This project is a fork of the excellent opis/closure: 3.x package. At Laravel, we decided to fork this package as the upcoming version 4.x is a complete rewrite on top of the FFI extension. 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.xseries while adding support for new PHP versions.
Laravel Serializable Closure provides an easy and secure way to serialize closures in PHP.
Requires PHP 7.4+
First, install Laravel Serializable Closure via the Composer package manager:
composer require laravel/serializable-closure
You may serialize a closure this way:
use Laravel\SerializableClosure\SerializableClosure; $closure = fn () => 'james'; // Recommended SerializableClosure::setSecretKey('secret'); $serialized = serialize(new SerializableClosure($closure)); $closure = unserialize($serialized)->getClosure(); echo $closure(); // james;
Creating anonymous classes within closures is not supported.
