This is simply a list dangerous usernames that you can include in your project. It was inspired by [this article](https://www.b-list.org/weblog/2018/feb/11/usernames/).

It comes with a `composer.json` file and `DangerousUserNames` class for easy inclusion in PHP projects. But, since it is simply a *txt* file, you can use it with any platform.

Install
-------

[](#install)

Via Composer:

```
$ composer require caseyamcl/dangerous_usernames
```

Or, use whatever programming language you want to open the textfile and read the contents into a list/array (one item per line).

Usage
-----

[](#usage)

```
use DangerousUserNames\DangerousUserNames;

// string[]
$dangerousNames = new DangerousUserNames();
$dangerousNames->inList('admin');       // case-insensitive
$dangerousNames->inList('ADMIN', true); // case-sensitive
```
