安装selenium：
```
composer  require  facebook/webdriver
```
下载jdk（略）
下载selenium服务：
```
https://goo.gl/FCSwwD
```

运行selenium服务：

java  -jar  selenium-server-standalone-3.14.0.jar

下载chromedriver：

https://chromedriver.storage.googleapis.com/2.9/chromedriver_win32.zip

将chromedriver放到chrome安装目录下：

C:\Program Files (x86)\Google\Chrome\Application

移动chromedriver到chrome安装目录：
添加chrome安装目录下环境变量：

编写测试代码（test.php）：

<?php
namespace Facebook\WebDriver;
use Facebook\WebDriver\Remote\DesiredCapabilities;
use Facebook\WebDriver\Remote\RemoteWebDriver;
require_once('vendor/autoload.php');
header("Content-Type: text/html; charset=UTF-8");
$waitSeconds = 15;  //需等待加载的时间，一般加载时间在0-15秒，如果超过15秒，报错。
$host = 'http://localhost:4444/wd/hub'; // this is the default
$capabilities = DesiredCapabilities::chrome();
$driver = RemoteWebDriver::create($host, $capabilities, 5000);
$baseUrl = 'http://www.bilibili.com/';
$driver->get($baseUrl);
echo consoleText($driver->getTitle()) . "\n";    //cmd.exe中文乱码，所以需转码
$topLists = $driver->findElement(WebDriverBy::className('container-top-wrapper'))->findElement(WebDriverBy::className('top-list-wrapper'))->findElements(WebDriverBy::tagName('li'));
foreach ($topLists as $topLi) {
$itemContent = $topLi->findElement(WebDriverBy::tagName('a'));
echo consoleText($itemContent->getAttribute('title')) . ' : ' . consoleText($itemContent->getAttribute('href')) . "\n";
}
//关闭浏览器
$driver->quit();
function consoleText($text, $pageEncoding = '', $consoleEncoding = '')
{
// windows
if (!$consoleEncoding) {
    if (stristr(php_uname('s'), 'win')) {
        $consoleEncoding = "GBK";
    } else {
        $consoleEncoding = 'UTF-8';
    }
}
return exchangeEncoding($text, $pageEncoding, $consoleEncoding);
}
function exchangeEncoding($text, $pageEncoding = '', $targetEncoding = 'UTF-8')
{
if (!$pageEncoding) {
    $pageEncoding = mb_detect_encoding($text, array("ASCII", 'UTF-8', "GB2312", "GBK", 'BIG5'));
}

if ($pageEncoding != $targetEncoding) {
    return mb_convert_encoding($text,$targetEncoding,$pageEncoding);
}

return $text;
}
//切换至最后一个window
function switchToEndWindow($driver)
{

$arr = $driver->getWindowHandles();
foreach ($arr as $k => $v) {
    if ($k == (count($arr) - 1)) {
        $driver->switchTo()->window($v);
    }
}
}

运行测试代码：
```
php  test.php
```
