本文实例讲述了laravel框架实现敏感词汇过滤功能。分享给大家供大家参考,具体如下:
最近项目有需求,要对用户的签名,回复进行敏感词检测,然后搜到了一个好用的扩展,分享给大家。
https://github.com/FireLustre/php-dfa-sensitive
通过 composer 进行安装:
1
|
composer require lustre /php-dfa-sensitive |
然后在 app 目录下创建 Services ,并添加 SensitiveWords.php

<?php namespace App\Services; use DfaFilter\SensitiveHelper; class SensitiveWords { protected static $handle = null; private function __construct() { } private function __clone() { } /** * 获取实例 */ public static function getInstance( $word_path = []) { if (!self:: $handle ) { //默认的一些敏感词库 $default_path = [ storage_path( 'dict/bk.txt' ), storage_path( 'dict/fd.txt' ), storage_path( 'dict/ms.txt' ), storage_path( 'dict/qt.txt' ), storage_path( 'dict/sq.txt' ), storage_path( 'dict/tf.txt' ), ]; $paths = array_merge ( $default_path , $word_path ); self:: $handle = SensitiveHelper::init(); if (! empty ( $paths )) { foreach ( $paths as $path ) { self:: $handle ->setTreeByFile( $path ); } } } return self:: $handle ; } /** * 检测是否含有敏感词 */ public static function isLegal( $content ) { return self::getInstance()->islegal( $content ); } /** * 敏感词过滤 */ public static function replace( $content , $replace_char = '' , $repeat = false, $match_type = 1) { return self::getInstance()->replace( $content , $replace_char , $repeat , $match_type ); } /** * 标记敏感词 */ public static function mark( $content , $start_tag , $end_tag , $match_type = 1) { return self::getInstance()->mark( $content , $start_tag , $end_tag , $match_type ); } /** * 获取文本中的敏感词 */ public static function getBadWord( $content , $match_type = 1, $word_num = 0) { return self::getInstance()->getBadWord( $content , $match_type , $word_num ); } } |
然后我们就可以在项目中,使用 SensitiveWords::getBadWord()
来获取文本中是否有敏感词。

$bad_word = SensitiveWords::getBadWord( $content ); if (! empty ( $bad_word )) { throw new \Exception( '包含敏感词:' . current( $bad_word )); } |
在 storage 目录下创建 dict 目录存放敏感词词库,bk.txt .....等等,这些词库都是我在网上下载的。

希望本文所述对大家基于Laravel框架的PHP程序设计有所帮助。
