Simple PHP JWT

The library serves a single purpose: making JWT easier to work with.

Requirements

• PHP 7.4 or higher.

Installation

Run this command to install the library via Composer:

composer require sergeymitr/simple-php-jwt

Usage

Creating and Encoding the Token

Use Token::create() factory method to create a new token:

use Sergeymitr\SimpleJWT\Token;

$token = Token::create();

The token doesn't hold any data, so we'll need to fill that out:

$token->setIssuer('Sergeymitr\SimpleJWT')
    ->setSubject('Test Sample')
    ->setAudience('PHPUnit')
    ->setExpiration(new \DateTime('2020-02-02'))
    ->setNotBefore(new \DateTime('2020-01-01'))
    ->setIssuedAt(new DateTime('2020-01-15'))
    ->setID('sample-id');

All the data is optional, you only fill out what you need. These methods define the claim names described by RFC 7519.

You can also add custom values to your token:

$token->setCustomPayload('key', 'value');

To encode the token you will need use the Token object, and a secret string to encode it with.

use Sergeymitr\SimpleJWT\Encoder;

$encoded_token = Encoder::do($token, 'secret');

The $encoded_token will contain a string representation of the encoded and encrypted token.

Decoding the Token

To decode the token you'll need the string representation of the token, and the secret string you encoded it with:

use Sergeymitr\SimpleJWT\Decoder;

$token = Decoder::do($encodedToken, 'secret');

The Token object provides a number of "getter" methods you can use to retrieve the values, which you can review in the interface TokenInterface.
