How to check whether Selenium Server is running
By default Selenium server accepts commands on localhost port 4444
So you could do this:
<?php$selenium_running = false;$fp = @fsockopen('localhost', 4444);if ($fp !== false) { $selenium_running = true; fclose($fp);}var_dump($selenium_running);I dont personally like using @, but fsockopen insists on throwing a PHP notice, when the connection fails. Having this warning in output or even in log file is just annoying.
