Library to load, validate and cache configuration from environment variables and .env files
## Install Install via composer: `composer require jan-di/config` ## Usage ### Basic Usage When creating the Config Builder, specify all definitions for the config values. You can use certain type specific constraints to validate the values later. By default, values are read from the environment variables. Optionally you can enable a Dotenv Adapter to add variables from a .env file to the environment before building the config. ### Configuration Cache To improve performance and prevent that .env files are parsed on every request, the config values should be cached. This will create a compiled PHP file that holds all fetched values. This file should be cached by Opcache to optimize further. ### Validating values and default values Each Entrytype has its own set of validating rules that can be set using a fluent API. A specified value must comply to all rules, otherwise the config is not built. Note that the default value is also validated against the ruleset to ensure that its also a valid value. Every entry that does not have a default value, must be specified. Otherwise the container won't get built successfully. ### Catch Errors The container builder is designed to stop if atleast one variable is missing or has an invalid value. This assures that a successfully built config always have all needed values. The BuildException has a few methods to show summaries of all missing/invalid values in different formats. ### Export to Array You can export the values/default values to a simple array to process it further. ### Supported DotEnv adapters Currently, the following Dotenv Libraries are supported out of the box: - [vlucas/phpdotenv](https://github.com/vlucas/phpdotenv) - [symfony/dotenv](https://github.com/symfony/dotenv) - [josegonzalez/dotenv](https://github.com/josegonzalez/php-dotenv) Alternatively you can provide you own by implementing [AdapterInterface](https://github.com/jan-di/php-config/blob/main/src/Dotenv/AdapterInterface.php)
