PPM - PHP Process Manager

PHP-PM is a process manager, supercharger and load balancer for PHP applications.

It's based on ReactPHP and works best with applications that use request-response frameworks like Symfony's HTTPKernel. The approach of this is to kill the expensive bootstrap of PHP (declaring symbols, loading/parsing files) and the bootstrap of feature-rich frameworks. See Performance section for a quick hint. PHP-PM basically spawns several PHP instances as worker bootstraping your application (eg. the whole Symfony Kernel) and hold it in the memory to be prepared for every incoming request: This is why PHP-PM makes your application so fast.

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

Features

• Performance boost of over 15x (compared to PHP-FPM, Symfony applications).
• Integrated load balancer.
• Hot-Code reload (when PHP files changes).
• Static file serving for easy development procedures.
• Support for HttpKernel (Symfony/Laravel), Drupal, Zend.

Installation

Global

$ git clone git@github.com:php-pm/php-pm.git
$ cd php-pm
$ composer install
$ ln -s `pwd`/bin/ppm /usr/local/bin/ppm
$ ppm --help

Per project

composer require php-pm/php-pm:^0.1.0
composer require php-pm/httpkernel-adapter:^0.1.0 #if you have httpkernel
./vendor/bin/ppm config #places a ppm.json in your directory
./vendor/bin/ppm start #reads ppm.json and starts the server like you want

Once configured (composer and ppm.json) you can start your app on your development machine or server instantly:

composer install
./vendor/bin/ppm start

When debug is enabled, PHP-PM detects file changes and restarts its worker automatically.

Adapter

HttpKernel for Symfony/Laravel - https://github.com/php-pm/php-pm-httpkernel

Drupal - https://github.com/php-pm/php-pm-drupal

Zend - https://github.com/php-pm/php-pm-zend

Command

ppm start ~/my/path/to/symfony/ #default is symfony with httpKernel

Example for Symfony's HTTPKernel

cd php-pm
composer require php-pm/httpkernel-adapter:dev-master
$ ./bin/ppm start ~/my/path/to/symfony/ --bridge=httpKernel --bootstrap=PHPPM\Bootstraps\Symfony

Each worker starts its own HTTP Server which listens on port 5501, 5502, 5503 etc. Range is 5501 -> 5500+<workersCount>. You can integrate those workers directly in a load balancer like NGINX or use http://127.0.0.1:8080 directly.

Setup 1. Use external Load-Balancer

Example config for NGiNX:

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 {
    root /path/to/symfony/web/;
    server_name servername.com;
    location / {
        try_files $uri @backend;
    }
    location @backend {
        proxy_pass http://backend;
    }
}

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.
