Regex word match from two groups

Question

My requirement is, I want to match words in a sentence from two groups of words, say the sentence should contain at least one word from group 1 and at least 1 from group 2 as well.

The sentence can be - Ronaldo is the highest paid player in Football.

What could be the possible regex for this, language is php.

I tried

(?=.*\b(cat|dog|rat)\b)(?=.*\b(blue|black|red)\b).*$ It works but is case sensitive.

I tried this - (cat|dog|rat)(black|red|blue) Expected output sentence is - The cat and dogs are black. — AbhikM, Jul 24 '19 at 06:46
Does the instance of the firs group will be first too in the sentence? — , Jul 24 '19 at 07:00
No, order can be anything, I just need to match at least one word from two sets. — AbhikM, Jul 24 '19 at 07:11

Try to use 2 regexes, one per group, and then checkfor 2 matches:

For example:

Forst regex: /(Football)|(Hockey)|(Cricket)/i

Second regex: /(Ronaldo)|(Messi)|(Kohli)|(Jordan)/i

Demo for the First Regex

The Capital letters can be just in the beginning of the word? – Jul 24 '19 at 08:26
