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.

- You can change a value like this :
The value is passed by reference, so, when you are using a set, your object "$o" is modified. It returns a boolean to know if the node has been modified or not
- You can add a value like this :
The parameter "key" is optional, a number will be set if you're not providing one. It returns a boolean to know if the node has been modified or not
- You can remove an attribute like this :
