UserAgent
How i may set "useragent" in php-phantomjs?
You can add it by setting the userAgent in your PhantomJS script:
page.settings.userAgent = 'YourUserAgent';
This is not currently supported in this library but will add it to the list for V4.
will add if you library simulate a click on a page element and receiving the resulting page?
If you want DOM navigation you're probably better to look into the Symfony DOM crawler library - http://symfony.com/doc/current/components/dom_crawler.html
It is supported in V4?
you havent added it to the docs. Now I cannot spoof it into thinking im running on chrome so that youtube videos load
