Javascript php code

Question

Is it possible to run some javascript expression? egecho eval("Math.sqrt('25')");

Answer 1

In normal situations:

• PHP runs on the server
• and then Javascript runs on the client in a browser.

So no, it's not entirely possible for PHP to execute some Javascript code on the server.

But at least there is a PHP extension that embeds (or wraps around) the Javascript engine and, as a result, allows you to run Javascript on the server, starting with PHP.

The extension I'm thinking of is spidermonkey : installing and enabling it on your server will allow you to execute Javascript code on a server with PHP.
