Jason, Thanks, that works except that it doesn't account for case. I want to ignore case as it doesn't apply here. But I was able to get rid of the associative array. So I reckoned it best to LC the question and copy it because I want to return the original question as is back to the browser. $_string = strtolower ($Config['input']['question']); $words = explode(" ",$_string); $ignoreWords = array('brazil','like','the','this','that','why','are','there','where','find',); $FindTheseWords = array_diff($words, $ignoreWords); Peter
