trie_filter是屏蔽敏感词的非常有用的扩展。以下是我的实践。

ubuntu1404 + php5.3.29 + libiconv-1.13.1 + libdatrie

1. 安装libiconv
   

   wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.13.1.tar.gz

   tar zxvf libiconv-1.13.1.tar.gz

   cd libiconv-1.13.1

   ./configure –prefix=/usr/local

   make
   make install

2. 安装libdatrie

   sudo apt-get update

   sudo apt-get install libdatrie-dev

3. 下载php5.3.29包编译

    ./configure --with-iconv=/usr/local/lib

4. 获取trie_filter扩展包

 git clone https://github.com/wulijun/php-ext-trie-filter.git

 编译

$ $INSTALL_PHP_PATH/bin/phpize$ ./configure --with-php-config=$INSTALL_PHP_PATH/bin/php-config --with-trie_filter=$LIB_PATH$ make$ make install

5.测试

 php -m | grep trie_filter

 php -r "var_dump(function_exists('trie_filter_save'));"
