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.

PHP Environment Variables Manager with dotenv (.env) files and validation by example
The goal is to provide a simple way to work with environment variables
Installation
WorkFlow
Create a file named .env.example which will be shared through your dev team. This file must be commited to your repo.
Place you keys and values of your application variables.
The format is KEY=__validation-string__
For example:
There are some validators are built-in into library
Current available validators are:
-
required: value cannot be empty, can be set to any string -
number: value cannot be empty and must be convertible to an integer (is_numeric) -
boolean: value cannot be empty and must be convertible to boolean (filter_var) -
enum: value cannot be empty and should be co -
fallback:Value can be empty, but will be fallback to desired value trim:Just trims the string before set to env vars
important:
Order of validators are mandatory. They will run sequentially, passing the resulting value to the next validator, in a middleware mode. In case validator evaluates to invalid, the pipeline will be interrupted
Custom validators
You can create custom validators and feed Dotenvy with an array with key:value function name, function ref. Rules:
-
Validators must be functions with the following signature:
- You must always return a string that will be passed to next validator in validator chain/pipeline. If you pass null or empty string, the value will be ignored.
- If you want to invalidate the value, you must throw an exception and tell the user what happened.
Reference your validator in .env.example
Usage
Environment Results
After running Dotenvy, environment variables will be available through:
$_SERVER$_ENVgetenv()apache_getenv()
Important
Order of values precedence:
$_SERVER$_ENVgetenv()apache_getenv().envfile- fallback validator
- throw exception
Performance Optimization
Dotenvy can use a compiled cache file for maximum performance. The following code can be used to boost performance in production mode:
