Wrote the PHP SDK for v2
Just include the api class and initiate the class:
<?php
include('library/BoxAPI.class.php');
$client_id = 'CLIENT ID';
$client_secret = 'CLIENT SECRET';
$redirect_uri = 'REDIRECT URL';
$box = new Box_API($client_id, $client_secret, $redirect_uri);
if(!$box->load_token()){
if(isset($_GET['code'])){
$token = $box->get_token($_GET['code'], true);
if($box->write_token($token, 'file')){
$box->load_token();
}
} else {
$box->get_code();
}
}
// User details
$box->get_user();
?>
