A simple library to encode and decode JSON Web Tokens (JWT) in PHP, conforming to RFC 7519.
composer require nyan02/kphp_jwt
Class JWT has property $supported_algs that lists supported algorithms.
Using property $timestamp it is possible to fix a value within testing. Defaults to PHP time() value if null.
When checking nbf, iat or expiration times, you might want to provide some extra $leeway time to account for clock skew by using leeway property.
Available functions:
JWT::encode(array $payload, string $key, string $alg, string $keyId = null, $head = null) : string
JWT::decode(string $jwt, string $key, string $alg): array
namespace nyan02\kphp_jwt;
include 'vendor/autoload.php';
$key = 'example_key';
$payload = [
'iss' => 'example.org',
'aud' => 'example.com',
'iat' => 1356999524,
'nbf' => 1357000000
];
$jwt = JWT::encode($payload, $key, 'HS256');
echo "Encode:\n" . print_r($jwt, true) . "\n";
$decoded = JWT::decode($jwt, $key, 'HS256');
var_dump($decoded);
/**
* You can add a leeway to account for when there is a clock skew times between
* the signing and verifying servers. It is recommended that this leeway should
* not be bigger than a few minutes.
*/
JWT::$leeway = 60; // $leeway in seconds
$decoded = JWT::decode($jwt, $key, 'HS256');

Install KPHP from the Docker registry by executing the following command:
docker pull vkcom/kphp
Run the container vkcom/kphp:
docker run -ti -v ~/[Your_Directory]/:/tmp/dev:rw -p 8080:8080 vkcom/kphp
Then just compile my.php and run the server — inside Docker:
kphp /tmp/dev/[Your_File_Name].php
./kphp_out/server -H 8080 -f 1
