PHP Introduction

PHP introduction

PHP is a powerful tool for creating interactive and dynamic web pages. To get skilled in PHP, you should have a basic understanding of HTML/XHTML and JavaScript.
PHP stands for Hypertext Preprocessor. This is a server-side scripting language (like ASP) which supports many databases (MySQL, Informix, Oracle, Sybase, Solid, PostgreSQL, Generic ODBC, etc.) As PHP is an open source software, it can be downloaded and used for free. PHP is easy to learn and runs efficiently on the server side. To get access to a web server with PHP support, you may install Apache (or IIS) on your own server, install PHP, and MySQL.
PHP file (".php", ".php3", or ".phtml" file extensions) is returned to the browser as plain HTML. It can contain text, HTML tags and scripts.
