I am using Symfony Panther for web scraping (not testing) in a PHP project that does not use Symfony. I installed via Composer. Each time I need to scrape a link submitted by a user, I start a new Chrome Browser.

$client = Symfony\Component\Panther\Client::createChromeClient('/usr/bin/chromedriver');
$client->request('GET', $url);
$crawler = $client->waitFor('body');

Starting a new Chrome browser for each submitted $url is slow and resource intensive, so I want to keep the Chrome Client running on port 9515 and then each user's $url request can connect to that one same instance. Based on some user comments on Github, it sounds like a reasonable method:

  • Spin up a Chrome instance on the Linux server, running on port 9515
  • Make each url request connect to that instance.

I placed the first line i.e. with createChromeClient in a php script for a CRON job, but it never starts up the chrome client, and I get no errors either. Any ideas how to achieve this?

"Not showing" the browser (Chrome here) is the default way, as it is faster. It is called "headless"

To show it, you have to specify "PANTHER_NO_HEADLESS" :

PANTHER_NO_HEADLESS=1 vendor/bin/phpunit -c phpunit.xml

also, you could check if chome is running with : (or any system log)

ps aux | grep chrome

@Cogicero You set this option in phpunit.xml.dist file :

<env name="PANTHER_NO_HEADLESS" value="1" />

And comment it if u don't want to see the browser.
