## Introduction

> This project is a fork of the excellent [opis/closure: 3.x](https://github.com/opis/closure) package. At Laravel, we decided to fork this package as the upcoming version [4.x](https://github.com/opis/closure) is a complete rewrite on top of the [FFI extension](https://www.php.net/manual/en/book.ffi.php). As Laravel is a web framework, and FFI is not enabled by default in web requests, this fork allows us to keep using the `3.x` series while adding support for new PHP versions.

Laravel Serializable Closure provides an easy and secure way to **serialize closures in PHP**.

## Official Documentation

### Installation

> **Requires [PHP 7.4+](https://php.net/releases/)**

First, install Laravel Serializable Closure via the [Composer](https://getcomposer.org/) package manager:

```bash
composer require laravel/serializable-closure
```

### Usage

You may serialize a closure this way:

```php
use Laravel\SerializableClosure\SerializableClosure;

$closure = fn () => 'james';

// Recommended
SerializableClosure::setSecretKey('secret');

$serialized = serialize(new SerializableClosure($closure));
$closure = unserialize($serialized)->getClosure();

echo $closure(); // james;
```

### Caveats

* Anonymous classes cannot be created within closures.
* Attributes cannot be used within closures.
* Serializing closures on REPL environments like Laravel Tinker is not supported.
* Serializing closures that reference objects with readonly properties is not supported.
