我正在嘗試從使用所見即所得的描述輸入中提取相關關鍵字，使用多語言英語/阿拉伯語......使用以下功能，但它沒有完成我想要的任務。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)); }

function generateKeywords($str)
{
$min_word_length = 3;
$avoid = ['the','to','i','am','is','are','he','she','a','an','and','here','there','can','could','were','has','have','had','been','welcome','of','home',' ','“','words','into','this','there'];
$strip_arr = ["," ,"." ,";" ,":", "\"", "'", "“","”","(",")", "!","?"];
$str_clean = str_replace( $strip_arr, "", $str);
$str_arr = explode(' ', $str_clean);
$clean_arr = [];
foreach($str_arr as $word)
{
if(strlen($word) > $min_word_length)
{
$word = strtolower($word);
if(!in_array($word, $avoid)) {
$clean_arr[] = $word;
}
}
}
return implode(',', $clean_arr);
}
