PHP - Basic information

What is PHP?

PHP (Hypertext Preprocessor, which is a recursive acronym) is a widely-used general-purpose scripting language that is especially suited for Web development and can be embedded into HTML. So, PHP is an HTML-embedded (behind the scene so the user is not exposed to it) scripting language. Much of its syntax is borrowed from C, Java and Perl with a couple of unique PHP-specific features thrown in. The goal of the language is to allow web developers to write dynamically generated pages quickly. The current version of PHP is PHP 5.0. Another interesting fact to know about PHP is that the code is executed on the server as it focuses on server-side scripting, generating HTML which is then sent to the client.

As the scripting code runs behind the scene that is on the server-side. Then as the user visits the website, PHP webpage, web server processes the PHP code. It then sees which parts it needs to show to users (content and pictures) and hides the other stuff (file operations, math calculations, etc.) then it translates the PHP code into HTML and sends the webpage to the client browser window.
