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 data
Vox Data manipulation library
With this library you can:
- Serialize php classes into json, xml and create custom formatters
- Unserialize data into php objects (json, xml and custom formats)
- Transfer data between different data structures (from a class instance to a different class instance)
- Normalize php object into array
- Use a property accessor to access private class members
- You can do all that with extension and annotate discriminators
- It's also compatible with ocramius proxies
Usage
since this library depends on Vox\Metadata package you must obtain a MetadataFactory instance, with it you can then create a ObjectExtractor and a ObjectHydrator instance.
Given the class:
You may create your data extractor and hydrator:
To extract the data, you may use the extract method and you can provide a context to it, there's a special built in context value called extractType you can use, that will provide a property on the normalized array called type with the origin class FQCN (fully qualified class name), that may be useful on the denormalization (hydration) process.
You can hydrate the data back into a new class or a class instance:
Data bindings
You can customize the data input and output by using the @Binding and @Exclude annotations:
In this example you can have an input array containing the "first_name" field and it will be mapped to the name property, and when you extract it, the resulting array will contain this data on the "username" field. These are completely optional in case you want the same field for input and output you can pass only the source, note that 'source' is the first parameter so you can omit the param name like this .
The exclusion can also be controlled by input and output, in this case will be used on hydration and be left out on extraction.
