PHP is a powerful cross platform server side scripting language. It is a full featured programming language capable of managing huge database driven online environments. Using PHP you can query databases, create dynamic images, create e-commerce websites, manage security for online transactions, read & write files on the server, talk to remote servers - the possibilities are endless. MySQL is a small, compact database server ideal for stand-alone and enterprise applications. The PHP-MySQL combination is also cross-platform.
Like Javascript, php employs a syntax similar to C, and provides strong support for pattern matching and database access. Extension for a communicating with other network resources, such as mail and directory servers, is also available
PHP is an open source product. As with other open source products, such as Linux operating system and Apache HTTP server, PHP is not a commercial product. It is, instead, the result of contributions from a community of interested developers. Freely contributing to,and supporting its code base. One important result of its open source nature is that PHP is now available on a large number of platforms. It is compatible with Windows NT as well as several UNIX operating systems, and with a number of HTTP servers such as Apache, Microsoft’s IIS, and Netscape Enterprise server.
Applications:
Open source has brought a lot more than Unux to the computing world. It has also given us Linux, PHP and MySQL. PHP and MySQL are the world's best combination for creating database-driven websites.
Ajax (also known as AJAX), shorthand
for "Asynchronous JavaScript and XML," is a web development
technique for creating interactive web applications. The intent
is to make web pages feel more responsive by exchanging small amounts
of data with the server behind the scenes, so that the entire web
page does not have to be reloaded each time the user requests a
change. This is intended to increase the web page's interactivity,
speed, and usability.
SALIENT FEATURES
XHTML (or HTML) and CSS, for marking up and
styling information.
The DOM accessed with a client-side scripting
language, especially ECMAScript implementations such as JavaScript
and JScript, to dynamically display and interact with the information
presented.
The XMLHttpRequest object is used to exchange
data asynchronously with the web server. In some Ajax frameworks
and in certain situations, an IFrame object is used instead
of the XMLHttpRequest object to exchange data with the web
server, and in other implementations, dynamically added <script> tags
may be used.
XML is sometimes used as the format
for transferring data between the server and client, although
any format will work, including preformatted HTML, plain
text, JSON and even EBML. These files may be created dynamically
by some form of server-side scripting.
Application
1)
standards-based
presentation using XHTML and CSS;
2)
dynamic display and interaction
using the Document Object Model;
3)
data interchange and manipulation
using XML and XSLT;
