FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package closure
Opis Closure
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
evalfor 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
#trackmedirective - 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

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.
Or you could directly reference it into your composer.json file as a dependency
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 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.
