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 *****.

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);

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