Opis Closure is a PHP library that serializes closures, anonymous classes, and arbitrary data, overcoming PHP's native serialization limitations. It supports PHP 8.x syntax, circular references, custom serializers, and cryptographically signed data.

Use cases

• serialize closures in php
• serialize anonymous classes
• queue closures for later execution
• cache serializable closures
• sign serialized data cryptographically
• serialize arbitrary php objects with circular references

When to choose

• you need to serialize closures or anonymous classes in PHP 8+
• you need serialization without PHP extensions like FFI
• you need cryptographically signed serialized data
• you need debugger-friendly reconstructed closure code

When to avoid

• your project runs on PHP 7.x (use version 3.x instead)
• you only serialize plain data PHP handles natively
• you need cross-language serialization formats like JSON or protobuf
