PHP actually does not support [function overloading](https://en.wikipedia.org/wiki/Function_overloading), as functions distinguished but name only. This is a class that helps to imulate function overloading in PHP.

General usage
-------------

[](#general-usage)

Function cases provided as an array of callables, where key is a signature of parameters types.

### 1. Simple signature:

[](#1-simple-signature)

Parameters signature is a list of types separeted by comma.

```
    $func = new OverloadedFunction([
        'integer, integer' => function ($a, $b) { return $a + $b; },
        'string, string' => function ($a, $b) { return $a . $b; }
    ]);

    var_dump($func(1, 1)) // => 2
    var_dump($func('1', '1')) // => '11'
```

### 2. Union types:

[](#2-union-types)

Sometimes your parameter need to be of a kind, that implements not one interface, but several.

```
    $func = new OverloadedFunction([
        'ArrayAccess&Countable' => function ($i) { return true; }
    ]);

    var_dump($func(new ArrayIterator)) // => bool(true)
```

### 3. Intersection types:

[](#3-intersection-types)

Sometimes you allow parameter to be not of one type, but of several types.

```
    $func = new OverloadedFunction([
        'string|integer' => function ($i) { return true; }
    ]);

    var_dump($func(1)) // => bool(true)
    var_dump($func('1')) // => bool(true)
```

### 4. Typed arrays:

[](#4-typed-arrays)

You can restrict your parameter to be an array of elements of certain types.

```
    $func = new OverloadedFunction([
        'integer[]' => function ($arr) { return 'integer'; },
        'integer|string[]' => function ($arr) { return 'mixed'; }
    ]);

    var_dump($func([1, 2, 3])) // => string(7) "integer"
    var_dump($func([1, 2, '3'])) // => string(5) "mixed"
```

### 5. Optional parameters:

[](#5-optional-parameters)

Sometimes you allow parameter to be optional. Make sure you provide default values for such cases.

```
    $func = new OverloadedFunction([
        '?integer' => function ($i = 1) { return $i; }
    ]);

    var_dump($func(1)) // => bool(true)
    var_dump($func()) // => bool(true)
```
