Dichotomic Algorithm resolver
=============================

[](#dichotomic-algorithm-resolver)

If you have to implement an algorithm that is a succession of questions which responses are true or false, you can use Algorithm resolver to help you to implement its resolution.

setup
-----

[](#setup)

`composer require frvaillant/dichotomic`

Create your algo Class
----------------------

[](#create-your-algo-class)

```
use Dichotomic\Resolver;

class BirdAlgo extends Resolver

{

}

```

Make the array representing your algorithm
------------------------------------------

[](#make-the-array-representing-your-algorithm)

This is a basic example used in order to determinate some bird species answering a few questions : Has this bird a hooked beak ? If yes is it nocturnal ? if yes has it some feather crests ? If no it is an owl.

```
use Dichotomic\Resolver;

class BirdAlgo extends Resolver

{
    private $result;

    protected $algo = [
        'hasHookedBeak' => [
            true  => [
                'isNocturnal' => [
                    true => [
                        'hasFeatherCrests' => [
                            true => 'ended:hibou',
                            false => 'ended:chouette'
                        ]
                    ],
                    false => [
                        'hasPointedWings' => [
                            true => 'ended:faucon',
                            false => 'ended:aigle'
                        ]
                    ]
                ]
            ],
            false => 'ended:null'
        ]
    ];
}
```

implement all methods you need in BirdAlgo class
------------------------------------------------

[](#implement-all-methods-you-need-in-birdalgo-class)

```
    /**
    * NOTE : all the methods listed as key in $algo array must be implemented below
     */
    protected function hasHookedBeak(): bool
    {
        return true;
    }

    protected function isNocturnal(): bool
    {
        return true;
    }

    protected function hasFeatherCrests(): bool
    {
        return false;
    }

    protected function hasPointedWings(): bool
    {
        return true;
    }

    protected function ended($result): void
    {
        $this->result = $result;
    }

    public function getResult()
    {
        return $this->result;
    }
```

Create index.php file
---------------------

[](#create-indexphp-file)

```
$algo = new BirdAlgo();
$algo->execute();
echo $algo->getResult();
```
