This project is a fork of the excellentopis/closure: 3.x package. At Laravel, we decided to fork this package as the upcoming version4.x is a complete rewrite on top of theFFI extension. As Laravel is a web framework, and FFI is not enabled by default in web requests, this fork allows us to keep using the3.x series while adding support for new PHP versions.

Laravel Serializable Closure provides an easy and secure way toserialize closures in PHP.

RequiresPHP 7.4+

First, install Laravel Serializable Closure via theComposer package manager:

composer require laravel/serializable-closure

You may serialize a closure this way:

useLaravel\SerializableClosure\SerializableClosure;$closure =fn () =>'james';// RecommendedSerializableClosure::setSecretKey('secret');$serialized =serialize(newSerializableClosure($closure));$closure =unserialize($serialized)->getClosure();echo$closure();// james;

• 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.
