Remove elements of one array if it is found in another
arrays, php
Solution
You are looking for `array_diff`:
$subject = "Warmly little in before cousin as sussex...";
$tags = explode(" ", strtolower($subject));
$definite_articles = array('the','this','then','there','from','for','to','as');
$tags = array_diff($tags, $definite_articles);
print_r($tags);
See it in action.
Problem
Possible Duplicate: Remove item from array if it exists in a 'disallowed words' array I have a dynamic string that clients will send and I want to create comma delimited tags from it: ``` $subject = "Warmly little in before cousin as sussex and an entire set Blessing it ladyship."; print_r($tags = explode(" ", strtolower($subject))); ``` And yet, I want to delete a specific group of words (such as definite articles), but I want to delete the key and value of that word if it is in the exploded array: ``` $definite_articles = array('the','this','then','there','from','for','to','as','and','or','is','was','be','can','could','would','isn\'t','wasn\'t', 'until','should','give','has','have','are','some','it','in','if','so','of','on','at','an','who','what','when','where','why','we','been','maybe','further'); ``` If one of these words in the `$definite_article` array are in the `$tags` array delete the key and value of that word and the new array will have these words taken out. I will have this array be used by `array_rand` to have a random group of words chosen out of it. I've tried many things to achieve my result, but nothing so far. Can someone help me find a resolve to this?
