PHP

A popular general-purpose scripting language, especially suited for web development. Fast, flexible, and pragmatic, PHP powers everything from your blog to the world's most popular websites. PHP, which stands for PHP: Hypertext Preprocessor, is a widely-used open-source general-purpose scripting language that is especially suited for web development and can be embedded into HTML. Its syntax draws inspiration from C, Java, and Perl, making it easy to learn. The primary goal of the language is to enable web developers to quickly write dynamically generated web pages, but you can do much more with PHP. Unlike pages that use extensive commands to output HTML (as seen in C or Perl), PHP pages contain HTML with embedded code that performs certain actions (in this case, outputting "Hi, I'm a PHP script!"). PHP code is enclosed within special start and end processing instructions, `<?PHP` and `?>`, allowing you to switch in and out of "PHP mode." The difference between PHP and client-side languages like JavaScript is that the code is executed on the server, generating HTML, which is then sent to the client. The client receives the result of running the script without knowing the underlying code. A web server can even be configured to process all HTML files with PHP, making it impossible for users to tell that PHP is being used. The greatest advantage of PHP is that it is incredibly simple for beginners, yet offers a wealth of advanced features for professional programmers. Don’t be intimidated by the long list of PHP capabilities. With PHP, almost anyone can get started quickly and write simple scripts. Although PHP development primarily focuses on server-side scripting, it is capable of much more.
