未定义属性：stdClass :: $ ELEMENT

Question

[我在youtube上找到了有关使用php在Windows中运行Selenium Webdriver的教程。我已经设置了xampp，安装了一些依赖项，以及诸如jar文件和geckodriver之类的其他依赖项。当我执行php代码时。我得到这个错误。

Notice: Undefined property: stdClass::$ELEMENT in C:\xampp\htdocs\sample1\phpwebdriver\WebElement.php on line 28

这是我的PHP代码：

require_once "phpwebdriver/WebDriver.php";

$webdriver = new WebDriver("localhost", "4444");
$webdriver->connect("firefox");                            
$webdriver->get("http://google.com");
$element = $webdriver->findElementBy(LocatorStrategy::name, "q");
if ($element) {
    $element->sendKeys(array("hello" ) );
    $element->submit();
}

?>

[请有人帮助，我已经为这个错误工作了2天。我不知道该怎么办。预先感谢，如果有人回答了，请多谢。

如果使用此WebDriver，应该没问题。

我认为您不能使用require_once = phpwebdriver/WebDriver，因为它应该像vendor/autoload.php中那样由this original example代替。
