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。
