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 ghost
Ghost
Ghost is a small PHP utility for creating dynamic, proxy-backed objects without needing a concrete class upfront. The package is centered around four components:
- GhostFunction: defines dynamic methods and properties using closures and simple array definitions.
- GhostDraft: a lightweight bridge that exposes the proxy id and the underlying GhostFunction payload.
- GhostProxy: creates a proxy object and maps it to a concrete class or anonymous object.
- GhostClass: a convenience base class that automatically performs the GhostProxy mapping and exposes a protected proxy object for initialization.
Installation
GhostFunction
GhostFunction lets you create callable members dynamically. It accepts an array of names and optional property values. Methods are registered by calling their name as a method and passing a closure. Properties are defined by passing an array entry with a single key/value pair.
Useful helpers:
GhostFunction is flexible, but it is not IDE-friendly. Use it when you want lightweight runtime behavior, or wrap it with GhostProxy and GhostClass for more structured usage.
GhostProxy
GhostProxy creates a dynamic proxy container and maps it to a class or anonymous object. The mapping callback receives a GhostDraft instance, which can be used to retrieve the proxy id and the underlying GhostFunction data.
A few important points:
- Call GhostProxy::object() immediately after GhostProxy::new() to retrieve the mapped object.
- The mapping callback is responsible for creating the final object instance.
- GhostProxy::map() is used internally by GhostClass to connect the proxy state with the mapped object.
GhostDraft
GhostDraft is the minimal abstraction used by GhostProxy to hand a mapped object the proxy identity and its GhostFunction payload.
In practice, you rarely need to implement GhostDraft yourself. GhostProxy builds a compatible instance and passes it into the mapping callback.
GhostClass
GhostClass is the recommended base class when you want a clean and structured way to use GhostProxy. Its constructor is final, so child classes should implement ghostInit() instead of overriding the constructor.
Notes about GhostClass
- The protected property proxy is created automatically during construction.
- The proxy is available inside ghostInit() and remains intact during initialization.
- The proxy property should not be overwritten manually.
Summary
If you want a lightweight runtime-only API, use GhostFunction. If you want a cleaner object-oriented integration with IDE-aware usage, prefer GhostProxy together with GhostClass.
