PHP-JWT |
| 7 |
======= |
| 8 |
A simple library to encode and decode JSON Web Tokens (JWT) in PHP, conforming to [](https://tools.ietf.org/html/rfc7519RFC 7519](https://tools.ietf.org/html/rfc7519](https://tools.ietf.org/html/rfc7519). |

| 12 |
|
| 13 |
Use composer to manage your dependencies and download PHP-JWT: |
| 14 |
|
| 15 |
```bash |
| 16 |
composer require firebase/php-jwt |
| 17 |
``` |
| 18 |

Tests |
| 180 |
----- |
| 181 |
Run the tests using phpunit: |
| 182 |
|
| 183 |
```bash |
| 184 |
$ pear install PHPUnit |
| 185 |
$ phpunit --configuration phpunit.xml.dist |
| 186 |
PHPUnit 3.7.10 by Sebastian Bergmann. |
| 187 |
..... |
| 188 |
Time: 0 seconds, Memory: 2.50Mb |
| 189 |
OK (5 tests, 5 assertions) |
| 190 |
``` |
| 191 |
|
| 192 |
New Lines in private keys |
| 193 |
----- |
| 194 |
|
| 195 |
If your private key contains `\n` characters, be sure to wrap it in double quotes `""` |
| 196 |
and not single quotes `''` in order to properly interpret the escaped characters. |
