CallMorph is a PHP class that provides a simple and secure interface for serializing and unserializing anonymous functions (Closures). It automatically detects the PHP version and uses the appropriate library for maximum compatibility and security, including support for a secret key when using Laravel's Serializable Closures.

composer require mjohann/call-morph
