Web Database Applications with PHP and MySQL, 2nd Edition by Hugh E. Williams, David Lane

Most of the services we enjoy on the Web are provided by web database applications. Web-based email, online shopping, forums and bulletin boards, corporate web sites, and sports and news portals are all database-driven. To build a modern web site, you need to develop a database application. This book presents a highly popular, easy, low-cost way to bring together the Web and databases to build applications. We discuss MySQL in detail in this book. With a web server such as Apache we assume Apache in this book, although the software discussed here works with other web servers as well and MySQL, you have most of what you need to develop a web database application.

While we could simply focus on how to create web pages and websites, none of this is possible without the underlying hardware and software components that support the pages we create. Examining what these components are and how they interact helps us understand what our server is capable of. The diagram below represents the basic elements of a web server. Hardware, an operating system, and an http server comprise the bare necessities. The mention of phrases like data center, hosting provider, or even big name companies like Microsoft and Google can invoke mental images of large, sterile rooms full of tall racks of hardware with blinking lights and a maze of wires. Those more familiar with such rooms will also know the chill resulting from the heavily air conditioned atmosphere and droning whir of fans that typically accompany them. This, however, is not a requirement nor an accurate portrayal of a great deal of servers connected to the Internet.

Web server

A web server is a computer that runs websites. It's a computer program that distributes web pages as they are requisitioned. The basic objective of the web server is to store, process and deliver web pages to the users. These web pages are mostly static content that includes HTML documents, images, style sheets, test etc. A software for which the original source code is made freely available and may be redistributed and modified according to the requirement of the user.

The Web was originally conceived and developed to meet the demand for automated information-sharing between scientists in universities and institutes around the world. CERN is not an isolated laboratory, but rather the focal point for an extensive community that includes more than 17 scientists from over countries. Although they typically spend some time on the CERN site, the scientists usually work at universities and national laboratories in their home countries. Reliable communication tools are therefore essential. The basic idea of the WWW was to merge the evolving technologies of computers, data networks and hypertext into a powerful and easy to use global information system.

Now that you know the purpose and potential benefits of server-side programming we're going to examine in detail what happens when a server receives a "dynamic request" from a browser. As most website server-side code handles requests and responses in similar ways, this will help you understand what you need to do when writing most of your own code. There is no real code in the discussion because we haven't yet chosen a web framework to use to write our code! This discussion is however still very relevant, because the described behavior must be implemented by your server-side code, irrespective of which programming language or web framework you select. When you click a link on a web page, submit a form, or run a search, the browser sends an HTTP Request to the server. The body of a successful response to a GET request would contain the requested resource.

A server is a computer or system that provides resources, data, services, or programs to other computers, known as clients, over a network. In theory, whenever computers share resources with client machines they are considered servers. There are many types of servers, including web servers, mail servers, and virtual servers.

Web servers may soon be able to handle other types of transport protocols for HTTP requests.

Servers—Constantly running programs that serve up information to the Web. If your computer system is on a network, chances are that you are already main names, new IP addresses, and new domain-to-IP associations can be introduced in types such as quicktime, PDF, audio and video are handled by plug-ins or.

Web browsers use their own protocols (SMTP, HTTP, etc.) Web servers are full of features that allow them to do more than just browsers to display PDF (​Portable Document Format) files, and Macro- (introduced with.

For International Network communication, we require a web browser and web servers.
