Reagordi Serializable Closure

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

Requirements

• PHP 8.2 or higher.

Installation

The package could be installed with composer:

composer require reagordi/serializable-closure

General usage

You may serialize a closure this way:

use Reagordi\Component\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.
