Laravel Profanity Filter

A powerful, flexible, and easy-to-use PHP Laravel package for detecting, filtering, and masking profanity in multiple languages. Includes advanced features such as leet speak detection, custom word lists, language auto-detection, and real-time configuration.

🚀 Features

• Multi-language support: Detects profanity in English, French, Arabic, and more
• Customizable masking: Replace profane words with your own masking character(s)
• Leet speak & substitutions: Detects obfuscated words (e.g., "f@ck", "sh!t", "d4mn")
• Custom word lists: Add or override profane words per language
• Case sensitivity: Toggle case-sensitive or insensitive detection
• Separator handling: Detects words with separators (e.g., d-a-m-n, s_h_i_t)
• Laravel integration: Seamless usage via Facade, Service Provider, and config
• Real-time configuration: Update settings and word lists at runtime
• Extensible: Easily add new languages, separators, or substitutions
• Import custom words from files: Load additional profanity words from .txt or .json files per language

🛠 Requirements

• PHP 8.0+
• Laravel 8+

Installation

Via Composer

composer require waad/laravel-profanity-filter

Publish the configuration file:

php artisan vendor:publish --tag="profanity-filter"

Publish the words (Optional) ⚠️:

php artisan vendor:publish --tag="profanity-words"

Configuration

You can configure the package by editing the profanity-filter.php file in the config directory.

Usage

Using hasProfanity method

use Waad\ProfanityFilter\Facades\ProfanityFilter;

$text = "This is a test string with some profanity like fuck and shit.";
$hasProfanity = ProfanityFilter::hasProfanity($text);

echo $hasProfanity; // true

Using filter method

use Waad\ProfanityFilter\Facades\ProfanityFilter;

$text = "This is a test string with some profanity like fuck and shit.";
$filteredText = ProfanityFilter::filter($text);

echo $filteredText; // This is a test string with some profanity like **** and ****.

Using getProfanityWords method

use Waad\ProfanityFilter\Facades\ProfanityFilter;

$text = "This is a test string with some profanity like fuck and shit.";
$profanityWords = ProfanityFilter::getProfanityWords($text);

print_r($profanityWords);
// Output: Array ( [0] => fuck [1] => shit )

Using setLanguage method

use Waad\ProfanityFilter\Facades\ProfanityFilter;

ProfanityFilter::setLanguage('en'); // default is null (auto detect language)

$text = "This is a test string with some profanity like fuck and shit.";
$filteredText = ProfanityFilter::filter($text);

echo $filteredText; // This is a test string with some profanity like **** and ****.

Using setCaseSensitive method

use Waad\ProfanityFilter\Facades\ProfanityFilter;

ProfanityFilter::setCaseSensitive(true); // default is false

$text = "This is a test string with some profanity like fuck and Fuck.";
$filteredText = ProfanityFilter::filter($text);

echo $filteredText; // This is a test string with some profanity like **** and Fuck.

Using setDetectLeetSpeak method

use Waad\ProfanityFilter\Facades\ProfanityFilter;

ProfanityFilter::setDetectLeetSpeak(true); // default is true

$text = "This is a test string with some profanity like f@ck and sh!t.";
$filteredText = ProfanityFilter::filter($text);

echo $filteredText; // This is a test string with some profanity like **** and ****.

Using setConfig method

You can update the package configuration in real time using Laravel's config() helper, or by editing the profanity-filter.php file in the config directory.

use Waad\ProfanityFilter\Facades\ProfanityFilter;

config(['profanity-filter.custom_words.en' => ['custom']]);
ProfanityFilter::setConfig(config('profanity-filter'));

$text = "This is a test string with some profanity like fuck and shit.";
$filteredText = ProfanityFilter::filter($text);

echo $filteredText; // This is a test string with some profanity like **** and ****.

Using importWordsFromFile method

You can import additional profanity words from a file (JSON or TXT) at runtime using the importWordsFromFile method. This is useful for dynamically extending the list of profane words without modifying the config file.

use Waad\ProfanityFilter\Facades\ProfanityFilter;

// Import words from a TXT file
ProfanityFilter::importWordsFromFile(storage_path('app/profanity-words.txt'), 'en');

// Import words from a JSON file
ProfanityFilter::importWordsFromFile(storage_path('app/profanity-words.json'), 'en');

$text = "This is foo and bar and alpha.";
$filteredText = ProfanityFilter::filter($text);

echo $filteredText; // This is *** and *** and *****.

Using addWords method

You can add custom profanity words in real time using the addWords method. This is useful for dynamically adding words without modifying the config file.

use Waad\ProfanityFilter\Facades\ProfanityFilter;

// Add a single word
ProfanityFilter::addWords('badword', 'en');

// Add multiple words at once
ProfanityFilter::addWords(['testword1', 'testword2'], 'en');
ProfanityFilter::addWords(collect(['testword3', 'testword4']), 'en');

$text = "This is badword and testword1 and testword3 and testword4.";
$filteredText = ProfanityFilter::filter($text);

echo $filteredText; // This is ******* and ********* and ********* and *********.

Using removeWords method

You can remove profanity words from the filter in real time using the removeWords method.

use Waad\ProfanityFilter\Facades\ProfanityFilter;

// Remove a single word
ProfanityFilter::removeWords('damn', 'en');

// Remove multiple words at once
ProfanityFilter::removeWords(['shit', 'hell'], 'en');

$text = "This is damn and shit.";
$hasProfanity = ProfanityFilter::hasProfanity($text);

echo $hasProfanity; // false

Using clearWords method

You can clear all profanity words for a specific language in real time using the clearWords method.

use Waad\ProfanityFilter\Facades\ProfanityFilter;

// Clear all words for English
ProfanityFilter::clearWords('en');

$text = "This is damn and shit.";
$hasProfanity = ProfanityFilter::hasProfanity($text);

echo $hasProfanity; // false

Using getWords method

You can retrieve all profanity words for a specific language using the getWords method.

use Waad\ProfanityFilter\Facades\ProfanityFilter;

$words = ProfanityFilter::getWords('en');

print_r($words);
// Output: Array ( [0] => damn [1] => shit [2] => ... )

Example All Methods

use Waad\ProfanityFilter\Facades\ProfanityFilter;

$text = "This is a test string with some profanity like f@ck and sh!t.";
ProfanityFilter::setLanguage('en')
    ->setDetectLeetSpeak(true)
    ->setCaseSensitive(false)
    ->addWords('customword', 'en');

ProfanityFilter::hasProfanity($text); // true
ProfanityFilter::filter($text); // This is a test string with some profanity like *@** and **!*.

// Chaining word management methods
ProfanityFilter::addWords(['word1', 'word2'], 'en')
    ->removeWords('word1', 'en')
    ->clearWords('fr');

$words = ProfanityFilter::getWords('en');
