Binary Rules Evaluator
======================

[](#binary-rules-evaluator)

Purpose
-------

[](#purpose)

Evaluate set of conditions avoiding redundant `if/else` statements.

How it works
------------

[](#how-it-works)

Having the following table:

Condition1Condition2Condition2**Result1**truefalsefalse**Result2**falsetruetrue**Result3**nulltruefalse**Result3**truenullfalse---

We translate that table into an array

```
$rulesTable = [
    'Result1' => [
        [
            'Condition1' => true,
            'Condition2' => false,
            'Condition3' => false
        ],
    ],
    'Result2' => [
        [
            'Condition1' => false,
            'Condition2' => true,
            'Condition3' => true
        ],
    ],
    'Result3' => [
        [
            'Condition1' => null,
            'Condition2' => true,
            'Condition3' => false
        ],
        [
            'Condition1' => true,
            'Condition2' => null,
            'Condition3' => false
        ],
    ],
];
```

Having as example the following inputs:

```
$input1 = [true, null, false] //matches Result3
$input2 = [null, null, false] //matches none
```

The validator will return the condition label or false if none matches. The `null` was added to represent unknown values and will not be evaluated.

```
$binaryRulesEvaluator = (new BinaryRulesEvaluator())
    ->setRulesTable($rulesTable);

$binaryRulesEvaluator->evaluate($input1); // 'Result3'
$binaryRulesEvaluator->evaluate($input2); // false
```

If more than one result share rules set, the method `validate`will return the first matching result.

This utility class helps to keep code consistent, clean and maintainable. Trust me, code with a lot of `if/elseif/else` statements can be really messy and hard to understand. Keep in mind almost always you would be able to turn any set of evaluations into a `true/false` table.
