FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

构建敏感词库树

场景一: 可以拿到不同(用户)词库数组

// 获取感词库索引数组
$wordData = array(
    '察象蚂',
    '拆迁灭',
    '车牌隐',
    '成人电',
    '成人卡通',
    ......
);

// get one helper
$handle = SensitiveHelper::init()->setTree($wordData);

场景二: 全站使用一套敏感词库

// 获取感词库文件路径
$wordFilePath = 'tests/data/words.txt';

// get one helper
$handle = SensitiveHelper::init()->setTreeByFile($wordFilePath);

设置干扰因子集合

注意只干扰因子只支持单个字符或单个汉字,暂不支持词

但是多个干扰因子连在一起,敏感词可以准确识别

$handle = SensitiveHelper::init()->setStopWordList(['&', '*', '.'])->setTreeByFile($wordFilePath);

忽略大小写

注意该设置只有在构建敏感词库树之前调用

在构建敏感词库树之后调用,结果可能不符合预期

$handle = SensitiveHelper::init()->setIgnoreCase()->setTree(['Av', '赌球网'])

检测是否含有敏感词

$islegal = $handle->islegal($content);

敏感词过滤

// 敏感词替换为*为例(会替换为相同字符长度的*)
$filterContent = $handle->replace($content, '*', true);

 // 或敏感词替换为***为例
 $filterContent = $handle->replace($content, '***');

标记敏感词

 $markedContent = $handle->mark($content, '<mark>', '</mark>');

获取文字中的敏感词

// 获取内容中所有的敏感词
$sensitiveWordGroup = $handle->getBadWord($content);
// 仅且获取一个敏感词
$sensitiveWordGroup = $handle->getBadWord($content, 1);

使用composer自动加载php命名空间
