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.
Informations about the package angela
What is Angela?
Angela is a PHP worker/microservice framework based on ZeroMQ.
A typical Angela application consists of a job-server, a client to communicate with the server and workers which do the actual jobs. Angela provides the job server, the client and an API so you can easily implement your worker processes.
Features
Job server
The job server is Angelas main process. It manages all your workers, listens for new job-requests, distributes these jobs to your workers and send back responses to the client. One server can manage multiple pools of workers and hence handle various types of jobs.
The job server will fire up worker-processes as defined in your project configuration. It will monitor the workers and for example restart processes if a worker crashes.
It is also capable of basic load-balancing so jobs will always be passed to the next idle worker.
Worker
Angela provides an API to easily build worker processes. Each worker typically does one kind of job (even though in can handle multiple types). You would than start multiple pools of worker processes which handle the different kind of jobs required in your application.
Example
Client
The client is a simple class which allows you to send commands or job-requests to the server. It can send commands, normal jobs or background-jobs.
Normal jobs are blocking as the client will wait for a response. Background jobs however are non-blocking. They will be processed by the server but the client does not wait for a response.
Example
Requirements
- PHP >= 7.0
- ZMQ PHP extension
- ev PHP extension (optional but recommand for better performance)

- php control.php start
- php control.php stop
- php control.php restart
- php control.php status
