PHP Data type assertions.

---

This package provides helper methods to validate variable data type. While there are handy native methods like `is_string()` or `is_array()`, you can have then check for single type at a time. This package allows to validate against type union (i.e. `STRING|INT`) or ensure that priovided `string` refers to existing class. Also, contrary to native methods, if there's no match and variable contains data of non-welcomed type, exception is thrown which lets you simplify your code flow.

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

[](#installation)

```
composer require --dev marcin-orlowski/type-asserts
```

---

Usage example
-------------

[](#usage-example)

The following code ensures `$var` is of either `int` or `float` type before math is done:

```
use MarcinOrlowski\TypeAsserts\Type;
use MarcinOrlowski\TypeAsserts\Validator;

$var = 'foo';

Validator::assertIsType($var, [Type::INT, Type::FLOAT]);
$result = $var * 5;
```

The following code ensures `$var` refers to existing class, before we try to instantiate it:

```
use MarcinOrlowski\TypeAsserts\Type;
use MarcinOrlowski\TypeAsserts\Validator;

$cls = 'non-existing';

Validator::assertIsType($cls, Type::EXISTING_CLASS);
$obj = new $cls;
```
