PH7 is an embeddable PHP engine written in C that allows hosting applications to compile and execute PHP scripts directly without the overhead of CGI or other process-based approaches. It implements most of PHP 5.3 and introduces extensions. PH7 is highly portable, runs as a library, and has a small footprint, making it suitable for embedded systems. This document provides an overview of PH7 and instructions for getting started with a simple example C program that uses PH7 to execute a PHP script directly within the parent process.
