README

Write your config in .toml files (https://github.com/toml-lang/toml) and use them with https://github.com/hassankhan/config.

Toml Parser used: https://github.com/yosymfony/toml

Config

Supports overloading and uses the first passed-in file as default values.

Interpolation

Supports simple variable interpolation within the same config file:

basepath = "/var/www"
publicpath = "${basepath}/public"

<?php
$config = new Alpipego\TomlConfig\TomlConfig(['tomlfile.toml']);

$config->get('public');
// => `/var/www/public`

This is also possible with arrays. Within the same array a simple notation can be used:

[paths]
base = "/var/www"
public = "${base}/public" # /var/www/public

It's preferable to use the full variable path to avoid conflicts:

[paths]
base = "/var/www"
public = "${paths.base}/public" # /var/www/public

Recursion is possible if the previous values have been expanded:

[paths]
base = "/var/www"
public = "${paths.base}/public" # /var/www/public
assets = "${paths.public}/assets" # /var/www/public/assets

$ENV

The configuration variables are put into environment variables. Array keys (and other complex values) get expanded like:

[paths]
base = "/var/www"

[paths.app]
dir = "${paths.base}/app"

This results in

PATHS_BASE=/var/www
PATHS_APP_DIR=/var/www/app

<?php
getenv('PATHS_APP_DIR'); // '/var/www/app' 
$_ENV('PATHS_APP_DIR'); // '/var/www/app' 

Note: If an env var already exists it does not get overridden.

Write .env file

If you want to use your configuration on your command line, you can write a .env file and source it in your shell:

<?php
$config = new \Alpipego\TomlConfig\TomlConfig(['file1', 'file2']);

$config->writeEnv(__DIR__);

Notes:

• The path to the .env has to be writable by the webserver
• This file gets written on every call of the function
