PHP ProcessManager for Request-Response Applications

Why forking?

This is a fork of marcj/php-pm.

What is different from the original repo, is that this PM is written specially for @RePHP framework, where asynchronous nature achieved based on PHP5.5 generators, and does not need any event libraries.

About

PHP-PM is a process manager for Request-Response Frameworks running in a @RePHP environment. The approach of this is to kill the expensive bootstrap of PHP (declaring symbols) and bootstrap of feature-rich frameworks.

More information about original PM porpouse can be found in the article: Bring High Performance Into Your PHP App (with ReactPHP)

Install

The recommended way to install react is through composer.

Command

./bin/ppm start --help
Usage:
 start [--bridge="..."] [--port[="..."]] [--workers[="..."]] [--bootstrap[="..."]] [--app-env[="..."]] [--memory-limit[="..."]] [--memory-check-time[="..."]] [working-directory]

Arguments:
 working-directory     The working directory.  (default: "./")

Options:
 --bridge              The bridge we use to convert a ReactPHP-Request to your target framework.
 --host                Load-Balancer host. Default is 127.0.0.1
 --port                Load-Balancer port. Default is 8080
 --workers             Worker count. Default is 8. Should be minimum equal to the number of CPU cores.
 --app-env             The that your application will use to bootstrap.
 --bootstrap           The class that will be used to bootstrap your application.
 --memory-limit        The memory limit for one slave process
 --memory-check-time   Time in seconds for checking memory limit
 --help (-h)           Display this help message.
 --quiet (-q)          Do not output any message.
 --verbose (-v|vv|vvv) Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug
 --version (-V)        Display this application version.
 --ansi                Force ANSI output.
 --no-ansi             Disable ANSI output.
 --no-interaction (-n) Do not ask any interactive question.

Example

$ ./bin/ppm start ~/my/path/to/symfony/ --bridge=HttpKernel

Or through placing ppm.json in root dir

{
	"bootstrap": "\\PHPPM\\Bootstraps\\Symfony",
	"bridge": "HttpKernel",
	"appenv": "dev",
	"workers": 8
}

Each worker starts its own HTTP Server which listens on port 5501, 5502, 5503 etc. Range is 5501 -> 5500+<workersCount>.

Setup 1. Use external Load-Balancer

Example config for NGiNX for 8 workers:

upstream backend  {
    server 127.0.0.1:5501;
    server 127.0.0.1:5502;
    server 127.0.0.1:5503;
    server 127.0.0.1:5504;
    server 127.0.0.1:5505;
    server 127.0.0.1:5506;
    server 127.0.0.1:5507;
    server 127.0.0.1:5508;
}

server {
    root /path/to/symfony/web/;
    server_name servername.com;

    location / {
                #index index.php;

                # try to serve file directly, fallback to rewrite
                try_files $uri @rewriteapp;
        }

        location @rewriteapp {
                if (!-f $request_filename) {
                        proxy_pass http://backend;
                        break;
                }
        }
}

Setup 2. Use internal Load-Balancer

This setup is slower as we can't load balance incoming connections as fast as NGiNX it does, but it's perfect for testing purposes.
