Php Is
======

[](#php-is)

Is for PHP is a small library that provides some handy methods to quickly check or validate the contents of a variable.

Install it
----------

[](#install-it)

Install the library via composer:

`composer install flyandi/is`

How to use it
-------------

[](#how-to-use-it)

Pretty straightforward. The library exposes the static class `Is` that contains all the evaluating methods, e.g.:

```
$AnArray = ['red', 'blue', green];

$AnColor = '#00FF00';

if(Is::_array($AnArray)) echo "Yes, it's an array!";

if(Is::hexcolor($AnColor)) echo "This is a valid color code.";
```

Methods
-------

[](#methods)

The Is library implements the following methods currently:
