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.

Exceptions

Configuration file
This is a sample configuration file, it is usually stored in config/session.php.
DI service
The session is created as a framework service within $di. The following is a sample on how the session service is created.
The session can always be active, in the default configuration file this is depending on the PHP define ANAX_WITH_SESSION which is usually set in config/commons.php which is available from the module anax/commons.
The session is always started when ANAX_WITH_SESSION is defined and true.
This is how the callback works, when it creates the session service.
- The object is created.
- The configuration file, usually
config/session.php, is read. - The session is named.
- The session is created.
The service is lazy loaded and not created until it is used. However, it is always loaded when "active" => true.
Access as framework service
You can access the module as a framework service.
Start the session
The recommended way, and the default behaviour, is to start the session by defining ANAX_WITH_SESSION and set it to true. This is usually done in config/commons.php which source is available in the module anax/commons.
Setting ANAX_WITH_SESSION to false means that the session is not started by default.
As an alternative, you can start the session anywhere by activating (using) the di service. A good place to do this is in the frontkontroller index.php, after you have created $di (and $app). The session will then be available for all page requests.
The session will not start when running in CLI (for example PHPUnit), however, it will still be active and usable as means of unit testing.
Work with session variables
There are helpers to use when reading and setting values in the session.
Session flash messages
There is feature useful for flash messages. A value is retrieved from the session and is then deleted.
Debug the session
You can var_dump the session object and it will print out the content of $_SESSION.
Destroy the session
You can destroy the session which might be useful during development.
