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 will match for string that contains exactly 2 words or more:

/([a-zA-Z]+\s?\b){2,}/g you can go http://www.regexr.com/ and test it

PHP:

$string = "i dont know , do you know?";
preg_match("/([a-zA-Z]+\s?\b){2,}/", $string, $match);

echo "
";
print_r($match);
echo "
";

Note: do not use the /g in the PHP code
