SERVER-SIDE PROGRAMMING

In many cases, client-side applications will be insufficient

Heavy processing

Communication with other clients

Data available on server-side only

It may be useful to send the request to the server, and toprocess it there.

A number of technologies available: CGI, Servlets, JSP,ASP, PHP and others

We will look at PHP, ASP and JSP.

Development started in 1994, by Rasmus Lerdorf.

A project of the Apache Software Foundation

http://www.php.net

Open Source, free server-side HTML-embedded scripting

language Cross-platform, suitable for today's heterogeneous network

environments

PHP's syntax resembles C and Perl and is easy to learn for anyprogrammer with C or Perl background

Simpler and faster to develop in (than C and Perl)

Personal Home Page (PHP)

PHP is mainly focused on server-side scripting, so youcan do anything any other CGI program can do, such

as collect form data, generate dynamic page content,

or send and receive cookies.

What is PHP?

PHP is a general-purpose server-side scripting language

originally designed for Web development to produce

dynamic Web pages. It is one of the first developed server-

side scripting languages to be embedded into an HTML

source document, rather than calling an external file toprocess data.

PHP vs. JSP

PHP is faster in execution time

A recent survey in ZDnet's eWeekonline publication found thatPHP is as much as 3.5 times faster than JSP

Faster in development time flatter learning curve

PHP supports any 32-bit or better platform, whereas JSPsupports only platforms that have a Java virtual machineavailable


10/13

PHP vs. ASP

PHP is faster

Superior Memory Management

Closer to C Style of Programming

Cross Platform Migration Strategy

Dynamic generation of UI is more flexible


11/13

Advantages of PHP

Light-weight

Cross-platform compatible

Procedural / Object Oriented programming

Supports wide range of Databases

Supports wide variety of outputs

Supports wide variety of protocols

Extremely useful text processing features

Open source
