Panther is a convenient standalone library to scrape websites and to run end-to-end tests using real browsers.
Panther is super powerful. It leverages the W3C's WebDriver protocol to drive native web browsers such as Google Chrome and Firefox.
Panther is very easy to use, because it implements Symfony's popular BrowserKit and DomCrawler APIs, and contains all the features you need to test your apps. It will sound familiar if you have ever created a functional test for a Symfony app: as the API is exactly the same! Keep in mind that Panther can be used in every PHP project, as it is a standalone library.
Panther automatically finds your local installation of Chrome or Firefox and launches them, so you don't need to install anything else on your computer, a Selenium server is not needed!
In test mode, Panther automatically starts your application using the PHP built-in web-server. You can focus on writing your tests or web-scraping scenario and Panther will take care of everything else.
Features:
- executes the JavaScript code contained in webpages
- supports everything that Chrome (or Firefox) implements
- allows taking screenshots
- can wait for asynchronously loaded elements to show up
- lets you run your own JS code or XPath queries in the context of the loaded page
- supports custom Selenium server installations
- supports remote browser testing services including SauceLabs and BrowserStack
Selenium Driverless is a Selenium inspired browser automation library with focus on web scraping detection bypass. It shares most of Selenium API and UX but implements several extensions that make the scraper more difficult to detect and extra usability features like: - Bypass Cloudflare - Multiple Tab scraping - Multiple context support - Proxy auth - Network interception
Example Use
<?php
use Symfony\Component\Panther\Client;
require __DIR__.'/vendor/autoload.php'; // Composer's autoloader
$client = Client::createChromeClient();
// Or, if you care about the open web and prefer to use Firefox
$client = Client::createFirefoxClient();
$client->request('GET', 'https://api-platform.com'); // Yes, this website is 100% written in JavaScript
$client->clickLink('Get started');
// Wait for an element to be present in the DOM (even if hidden)
$crawler = $client->waitFor('#installing-the-framework');
// Alternatively, wait for an element to be visible
$crawler = $client->waitForVisibility('#installing-the-framework');
echo $crawler->filter('#installing-the-framework')->text();
$client->takeScreenshot('screen.png'); // Yeah, screenshot!
# It works the same as Selenium just with a different import.
import undetected_chromedriver as uc
driver = uc.Chrome(headless=True, use_subprocess=False)
driver.get('https://nowsecure.nl')
driver.save_screenshot('screenshot.png')
driver.close()
