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?
You are looking for
$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);
Sounds like an easy job for
array array_diff ( array $array1 , array $array2 [, array $... ] )
array2and returns the difference.
Which basically means it will return
array1 after it’s been stripped of all values which exist in
