v8php - Embed PHP into v8.

This is a work-in-progress project, that will allow you to create and use a PHP instance from within nodejs, in order to enhance interaction with the two different worlds. The API will be designed to be async and modeled after child_process.spawn.

Features I want to implement

• Creating a new PHP instance, even simultanous ones. That means, that I need to find a precise way to connect one php worker thread to exactly one object - in reference.
• Using request contexts. I.e., pretending to be something like Apache.
• Preparing the "built-in" INI.
• Forwarding header information (request.headers).
• Creating an async API to allow non-blocking usage.

A possible API usage.

function my_handler(request, response) {
    var PHP = require("v8php").requestEngine,
        proc = PHP(__dirname+"/"+request.url, {
            max_script_execution: 100,
            // ... snip. More options, actually INI settings.
        });

    proc.on("header",function(string){ response.header(string); });
    proc.on("output",function(chunk){ response.write(chunk.toString("utf-8")); });
    proc.on("error",function(chunk){ console.error(chunk.toString("utf-8")); });
    proc.on("end",function(chunk){ request.end(); });
}

Needed

You need PHP configured with --enable-embed and --enable-maintainer-zts. We are actually using another abstraction, the embed2 SAPI, but this one is compiled in the process of this module, and linked inside. The module, unline others, is not built using node-gyp or phpize. We use build.js in order to do that. Its simple, but reqrueis information from both sides. You need node-gyp installed in order for the script to be able to pick up or download neccessary nodejs development files.

Possible object structure

PHP: {
    requestEngine: [Function], // Returns an event emitter that handles HTTP-ish requests.
    cliEngine: [Function], // Simpler interface, its like the php-cli SAPI.
    modules: [...], // Name:Version list of all available modules. Might do that, might not. Really, depends...
    version: "..."
}
