A php extension to encode and decode JSON Web Tokens (JWT).
This is experimental (and dirty) implementation. Do not use it for your production environment!
Table of Contents
Make the extension:
phpize
./configure
make
make install
Add the following line to php.ini to load the extension:
extension=jwt.so
This extension supports PHP5.4 ~ 5.6. NOT support PHP7.
jwt_encode - Returns the JWT encoded string.
string jwt_encode ( mixed $payload, string $key [, string $alg = "HS256" [, array $header ]] )
-
payload(array|object): The payload being encoded. -
key(string): The secret key. If the algorithm used is asymmetric, this is the private key. -
alg(string): The signing algorithm. DefaultHS256. Now, supported algorithms are 'HS256', 'HS384' and 'HS512'. -
header(array): An array with header elements to attach.
JWT encoded string. If this function fails, it returns FALSE.
$payload = ["user_id" => "1234567890", "admin" => true];
$key = "secret";
echo jwt_encode($payload, $key);The above example will output:
eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VyX2lkIjoiMTIzNDU2Nzg5MCIsImFkbWluIjp0cnVlfQ.PfNTLhA7RRxBSDc_t4gkx9NhDJQ1DivtTGHyOywAkqY
jwt_decode — Decodes a JWT string.
mixed jwt_decode ( string $jwt, mixed $key [, bool $assoc = false [, array $allowed_algs = array("HS256") ]] )
-
jwt(string): The JWT string -
key(string|array): The key, or map of keys. If the algorithm used is asymmetric, this is the public key. -
assoc(bool): When TRUE, returned objects will be converted into associative arrays. -
allowed_algs(array): List of supported verification algorithms. DefaultHS256. Supported algorithms are 'HS256', 'HS384' and 'HS512'.
Object The JWT's payload as a PHP object or array. If this function fails or signature verification fails, it returns FALSE.
$jwt = "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VyX2lkIjoiMTIzNDU2Nzg5MCIsImFkbWluIjp0cnVlfQ.PfNTLhA7RRxBSDc_t4gkx9NhDJQ1DivtTGHyOywAkqY";
$key = "secret";
var_dump(jwt_decode($jwt, $key));The above example will output:
class stdClass#3 (2) {
public $user_id =>
string(10) "1234567890"
public $admin =>
bool(true)
}
