Use PHP extension trie_filter to filter Chinese sensitive words
1. Install libiconv, which is a dependency of libdatrie
wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz tar zxvf libiconv-1.14.tar.gz cd libiconv-1.14 ./configure make make install
2. Install: libdatrie (http://linux.thai.net/~thep/datrie/datrie.html#Download)
tar zxf libdatrie-0.2.4.tar.gz cd libdatrie-0.2.4 ./configure --prefix=/usr/local make make install
Compilation error trietool.c:125: undefined reference to `libiconv'
The solution is: ./configure LDFLAGS=-L/usr/local/lib LIBS=-liconv
3. Install the trie_filter extension
Since the official trie_filter extension does not support Chinese very well, I found an extension on git that was rewritten on the official extension and has been tested without any problems
The installation method is as follows:
https://github.com/wulijun/php-ext-trie-filter Download the source code package here
phpize ./configure --with-php-config=/usr/local/bin/php-config make make install
4. Modify the php.ini file and add the trie_filter extension :extension=trie_filter.so, restart PHP.
Check phpinfo and find that the trie_filter extension is available, as shown in the following figure:
5. Generate a dictionary for word detection, because it is not included in the source code package downloaded above. It has a command to generate a dictionary, so you also need to download the official source code package
(https://code.google.com/p/as3chat/downloads/detail?name=trie_filter-2011-03-21.tar. gz)
tar zxf trie_filter-2011.03.21.tar.gz cd trie_filter-2011.03.21 gcc -o dpp dpp.c -ldatrie // 生成dpp命令用语编译词典 ./dpp words.txt words.dic //将words.txt 编译成trie_filter使用的词典 words.txt中每个词占一行
Error when generating dictionary: ./dpp: error while loading shared libraries: libdatrie.so.1: cannot open shared object file: No such file or directory
Solution : Execute
ldconfig
and then execute
./dpp words.txt words.dic
6. Test:
<!--?php /** * trie_filter 敏感词过滤示例 * **/ // 载入词典,成功返回一个 Trie_Filter 资源句柄,失败返回 NULL $file = trie_filter_load('./words.dic'); var_dump($file); $str1 = '今天利用trie_filter做敏感词过滤示例'; $str2 = '今天利用trie_filter做过滤示例'; // 检测文本中是否含有词典中定义的敏感词(假设敏感词设定为:‘敏感词’) $res1 = trie_filter_search_all($file, $str1); // 一次把所有的敏感词都检测出来 $res2 = trie_filter_search($file, $str2);// 每次只检测一个敏感词 var_dump($res1); echo "<br/-->"; var_dump($res2); trie_filter_free($file); //最后别忘记调用free
It is recommended to use php 5.3.3 or above version, I Using 5.3.3

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4.
