Serializable closures
|
|
---------------------
|
|
**Opis Closure** is a library that aims to overcome PHP's limitations regarding closure
|
|
serialization by providing a wrapper that will make all closures serializable.
|
|
|
|
**The library's key features:**
|
|
|
|
- Serialize any closure
|
|
- Serialize arbitrary objects
|
|
- Doesn't use `eval` for closure serialization or unserialization
|
|
- Works with any PHP version that has support for closures
|
|
- Supports PHP 7 syntax
|
|
- Handles all variables referenced/imported in `use()` and automatically wraps all referenced/imported closures for
|
|
proper serialization
|
|
- Handles recursive closures
|
|
- Handles magic constants like `__FILE__`, `__DIR__`, `__LINE__`, `__NAMESPACE__`, `__CLASS__`,
|
|
`__TRAIT__`, `__METHOD__` and `__FUNCTION__`.
|
|
- Automatically resolves all class names, function names and constant names used inside the closure
|
|
- Track closure's residing source by using the `#trackme` directive
|
|
- Simple and very fast parser
|
|
- Any error or exception, that might occur when executing an unserialized closure, can be caught and treated properly
|
|
- You can serialize/unserialize any closure unlimited times, even those previously unserialized
|
|
(this is possible because `eval()` is not used for unserialization)
|
|
- Handles static closures
|
|
- Supports cryptographically signed closures
|
|
- Provides a reflector that can give you information about the serialized closure
|
|
- Provides an analyzer for *SuperClosure* library
|
|
- Automatically detects when the scope and/or the bound object of a closure needs to be serialized
|
|
in order for the closure to work after deserialization

## Documentation
|
|
|
|
The full documentation for this library can be found [here][documentation].
|
|
|
|
## License
|
|
|
|
**Opis Closure** is licensed under the [MIT License (MIT)][license].
|
|
|
|
## Requirements
|
|
|
|
* PHP ^5.4 || ^7.0 || ^8.0
|
|
|
|
## Installation
|
|
|
|
**Opis Closure** is available on [Packagist] and it can be installed from a
|
|
command line interface by using [Composer].
|
|
|
|
```bash
|
|
composer require opis/closure
|
|
```
|
|
|
|
Or you could directly reference it into your `composer.json` file as a dependency
|
|
|
|
```json
|
|
{
|
|
"require": {
|
|
"opis/closure": "^3.5"
|
|
}
|
|
}
|
|
```
|
|
|
|
### Migrating from 2.x
|
|
|
|
If your project needs to support PHP 5.3 you can continue using the `2.x` version
|
|
of **Opis Closure**. Otherwise, assuming you are not using one of the removed/refactored classes or features(see
|
|
[CHANGELOG]), migrating to version `3.x` is simply a matter of updating your `composer.json` file.
|
|
|
|
### Semantic versioning
|
|
|
|
**Opis Closure** follows [semantic versioning][SemVer] specifications.
|
|
|
|
### Arbitrary object serialization
|
|
|
|
We've added this feature in order to be able to support the serialization of a closure's bound object.
|
|
The implementation is far from being perfect, and it's really hard to make it work flawless.
|
|
We will try to improve this, but we can't guarantee anything.
|
|
So our advice regarding the `Opis\Closure\serialize|unserialize` functions is to use them with caution.
