Web Design in a Nutshell, 3rd Edition

PHP

PHP is another scripting language that allows you to create dynamically generated web pages (similar to ASP). PHP is a project of the Apache Software Foundation , so it is open source and available for free. PHP works with a variety of web servers, but it is most commonly used with Apache.

PHP code, which is similar to Perl or ASP, can be embedded into the HTML document using special PHP tags. PHP’s advantage over CGI scripting is that it is very easy to include short bits of PHP code directly in a web page, to process form data or extract information from a database, for example.
