Google Analytics with AMP

I read here:

https://www.sitepoint.com/an-introduction-to-googles-accelerated-mobile-pages-amp/

That Google Analytics can track AMP pages.

Supposedly, this is the code:

<amp-pixel src="https://ssl.google-analytics.com/collect?v=1
                &tid=UA-12345678-1&t=pageview&cid=__CID__
                &dt=__PAGE_TITLE__&dl=__PAGE_URL__
                &z=__RANDOM_STRING__">
</amp-pixel>

But I don’t know what to put in the CID, PAGE_TITLE, PAGE_URL, and RANDOM_STRING sections.

Any php experts able to help with this?
