Introduction

This project is a fork of the excellent opis/closure: 3.x package. At Ugarit, we decided to fork this package as the upcoming version 4.x is a complete rewrite on top of the FFI extension. As Ugarit 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.

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

Official Documentation

Installation

Requires PHP 7.4+

First, install Ugarit Serializable Closure via the Composer package manager:

composer require ugarit/serializable-closure

Usage

You may serialize a closure this way:

use Ugarit\SerializableClosure\SerializableClosure;

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

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

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

echo $closure(); // james;

Caveats

Serializing closures on REPL environments like Ugarit 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.
