可否添加下词替换方法,检测到词后替换成*或自定义字符

[huizhang001]

目前只提供了检测功能，检测结果提供了位置和词的长度，直接替换就行了！

我今天搞了一个

    /**
     * 检测内容违规信息
     * @param string $content
     * @param int $timeout
     * @return array
     */
    public static function checkWordsMatch(string $content, $timeout = 3): array
    {
        try {
            return WMServer::getInstance()->detect($content, $timeout);
        } catch (\Throwable $e) {
            return [];
        }
    }

    /**
     * 将违规内容替换
     * @param string $content
     * @param string $repeat
     * @return string
     */
    public static function repeatWordsMatch(string $content, string $repeat = '*'): string
    {
        $result = self::checkWordsMatch($content);
        foreach ($result as $res){
            $location = $res->getLocation()[0];
            $len = $location['length'];
            $rep = str_repeat($repeat, $len);
            foreach ($location['location'] as $start){
                $content = mb_substr_replace($content, $rep, $start , $len);
            }
        }
        return $content;
    }

得在bootstrap放上这个函数

if (function_exists('mb_substr_replace') === false) {
    /**
     * @param $string
     * @param $replacement
     * @param $start
     * @param null $length
     * @param null $encoding
     * @return string
     */
    function mb_substr_replace($string, $replacement, $start, $length = null, $encoding = null): string
    {
        $string_length = (is_null($encoding) === true) ? mb_strlen($string) : mb_strlen($string, $encoding);

        if ($start < 0) {
            $start = max(0, $string_length + $start);
        } else if ($start > $string_length) {
            $start = $string_length;
        }

        if ($length < 0) {
            $length = max(0, $string_length - $start + $length);
        } else if ((is_null($length) === true) || ($length > $string_length)) {
            $length = $string_length;
        }

        if (($start + $length) > $string_length) {
            $length = $string_length - $start;
        }

        if (is_null($encoding) === true) {
            return mb_substr($string, 0, $start) . $replacement . mb_substr($string, $start + $length, $string_length - $start - $length);
        }

        return mb_substr($string, 0, $start, $encoding) . $replacement . mb_substr($string, $start + $length, $string_length - $start - $length, $encoding);

    }
}
