节俭：没有找到类'Thrift \ Transport \ TSocket'

I am following the official tutorial for a client and php server using Apache Thrift. My problem is that it does not recognize the TSocket class.

Will I have problems with the namespace?

Error:

Fatal error: Class 'Thrift\Transport\TSocket' not found in D:\Calculadora\tutorial\php\PhpClient.php on line 45

<?php

error_reporting(E_ALL);

use Thrift\ClassLoader\ThriftClassLoader;

$GEN_DIR = realpath(dirname(__FILE__).'/..').'/gen-php';

$loader = new ThriftClassLoader();
$loader->registerNamespace('Thrift', __DIR__ . '/../../lib/php/lib');
$loader->registerDefinition('shared', $GEN_DIR);
$loader->registerDefinition('tutorial', $GEN_DIR);
$loader->register();

try {
  $socket = new THttpClient('localhost', 8080, '/php/PhpServer.php');
  $socket = new TSocket('localhost', 9090);
  $transport = new TBufferedTransport($socket, 1024, 1024);
  $protocol = new TBinaryProtocol($transport);
  $client = new \tutorial\CalculatorClient($protocol);

  $transport->open();


} catch (TException $tx) {
  print 'TException: '.$tx->getMessage()."
";
}
