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.

Installation
Usage
Require properties
When declaring required properties, the dto will validate all parameters against the declared properties. Take a look at the validation table for more details.
bssphp\dto\Exceptions\InvalidDataException: The required property `name` is missing
Array methods
Simple array representation
To get an array representation of the dto, simply call the toArray instance method.
When transferring the dto properties to an array format, the package will respect and call any toArray methods of nested dto instances or otherwise fall back to any declared jsonSerialize method when implementing the JsonSerializable interface.
Convert keys
The toArrayConverted method allows the simple conversion of property keys to a given case.
Flexible dtos
When attaching the Flexible attribute you can provide more parameters than declared in the dto instance.
All properties will also be included in the toArray methods. This would otherwise throw an InvalidDataException.
