Question

Here’s the problem:
I have words I entered via a textarea. I put each word in an entry. i.e words are in an array. On the other hand, I got a wordlist, in which words are separated by newline, I put each word in another array, too.

Now I want to check if $words_entered[$i] = any (and which) of the array $wordlist.

Thanks in advance!

If you want the results in the list:

$intersection = array_intersect($words_entered,explode("\n",$wordlist));

If you want the results NOT in the list:

$diff = array_diff($words_entered,explode("\n",$wordlist));
