Question

I want to test a string to see it contains certain words.

i.e:

$string = "The rain in spain is certain as the dry on the plain is over and it is not clear";
preg_match('`\brain\b`',$string);

But that method only matches one word. How do I check for multiple words?

Answer 1

Something like:

preg_match_all('#\b(rain|dry|clear)\b#', $string, $matches);
