The Web is no longer static; it's dynamic. As the information content of the Web grows, so does the need to make Web sites more dynamic. Think of an e-shop that has 1,000 products. The owner has to create 1,000 Web pages (one for each product), and whenever anything changes, the owner has to change all those pages. Ouch!!! Wouldn't it be easier to have only one page that created and served the content on the fly from the information about the products stored in a database, depending on the client request?
Nowadays sites have to change constantly and provide up-to-date news, information, stock prices, and customized pages. PHP and SQL are two ways to make your site dynamic.

AJAX WEB SCRIPTING APPLIED TO INTERACTIVE STEREOSCOPIC IMAGING
Creating the illusion of depth in images was first invented 1838 by Sir Charles Wheatstone. It is today still a great experience to
view high quality large format images with depth perception, exceptionally of virtual objects like reconstructions of the past or
building projects.
High quality presentation of computer graphics is provided by projection onto a transparent screen surface from behind. Image
separation can be easily performed by polarisation filters in front of the projection lenses. It is necessary that the beholders carry
polarized glasses. Interactive viewing in this context means, that the observer is able to select image pairs from the database, can
zoom in and out, select the display details and sets the zero parallax to an arbitrary position. The selection must be simultaneously
transferred to the second image of the stereoscopic pair.
While each data projector is driven by its own computer, a PDA (personal digital assistant) is recommended to receive the
instructions from the presenter or viewer. That network configuration requires amongst other software tools Bluetooth, to connect
the PDA to a local computer network, and ActiveSync, to hold a continuous connection between the PDA and the host computer.
Furthermore a Web server with PHP (hypertext pre processor) extension is running. Web browsers are acting as clients on both
computers and the PDA as well.
The challenge is now to write an application software that provides an interface on the PDA to set the adjustments and pushes the
image information to the graphic cards of the host and the slave computer. To minimize the effort in software development, open
source software components are largely applied to this system. We take advantages from Mozilla Firefox Web browser and Apache
Web server.

free ebook and tutorial - Smarty, the compiling PHP template engine
It is undoubtedly one of the most asked questions on the PHP mailing lists : how do I make my PHP scripts independent of the layout ? While PHP is billed as "HTML embedded scripting language", after writing a couple of projects that mixed PHP and HTML freely one comes up with the idea that separation of form and content is a Good Thing[TM]. Inaddition, in many companies the roles of layout designer and programmer are separate. Consequently, the search for a templating solution ensues.
In our company for example, the development of an application goes on as follows : After there quirements docs are done, the interface designer makes mockups of the interface and gives them to the programmer. The programmer implements business Logic in PHP and uses interface mockups to create skelet on templates. The project is then handed off to the HTML designer / webpage layout person who brings the templates up to their full glory. The project may go back and forth between programming /HTML a couple of times. Thus, its important to have good template support be cause programmers don’t want anything to do with HTML and don’t want HTML designers mucking around with PHP code. Designers need support for config files, dynamic blocks and other interface issues, but they don’t want to have to deal with intricacies of the PHP programming language

free ebook and tutorial-PHP Integration with object relational DBMS
The definition and properties of an API between Amos II and PHP are the main topic soft his report. Amos II (Active Mediator Object System)is an extensible functional multidatabase system[1]. Functional queries, expressed in AmosQL, can be executed by one database or over a federation of distributed databases. AmosQL is a query language similar to the OOparts of SQL-99. Further more Amos II can be set up as a stand alone main-memory object-relational DBMS.
Two kinds of interfaces are offered between Amos II and the programming languages C[5] or Java[6], the call in interface and the call out interface. To call Amos II from an application the call in interface can be used. Establishing connections, sending queries and dealing with result sets are tasks of this interface. Contrary the call out interface is able to call external functions from C or Java. Once known to Amos II, these external functions can be used in AmosQL queries. The call in and call out interfaces permit the development of wrappers. Wrappers are small program modules that can access external data, for example XML documents, relational databases, webforms, MIDI files and web browsers.

free ebook and tutorial - JavaScript Scripting Guide for QuickTime
JavaScript can interact with QuickTime invarious ways. You can use JavaScript in a browser to detect Whether QuickTime is installed, you can use JavaScript to create the tags used to embed QuickTime content in a webpage, and you can use JavaScript to query and control the QuickTime plug-indirectly. This document describes client-side scripting using JavaScript and QuickTime browser plug-ins. All QuickTime browser plug-ins expose the exact same interfaces to JavaScript, whether the plug-in Is an Active Xcontrol, a Cocoa plug-in, or a Netscape-styleplug-in, allowing the same script to operate identically for Internet Explorer, Safari, FireFox, Mozilla, and other browsers that support plug-in scripting. Browsers that support the W3CsDOM Level 3 specification can receive DOM events from QuickTime, allowing movie events to trigger JavaScript functions without having to set timers or poll QuickTime for status events

free ebook and tutorial - A Taxonomy of JavaScript Redirection Spam
Redirection spam presents a web page with false content to a crawler for indexing, but automatically redirects the browser to a different web page. Redirection is usually immediate (on page load) but may also be triggered by a timer or a harmless user event such as a mouse move. JavaScript redirection is the most notorious of redirection techniques and is hard to detect as many of the prevalent crawlers are script-agnostic. In this paper, we study common JavaScript redirection spam techniques on the web. Our findings indicate that obfuscation techniques are very prevalent among JavaScript redirection spam pages. These obfuscation techniques limit the effectiveness of static analysis and static feature based systems. Based on our findings, we recommend a robust counter measure using a light weight JavaScript parser and engine

JavaScript is a very widely used language, and evolving it presented many unique challenges as well as some opportunities. The emphasis is on the rationale, insights, and constraints that led to the features rather than trying to describe the complete language.
