## 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.
