🧼 String Sanitizer for Laravel
==============================

[](#-string-sanitizer-for-laravel)

Sanitize strings and protect your Laravel application from Cross-site Scripting (XSS) attacks using global helper functions.

This package provides:

- 🔒 HTML-safe string sanitization using [HTMLPurifier](https://github.com/ezyang/htmlpurifier)
- ⚙️ Laravel-ready auto-discovery and registration
- 🧩 Easy-to-use global helper functions
- 📦 Composer support (private GitHub repo or public Packagist)

---

🚀 Installation
--------------

[](#-installation)

### Option 1: From Packagist (Public)

[](#option-1-from-packagist-public)

```
composer require composer require prash/string-sanitizer
```

### Option 2: From Private GitHub Repository

[](#option-2-from-private-github-repository)

Add the repository to your Laravel app’s `composer.json`:

```
"repositories": [
    {
        "type": "vcs",
        "url": "https://github.com/iamprashanta/string-sanitizer"
    }
],
"require": {
    "prash/string-sanitizer": "dev-main"
}
```

Then run:

```
composer update
```

---

📂 Package Structure
-------------------

[](#-package-structure)

```
packages/
└── prash/
    └── string-sanitizer/
        ├── src/
        │   ├── StringSanitizerServiceProvider.php
        │   └── helpers.php
        └── composer.json

```

---

🔧 Laravel Auto-Discovery
------------------------

[](#-laravel-auto-discovery)

Laravel 5.5+ will auto-discover and register this package. No need to manually add the service provider.

For Laravel <5.5, add the provider manually to `config/app.php`:

```
'providers' => [
    Prash\StringSanitizer\StringSanitizerServiceProvider::class,
],
```

---

🧼 Usage
-------

[](#-usage)

After installation, the following global helper function will be available:

```
sanitize_string($string);
```

### Example

[](#example)

```
$name = 'alert("xss")John Doe';
$safeName = sanitize_string($name);

// Output: 'John Doe'
```

---

🧪 Test in Tinker
----------------

[](#-test-in-tinker)

```
php artisan tinker
>>> sanitize_string('Helloalert(1)');
=> "Hello"
```

---

⚙️ Optional: Auto-Sanitize in Form Requests
-------------------------------------------

[](#️-optional-auto-sanitize-in-form-requests)

To automatically sanitize user input before validation:

In `AppServiceProvider`:

```
public function boot()
{
    \Illuminate\Support\Facades\Validator::extend('clean_string', function ($attribute, $value, $parameters, $validator) {
        return $value === sanitize_string($value);
    });
}
```

Then use it in your validation rules:

```
'comment' => 'required|clean_string',
```
