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 ---------------------- [](#official-documentation) ### Installation [](#installation) > **Requires [PHP 7.4+](https://php.net/releases/)** First, install Laravel Serializable Closure via the [Composer](https://getcomposer.org/) package manager: ``` composer require laravel/serializable-closure ``` ### Usage [](#usage) 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; ``` ### Caveats [](#caveats) - Serializing closures on REPL environments like Laravel Tinker is not supported. - Multiple closures defined on the same source line with identical signatures may not be distinguishable after serialization. Place each closure on its own line to avoid this. Contributing ------------ [](#contributing) Thank you for considering contributing to Serializable Closure!
