Edit Question
Title
Body
I have an array: Array ( [0] => tom [1] => and [2] => jerry ) And I also have a disallowed words array: Array ( [0] => and [1] => foo [2] => bar ) What I need to do is remove any item in the first array that also appears in the second array, in this instance for example, key 1 would need to be removed, as 'and' is in the disallowed words array. Now I currently have this code, which does a foreach on the disallowed words and then uses array_search to find any matches: $arr=array('tom','and','jerry'); $disallowed_words=array('and','or','if'); foreach($disallowed_words as $key => $value) { $arr_key=array_search($value,$array); if($arr_key!='') { unset($search_terms[$arr_key]); } } Now I know this code sucks, what I want to know is if there is a more efficient method of removing and item from an array where it exists in another array, especially if it negates using a foreach.
