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 rbac-php
Yii RBAC PHP File Storage
This package provides PHP file-based storage for RBAC (Role-Based Access Control) package.
Requirements
- PHP 8.1 or higher.
Installation
The package could be installed with Composer:
See yiisoft/rbac for RBAC package installation instructions.
General usage
The storage is suitable for authorization data that is not too big (for example, the authorization data for a personal blog system) or for fairly static RBAC hierarchy.
Authorization data is stored in PHP files. PHP should be able to read and write these files. Non-existing files will be created automatically on any write operation.
Using storages
The storages are not intended to be used directly. Instead, use them with Manager from
Yii RBAC package:
Note that it's not necessary to use both PHP storages. Combining different implementations is possible. A quite popular case is to manage items via PHP file while store assignments in database (see Cycle and Yiisoft DB implementations).
More examples can be found in Yii RBAC documentation.
File structure
In case you decide to manually edit the files, make sure to keep the following structure.
Items
Required and optional fields:
While it's recommended to maintain created and updated timestamps, if any is missing, the file modification time will be used instead as a fallback.
The structure for an item with children:
The complete example for managing posts:
Assignments
While it's recommended to maintain created timestamps, if it is missing, the file modification time will be used instead as a fallback.
Concurrency
By default, working with PHP storage does not support concurrency. This might be OK if you store its files under VCS for example. If your scenario is different and, let's say, some kind of web interface is used - then, to enable concurrency, do not use the storage directly - wrap it with decorator instead:
Note that it will have an impact on performance so don't use it unless you really have to.
Configuring file updated time
A closure can be used to customize getting file modification time:
This is useful for 2 things:
- Using for empty timestamps when files are edited manually.
- Detection of file changes when concurrency is enabled. This helps to optimize perfomance by preventing of unnecessary loads (when file contents has not been changed).
Syncing storages manually
The storages stay synced thanks to manager, but there can be situations where you need to sync them manually. One of them is editing storage manually.
Let's say PHP files are used for both items and assignments and some items were deleted.
Then related entries in assignments storage needs to be deleted as well:
When using database as a second storage, this can be done within a migration. Depending on chosen implementation, refer to either RBAC Cycle example or RBAC DB example.
