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.

About the third field Identified in outputing
To be honest, not all code will be checked accurately as you expect.
Some changes will never be checked accurately, and it's has nothing to do with someone's ability or technology.
For example, unpack() changes in PHP
5.5,
it now keeps trailing NULL bytes when the "a" format code is used.
Code below:
But we can guess the value of variables, and make a level table:
| Level | Identified | Output |
|---|---|---|
| MUST affect | Yes | Yes |
| MUST NOT affect | Yes | No |
| MAY affect | No | Yes |
So, finally output
