PHP Configuration

Configuration module for PHP that supports multiple application stages like dev, prod or something else and overrides the defaults stage.

Installation

composer require spacetab-io/configuration

Versions map

• Package with version 4.* requires PHP >= 8.1
• Package with version 3.* requires PHP >= 7.4 <= 8.0
• Package with version 2.* requires PHP < 7.4

Usage

By default, path to configuration directory and application stage loading from /app/configuration with local stage.

1. Simple

<?php
use Spacetab\Configuration\Configuration;

$conf = new Configuration();
$conf->load();

var_dump($conf->all()); // get all config
echo $conf->get('foo.bar'); // get nested key use dot notation
echo $conf['foo.bar']; // the same, but use ArrayAccess interface.

Supported dot-notation syntax with an asterisk in get method. You can read about it here: https://github.com/spacetab-io/obelix-php

2. If u would like override default values, you can pass 2 arguments to class constructor or set up use setters.

<?php
use Spacetab\Configuration\Configuration;

$conf = new Configuration(__DIR__ . '/configuration', 'test');
$conf->load();

$conf->get('key'); // full example on the top

3. If the operating system has an env variables CONFIG_PATH and STAGE, then values for the package will be taken from there.

export CONFIG_PATH=/configuration
export STAGE=prod

<?php
use Spacetab\Configuration\Configuration;

$conf = new Configuration();
$conf->load(); // loaded files from /configuration for prod stage.

$conf->get('key'); // full example on the top

4. If u want to see logs and see how load process working, pass you application logger to the following method:

<?php
use Spacetab\Configuration\Configuration;

$conf = new Configuration();
$conf->setLogger($monolog); // PSR compatible logger.
$conf->load();

$conf->get('key'); // full example on the top

If you want you can use this package for logs:

composer require spacetab-io/logger

That all.

CLI utility

Also, you can install simple small cli-utility to dump total results of merged config. It is possible with multiple ways:

1. Install to /usr/local/bin as global binary

L=/usr/local/bin/st-conf && sudo curl -L https://github.com/spacetab-io/configuration-php/releases/download/2.2.0/st-conf.phar -o $L && sudo chmod +x $L

2. Install library as global composer requirements

First step:

composer global require spacetab-io/configuration-php

It will be installed to ~/.composer directory.

If you have ~/.composer/vendor/bin in globals path, you can try run command:

st-conf help dump

Otherwise, you can be register that directory:

echo 'export PATH=~/.composer/vendor/bin:$PATH' >> ~/.bash_profile
source ~/.bash_profile
