我正在尝试从数组中调用每个字符串。但是,我正在使用此代码生成数组。
function extract_common_words($string, $stop_words, $max_count = 5) {
$string = preg_replace('/ss+/i', '', $string);
$string = trim($string); // trim the string
$string = preg_replace('/[^a-zA-Z -]/', '', $string); // Only take alphabet characters, but keep the spaces and dashes too…
$string = strtolower($string); // Make it lowercase
preg_match_all('/\b.*?\b/i', $string, $match_words);
$match_words = $match_words[0];
foreach ( $match_words as $key => $item ) {
if ( $item == '' || in_array(strtolower($item), $stop_words) || strlen($item) <= 3 ) {
unset($match_words[$key]);
}
}
$word_count = str_word_count( implode(" ", $match_words) , 1);
$frequency = array_count_values($word_count);
arsort($frequency);
//arsort($word_count_arr);
$keywords = array_slice($frequency,0);
return $keywords;
}
它返回一个我似乎无法从中获取STRINGS的数组。所以,我想基本上取结果,并将它们放在一个字符串数组的列表中,每个字符串都是单词,从最常见到最不常见的连续顺序。
