What is Atom?
Atom, as it is used here, refers to an XML language that enables web publishers to aggregate the content of their Web sites to be available to a variety of users. With Atom, publishers can create a standard format for WEB feeds. This feed enables users to read the content of a Web site through a software called a feed reader. It also enables other Web developers to publish the contents of the feed on their respective web sites.
Atom is not the only one by one aggregation standard currently in use. RSS is another standard format (also used in XML) earlier than Atom. In fact, Atom is created to address some of the limitations of RSS.
As a result, the Atom specification contains a large amount of excess RSS benefits. Atom provides a way to define the format of the data provided-for example, HTML, XHTML, and so on-and RSS does not. Unlike RSS, Atom can support globalization by Xml:lang attribute. Furthermore, the Request for Comments (RFC) 3339,atom also accepts more advanced (and standard) data formatting, which is completely different from RSS RFC 822.
Why should PHP be used in conjunction with Atom?
PHP represents the Php:hypertext Processor (Hyper-text processor). It may be the only one by one abbreviations in English that still contain the original abbreviation after the expansion. The initial meaning of PHP is Personal home page (personal homepage).
PHP is a scripting language that can generate dynamic server-side content. It works in coordination with HTML, and PHP code is often embedded in standard HTML WEB pages to help implement dynamic content.
PHP can also collaborate well with database management system MySQL. Through the years of WEB development, both technologies are evolving and have been working together on countless occasions. Much of it is due to an undeniable rationale: both are free.
The questions at the beginning of this section can be answered in this way, and PHP provides developers with the flexibility to generate dynamic content in a form that is easy to read and develop. Dynamic content is retrieved from the MySQL database. The output page (feed) is written in PHP so that it can render XML output that conforms to the Atom specification.
Note that this article assumes that you are already familiar with the basics of MySQL and PHP. If not, refer to the introductory tutorials in the Resources section of this article.
Defining business Use cases: Fishing Reports
Your boss is in your office now. He is very appreciative of the way the company website (fishinhole.com) works. The site is currently promoting and selling a variety of fishing tackle to professional anglers. The site also provides a forum for fishing reports for these enthusiasts to share their fishing experience.
Your boss sits down in your office with a chair and complains that the company's website is still on the rise. He wants to use the page's Fishing report section to lure more professional anglers to the site. He wants you to make this part of the site a "one-stop shop" for a worldwide professional fishing report. This is critical for the success of the fishinhole.com site (as he says). Your boss took a sip of coffee and smiled, then walked out of your office without saying anything else.
You lean back on the chair and start thinking: What can make the Fishing Report forum more widely available? After a while, an idea flashed into your mind: aggregation! Rather than simply using the Fishing Report section for fishinhole.com users and customers, it is better to aggregate this forum so that people can read the outline of the fishing report with their feed readers. Other Web developers can also include this aggregate feed on their web pages. In any case, people can click on the report title of interest and be linked back to fishinhole.com, where they are then exposed to a chain of direct marketing of fishing gear. That's a good idea.
