Beginning PHP 5.3 by Matt Doyle
This means that you can develop and test your PHP Web site on one setup, then deploy it on a different type of system without having to change much of your code. How does PHP compare with other common Web programming technologies?
Because ASP. NET gives you a large library of code for doing things like creating HTML forms and accessing database tables, you can get a Web application up and running very quickly. NET does.
Many would argue that C is a nicer, better-organized language to program in than PHP, although C is arguably harder to learn. Another advantage of ASP. First of all, they have a commercial license, which can mean spending additional money on server software, and hosting is often more expensive as a result.
NET are fairly heavily tied to the Windows platform, whereas the other technologies in this list are much more cross-platform. The main downside of Java compared to PHP is that it has quite a steep learning curve, and you have to write a fair bit of code to get even a simple Web site going though JSP helps a lot in this regard. Overall, Python is a very nice language, but PHP is currently a lot more popular, and has a lot more built-in functionality to help with building Web sites.
An additional plus point is its tight integration with Flex, another Adobe technology that allows you to build complex Flash-based Web applications.
PHP and Apache are, of course, free and open source. In summary, PHP occupies something of a middle ground when it comes to Web programming languages. This makes PHP highly suited to its main job: building Web sites.
In the past, PHP has been criticized for the way it handled a number of things — for example, one of its main stumbling blocks was the way in which it implemented object support. However, since version 5, PHP has taken stock of the downfalls of its predecessors and, where necessary, has completely rewritten the way in which it implements its functionality.
Another important component is the HTML document type declaration , which triggers standards mode rendering.
The following is an example of the classic "Hello, World! If a declaration is not included, various browsers will revert to " quirks mode " for rendering. The text content of the element, if any, is placed between these tags. Tags may also enclose further tag markup between the start and end, including a mixture of tags and text.
This indicates further nested elements, as children of the parent element. The start tag may also include attributes within the tag.

These require only a single empty tag akin to a start tag and do not use an end tag.Checkbox field Nothing is sent at all.
