Q: 

Comparing and highlighting phrases in text with php

I have an array of words $duplicate_words and a string $contents. I want to search for the words in the string and highlight them when there is a match.

I can highlight single duplicate words, but I don't want to highlight single words - I want to highlight only when two or more words match there. I've been trying to find a solution for over a week without success. Any ideas?
