ParamResolver is a small class to resolve parameters in configuration arrays. It's heavily inspired on [Symfony ParameterBag](src/Symfony/Component/DependencyInjection/ParameterBag/ParameterBag.php) class.

Installation
------------

[](#installation)

Install the library via composer:

`composer require susina/param-resolver`

Usage
-----

[](#usage)

In a configuration array, it can be useful to define some parameters.

A parameter is a previously defined property, put between % special character. When ParamResolver found a parameter, it simply replaces its placeholder with the previously defined value. In the following example, suppose you have a json configuration file:

```
// configuration.json
{
    "library": {
        "project": "AwesomeProject"
    },
    "paths": {
        "projectDir": "/home/%project%"
    }
}
```

First of all you have to convert it into an array, then you can resolve the parameters:

```
