, so we know what else to avoid(for people like me who don't know the css format well) — Xosrov, Jun 07 '19 at 17:02
Match `careerfy` as a whole word, `\w*(\.([a-zA-Z0-9]+[-_]+)?careerfy\b([-_]+[a-zA-Z0-9]+)?)\w*`, see https://regex101.com/r/ncd4V9/4 — Wiktor Stribiżew, Jun 07 '19 at 17:07
It is not in the requirements, please add it to the question. Try `(?![^\W_])` instead of `\b`. See https://regex101.com/r/ncd4V9/5 — Wiktor Stribiżew, Jun 07 '19 at 17:11

You need a custom word boundary after the careerfy word:

\w*(\.([a-zA-Z0-9]+[-_]+)?careerfy(?![^\W_])([-_]+[a-zA-Z0-9]+)?)\w*
                                  ^^^^^^^^^^

The (?![^\W_]) will not let match careerfy if it is followed with a letter or digit.
