PHP Introduction

The PHP machine-readable text Preprocessor (PHP) may be a programing language that enables internet developers
to create dynamic content that interacts with databases.PHP may be a scripting language, like HTML. which means that code doesn’t ought to be compiled before it gets used — it gets processed on the fly as necessary.

In order to develop and run PHP Web pages three vital components need to be installed on your computer system.

    • Web Server − PHP will work with virtually all Web Server software, including Microsoft’s Internet Information Server (IIS) but then most often used is freely available Apache Server. Download Apache for free here − http://httpd.apache.org/download.cgi
    • Database − PHP will work with virtually all database software, including Oracle and Sybase but most commonly used is freely available MySQL database. Download MySQL for free here − http://www.mysql.com/downloads/
    • PHP Parser − In order to process PHP script instructions a parser must be installed to generate HTML output that can be sent to the Web Browser. This tutorial will guide you how to install PHP parser on your computer.
