从PHP中的另一个数组或单词中删除单词数组

Question

I have an array of stop words that i would like removed from a string. But in every case the words like 'in' are being removed from valid words like climbing leaving climb g in the resulting string.

I was thinking if I could have two arrays. One array of the stop words and one array of the exploded string. Is there a quick way to use the array of stop words to compare against the array of the exploded string, thus removing all stop words from the exploded string array...

$stopwords = array( 'foo', 'bar');
$string = "foo bar Foobar";
$newArray = explode(" ", $string)

I would like the resulting $string = "Foobar"?

thanks in advance,

Marv

array_diff is your friend to eliminate the words you don't like too see:

$string = implode(" ", array_diff(explode(" ", $string), $stopwords));
