从文本 php 中提取关键字

Question

我正在尝试从使用所见即所得的描述输入中提取相关关键字，使用多语言英语/阿拉伯语......使用以下功能，但它没有完成我想要的任务。看看我正在使用的功能：

   function extractKeyWords($string) {

     mb_internal_encoding('UTF-8');

     $stopwords = array();

     $string = preg_replace('/[\pP]/u', '', trim(preg_replace('/\s\s+/iu', '', mb_strtolower($string))));

     $matchWords = array_filter(explode(' ',$string) , function ($item) use ($stopwords) { return !($item == '' || in_array($item, $stopwords)

 || mb_strlen($item) <= 2 || is_numeric($item));});

     $wordCountArr = array_count_values($matchWords);

     // <p><p>

     arsort($wordCountArr);

     return array_keys(array_slice($wordCountArr, 0, 10));   }
