Regex to match 2 or more words

Question

I have a regex that tries to match for 2 or more words, but it isn\'t working as it\'s suppose to. What am I doing wrong?

$string = \"i dont know , do you know?\         


        

Answer 1

This one should work: ~([\w']+(\s+|[^\w\s])){2,}~g, which also match string like "I do!"
