A PHP extension for JSON Web Token (JWT)

Requirement

• PHP 7 +
• OpenSSL (Version >= 1.0.1f) Might work with older version as well, but I did not check that.

Install

$ git clone https://github.com/cdoco/php-jwt.git
$ cd php-jwt
$ phpize && ./configure --with-openssl=/path/to/openssl
$ make && make install

Quick Example

$key = "example_key";
$claims = array(
    "data" => [
        "name" => "ZiHang Gao",
        "admin" => true
    ],
    "iss" => "http://example.org",
    "sub" => "1234567890",
);

// default HS256 algorithm
$token = jwt_encode($claims, $key);

echo $token . PHP_EOL;
//eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.

print_r(jwt_decode($token, $key));
/**

    [data] => Array
        (

            [admin] => 1
        )

    [iss] => http://example.org
    [sub] => 1234567890
)
