How to make a PHP and JS backend?

Question

I know that you can use PHP or node.js server-side, but is it possible to use both PHP and JS together, for example PHP calling a JS function?

My goal is to call JS for the more intensive math functions, but I don't want these to be seen on the clientside. I've tried searching many different sites but it seems my question is pretty specific. Thanks

Please read over stackoverflow.com/help/how-to-ask , and its very helpful to attempt stackoverflow.com/help/mcve — IncredibleHat

@Randall: What would an MCVE of this question even look like? The question is quite clear, if a bit broad: Is it possible to call JS server-side from PHP and, if so, how? — T.J. Crowder

I was about to answer this by recommending PHP V8js if you really want to do this. — blues

Related but not a dupetarget: stackoverflow.com/questions/18760984/mix-node-js-and-php (that question is specifically about generating a "page" in PHP then passing it through JavaScript code to amend the page; this question isn't limited in that way). — T.J. Crowder

@Randall: Many -- most -- questions are code-specific. Not all by any means. — T.J. Crowder

There are a couple of ways to do this:

Use some kind of bridging technology. The briefest search turned up this one, for instance. Edit: User blues mentions PHP V8js as well.
Have a Node process running and bound only to localhost, and have your PHP code make queries to it (perhaps via HTTP).

If node was installed on the same server, I guess you wouldn't necessarily need a node http server running. You could just exec node files, right?

@Don'tPanic: Fair point, absolutely. You'd have the cost of spinning up a process, though, which is fairly costly, as opposed to connecting to an existing process. But yes, quite true. :-)
