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.

PHP Tail Library
A PHP Library for tailing files, supporting PHP 7.0 and above.
Currently, this library allows you to get the tail of a given file. Subsequent calls to the ` function will return whatever has been appended since the last call.

- If a file is over-written and therefore has less than the amount of lines than it started with; the entire new file will be returned at the next ` call.
- Obviously you need to have your own polling/monitoring to decide when to call `
