Using a different Chrome executable

// Setting the binary is optional. 
$options->setBinary('/home/php-webdirver/chrome/my_chrome_binary');

Launch with Chrome extensions

// Setting extensions is also optional
$options->addExtensions(array(
  '/path/to/chrome/extension1.crx',
  '/path/to/chrome/extension2.crx',
));

Starting Chrome with the above configuration

$caps = DesiredCapabilities::chrome();
$caps->setCapability(ChromeOptions::CAPABILITY, $options);

$driver = RemoteWebDriver::create($url, $caps);
