Introduction to PHP
PHP, an acronym for Hypertext Preprocessor, is a widely-used open source general-purpose scripting language. It is an HTML embedded scripting language and is especially suited for web development. The basic syntax of PHP is similar to C, Java, and Perl, and is easy to learn. PHP is used for creating interactive and dynamic web pages quickly, but you can do much more with PHP.
A simple example
<html> <head> <title>First PHP example</title> </head> <body> <?php echo "This is a simple PHP script!"; ?> </body> </html>
In the above example we have written a HTML script with some embedded code to display some text. The PHP code is enclosed in special start (<?php) and end (?>) tags that allows to go in and out of PHP mode. The extension of a php file is ".php".
