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 env
Env Manager
The Env Manager is a PHP package designed to provide a secure, flexible, and object-oriented approach to managing environment variables in PHP applications. With built-in support for whitelists and optional value encryption, this package ensures that your application handles environment variables in a secure and efficient manner.
Features
- Whitelist Management: Securely specify which environment variables are accessible, preventing unauthorized access to sensitive information.
- Optional Encryption: Encrypt environment variable values for an added layer of security, using a customizable encryption path.
- Type Conversion: Automatically convert environment variable values to their appropriate data types, including integers and booleans.
- Flexible Configuration: Easily set and update the whitelist and encryption path as per your application's requirements.
Installation
To install the Env Manager, run the following command in your project directory:
Usage
Basic Usage
With Encryption
To use the encryption feature, ensure you have set an encryption path and the Encryption class is properly configured.
Updating the Whitelist
You can update the whitelist at any time using the setWhitelist method.
Create a Convenient Wrapper
To create a function that acts as a convenient wrapper for instantiating and using your Env class, you can define a function in a global scope (or within a specific namespace if you prefer to keep things organized). This function can initialize the Env class with predefined settings like the whitelist and encryption path, and then return an instance or a specific value from the Env object.
Here's an example of how you might implement such a function:
Notes:
- Static Variable: The function uses a static variable to store the
Envinstance. This means that the sameEnvobject is reused across all calls to theenvfunction within a single request, which is efficient because it avoids the overhead of re-instantiating theEnvclass every time the function is called. - Configuration: The whitelist and encryption path are hardcoded in this example, but you might want to load these from a configuration file or environment variables to make the function more flexible and environment-specific.
- Global vs. Namespaced: Depending on your application's architecture, you might place this function in the global namespace (as shown) or within a specific namespace. If placed within a namespace, remember to reference it correctly when calling the function.
- Reusability: This approach makes it easy to fetch environment variables using the
envfunction throughout your application, leveraging the full functionality of theEnvclass with minimal boilerplate code.
This function can then be used throughout your application to fetch environment variables in a standardized way, like so:
Adjust the implementation details such as the whitelist and encryption path to suit your application's needs.
Security
The Env Manager includes a whitelist feature to ensure only predefined environment variables are accessible, adding an extra layer of security to your application. When using the encryption feature, ensure that your encryption keys are stored securely and are not accessible to unauthorized users.
