Can I setup a PHP Twilio application server and grant push capabilities - php

Question

I currently use a Python Twilio application server and grant push capabilities to my tokens with the following lines of code:
#app.route('/accessToken')
def token():
account_sid = os.environ.get("ACCOUNT_SID", ACCOUNT_SID)
api_key = os.environ.get("API_KEY", API_KEY)
api_key_secret = os.environ.get("API_KEY_SECRET", API_KEY_SECRET)
push_credential_sid = os.environ.get("PUSH_CREDENTIAL_SID", PUSH_CREDENTIAL_SID)
app_sid = os.environ.get("APP_SID", APP_SID)
grant = VoiceGrant(
push_credential_sid=push_credential_sid,
outgoing_application_sid=app_sid
)
token = AccessToken(account_sid, api_key, api_key_secret, IDENTITY)
token.add_grant(grant)
return str(token)
Is there a way for me to do that with PHP? I have loaded Twilio dependencies with composer and can get a token just fine. I just don't know how to add push capabilities to the token. These lines currently generate tokens (but not with push capabilities):
<?php
include('./vendor/autoload.php');
include('./config.php');
include('./randos.php');
use Twilio\Jwt\ClientToken;
use Twilio\Jwt\Grants;
// choose a random username for the connecting user
$identity = $_GET['identity'];
$capability = new ClientToken($TWILIO_ACCOUNT_SID, $TWILIO_AUTH_TOKEN);
$capability->allowClientOutgoing($TWILIO_TWIML_APP_SID);
$capability->allowClientIncoming($identity);
$token = $capability->generateToken();
echo $token;
?>

Thanks to a tip from Zack with Twilio, I finally got this working!
include('./vendor/autoload.php');
include('./config.php');
include('./randos.php');
use Twilio\Jwt\AccessToken;
use Twilio\Jwt\Grants;
use Twilio\Jwt\Grants\VoiceGrant;
use Twilio\Rest\Client;
// choose a random username for the connecting user
$identity = randomUsername();
$token = new AccessToken($TWILIO_ACCOUNT_SID, $API_KEY, $API_KEY_SECRET, 3600, $identity);
$grant = new VoiceGrant();
$grant->setPushCredentialSid($PUSH_CREDENTIAL_SID);
$grant->setOutgoingApplicationSid($TWILIO_TWIML_APP_SID);
$token->addGrant($grant);
echo $token;
