PHP Thruway發布變量

Question

我有這個代碼。 我想做的是傳遞一個$ d變量來發布事件，有沒有辦法做到這一點，如何使用Thruway PHP發布變量數據？

$d='123';
$connection->on('open', function (\Thruway\ClientSession $session) use ($connection) {
    //publish an event
    $session->publish('com.app.deposit', ['Hello, world from PHP!!!'], ['d'=>$d], ["acknowledge" => true])->then(
        function () use ($connection) {
            $connection->close(); //You must close the connection or this will hang
            echo "Publish Acknowledged!\n";
        },
        function ($error) {
            // publish failed
            echo "Publish Error {$error}\n";
        }
    );
  });

 $connection->open();

知道了 只需使用

$connection->on('open', function (\\Thruway\\ClientSession $session) use ($connection,$d) {
