Set expiration browser date for external file in htaccess

Question

I'd like to optimize my website for Google. I've load the external js file for analytics. Other files I made mod_expires in .htaccess but I don't know how to do with in this case.

Google tells me that:

Take advantage of browser caching

If you set an expiration date or a maximum age in the HTTP headers for static resources, the browser loads previously downloaded resources from the local disk instead of from the network.

Use browser caching for the following cacheable resources:

http://www.google-analytics.com/analytics.js (2 hours)

I really apprentice who will help me.

It's much harder to set it in htaccess without plugin, will you consider sending the header via php? — Wils, Mar 27 '18 at 08:41
That's ok but what should I do in php with the load of external files? — Craig, Mar 27 '18 at 08:44
so you want to cache the analytics.js to the client's browser? — Wils, Mar 27 '18 at 08:45
I'd like to set an expiration date for the static resourse analytics.js on google server — Craig, Mar 27 '18 at 08:52
I think you won't be able to set cache expire on google server. — Wils, Mar 27 '18 at 09:19

I edit with what I have now, unluckily with what you write me I still have the problem. I simply add your code above what I copy-pasted in the question (edited). – Craig Mar 27 '18 at 09:09

I found the answer:

PageSpeed Insights 99/100 because of Google Analytics - How can I cache GA?

Here is the solution:

<?php if (!isset($_SERVER['HTTP_USER_AGENT']) || stripos($_SERVER['HTTP_USER_AGENT'], 'Speed Insights') === false): ?>
// your analytics code here
<?php endif; ?>
