$accessKey = 'j4jIdbq59JsF2f4CXwwkIiVHNFnyNvWXqMqXxcIbQDqFRz5K0fe9e3QfqjKwvW3O';
$client = new EventClient($accessKey, 'http://localhost:7070');

Set a User Record from Your App

// assume you have a user with user ID 5
$response = $client->setUser(5);

Set an Item Record from Your App

// assume you have a book with ID 'bookId1' and we assign 1 as the type ID for book
$response = $client->setItem('bookId1', array('itypes' => 1));

Import a User Action (View) form Your App

// assume this user has viewed this book item
$client->recordUserActionOnItem('view', 5, 'bookId1');

Retrieving Prediction Result

// assume you have created an itemrank engine on localhost:8000
// we try to get ranking of 5 items (item IDs: 1, 2, 3, 4, 5) for a user (user ID 7)

$engineClient = new EngineClient('http://localhost:8000');
$response = $engineClient->sendQuery(array('uid'=>7, 'iids'=>array(1,2,3,4,5)));

print_r($response);
