README

ParamsResolver is an utility service that uses reflection to resolve parameters for a given callable performing look-up in the following order and matched against class/interface/parameter names:

• injected parameters,
• dependencies or parameters in the injected or composed container
• default values id available in the callable

Example:

In the following example the $db dependency is fetched from the container, the $config parameter is provided and the $options parameter receives the default empty array value.

<?php

use My\Db;
use pine3ree\Container\ParamsResolver;

class MyDataMapper
{
    public function__construct(My\Db $db, array $config, array $options = [])
    {
        //...
    }
    //...
}

//...
// include the container building code/file
//...

$paramsResolver = new ParamsResolver($container);

$args = $paramsResolver->resolve([MyDataMapper::class, '__construct'], [
    'config' => [
        //..
    ],
]);

$myDataMapper = new MyDataMapper(...args);

A common usage of ParamsResolver is within a reflection based factory
