README

ContentGuard is a robust PHP content sanitization library specifically designed for the Indonesian web ecosystem. It helps developers filter out online gambling spam (judi online), profanity, and hate speech with advanced detection capabilities.

Unlike simple string replacement tools, ContentGuard uses an intelligent Regex Engine to detect "Leet Speak" (visual masking) commonly used by spammers (e.g., detecting s10t g4c0r as slot gacor).

Features

• ✅ Smart Detection: Catch masked words like g4c0r, s.l.o.t, judi, etc.
• ✅ Pre-built Dictionary: Comes with a comprehensive database of Indonesian gambling terms and profanity.
• ✅ Laravel Ready: Includes Service Provider and Facade for seamless integration.
• ✅ Customizable: Add your own blocklist and configure strictness.
• ✅ Zero Dependencies: Lightweight and fast.

Installation

You can install the package via composer:

composer require heyitsmi/content-guard

Configuration (Laravel)

If you are using Laravel, you can publish the configuration file to customize the behavior (e.g., changing the mask character or adding custom keywords).

Run the following command:

php artisan vendor:publish --tag="content-guard-config"

This will create a config/content-guard.php file in your application.

Usage

1. Using Laravel Facade (Recommended for Laravel)

You can use the ContentGuard facade anywhere in your controllers, jobs, or blade directives.

use Heyitsmi\ContentGuard\Facades\ContentGuard;

// 1. Check if text contains bad words (returns boolean)
$isSpam = ContentGuard::hasBadWords("Ayo main s10t g4c0r hari ini!"); 

if ($isSpam) {
    return back()->withErrors(['message' => 'Your comment contains restricted content.']);
}

// 2. Sanitize text (returns clean string)
$cleanText = ContentGuard::sanitize("Jangan main judi online!");
// Output: "Jangan main **** ******!"

2. Standalone PHP Usage

If you are not using Laravel, you can instantiate the class directly.

use Heyitsmi\ContentGuard\ContentGuard;

$guard = new ContentGuard();

$input = "Situs g.a.c.o.r terpercaya";

if ($guard->hasBadWords($input)) {
    echo "Spam detected!";
}

echo $guard->sanitize($input);

How It Works

ContentGuard converts standard keywords into flexible Regex patterns based on a Substitution Map.

• Input: slot

• Regex Generated: /\b(s|5|\$|z)[\W_]*(l|1|!|\|)[\W_]*(o|0|@|ø)[\W_]*(t|7|\+)\b/i

• Matches: slot, s1ot, s.l.o.t, s-l-o-t, sl0t, etc.

Testing

To run the unit tests included in this package:

composer test
