Uniqe is simple library for generating unique filenames in directories.

Requirements
------------

[](#requirements)

Unique requires PHP 5.4 or later.

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

[](#installation)

The best way to install Unique is use [Composer](http://getcomposer.org) package [`rm/unique`](https://packagist.org/packages/rm/unique) or manual download the latest ZIP package from [GitHub](https://github.com/romanmatyus/Unique/archive/master.zip).

```
$ composer require rm/unique

```

Example
-------

[](#example)

I need upload file `something.png` into directory `/images`.

If it is necessary to not overwrite existing files, you need to generate unique filenames.

**Now it's simple!**

```
$filename = Unique::get('something.png', '/images'); // return 'something.png'
```

And what if directory contains files `something.png` and for example, also `something-1.png`?

Returns `something-2.png`!

`Unique::get()` automatic generate filename in format `.` and check if exists in specified directory. If is unique, return it.

API
