📂 Usage
-------

[](#-usage)

[](#basic-detection)

use ProfanityFilter\ProfanityFilter;

$filter = new ProfanityFilter('en');

$text = "You idiot!";

if ($filter->containsProfanity($text)) {
    echo "Profanity detected!";
}
```

### Censor Words

[](#censor-words)

```
$censored = $filter->censor("You dumb bastard!");
echo $censored; // You **** *******!
```

### Get Detected Words

[](#get-detected-words)

print_r($words); // ['stupid', 'shitty']
```

[](#use-multiple-languages)

🧪 Running Tests
---------------

[](#-running-tests)

```
vendor/bin/phpunit tests/
```

Make sure you’ve run:

```
composer dump-autoload
```

to register autoload-dev.

---

📁 Language Wordlist Files
-------------------------

[](#-language-wordlist-files)

Each language is stored in a separate JSON file in `src/data/`, e.g.:

```
src/data/en.json
src/data/ru.json
src/data/zh.json

```

You can extend these manually or via the library methods.
