With growing interest in the development of low cost development solutions in a corporate environment, PHP is becoming more and more popular. However, the biggest problem for most SAP developers is the need for quick information to help them hit the ground running. This book provides readers with a comprehensive assessment of what is really needed to work with PHP, as well as how the SAP and PHP systems work together. After a short introduction to PHP and its capability characteristics, the SAPRFC extension module for PHP 4 and PHP 5 is explained in detail. Working with a sample application, you will learn how the two systems communicate with one another, and how best to use PHP for your own SAP-related development projects.
