PHP Technologies
| PHP is a widely-used general-purpose scripting language that is especially suited for Web development and can be embedded into HTML. |
| Up until recently, scripting on the internet was something which very few people even attempted, let alone mastered. Recently though, more and more people have been building their own websites and scripting languages have become more important. Because of this, scripting languages are becomming easier to learn and PHP is one of the easiest and most powerful yet |
| What is PHP? |
| PHP, which stands for “Hypertext Preprocessor”, is a server-side, HTML embedded scripting language used to create dynamic Web pages. Much of its syntax is borrowed from C, Java and Perl with some unique features thrown in. The goal of the language is to allow Web developers to write dynamically generated pages quickly. |
| You create pages with PHP and HTML. In an HTML page, PHP code is enclosed within special PHP tags. When a visitor opens the page, the server processes the PHP code and then sends the output (not the PHP code itself) to the visitor’s browser just as with ASP or ColdFusion. It means that, unlike JavaScript, you don’t have to worry that someone can steal your PHP script. Unlike ASP or ColdFusion, however, PHP is Open Source and cross-platform. PHP runs on Windows NT and many Unix versions, and it can be built as an Apache module and as a binary that can run as a CGI. When built as an Apache module, PHP is especially lightweight and speedy. Without any process creation overhead, it can return results quickly, but it doesn’t require the tuning of mod perl to keep your server’s memory image small. |
