How to check whether Selenium Server is running

Question

I have bunch of phpunit tests, part of them using selenium, and i need to know wheteher selenium server is running or not (windows). Is there way to check it from php?

Answer 1

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.
