PHP

PHP allows you to preform numerous mathematical tasks. You can do anything from simple addition to complex geometry. You can also do things like round numbers, convert bases, or find the absolute value of numbers.

Three core reason for using PHP

• Usage
• Security
• Syntax

"PHP: Hypertext Preprocessor is a widely used, general-purpose scripting language that was originally designed for web development to produce dynamic web pages. For this purpose, PHP code is embedded into the HTML source document and interpreted by a web server with a PHP processor module, which generates the web page document. As a general-purpose programming language, PHP code is processed by an interpreter application in command-line mode performing desired operating system operations and producing program output on its standard output channel. It may also function as a graphical application. PHP is available as a processor for most modern web servers and as standalone interpreter on most operating systems and computing platforms."

Web HTML Colours

HTML colors are defined using a hexadecimal (hex) notation for the combination of Red, Green, and Blue color values (RGB).

The lowest value that can be given to one of the light sources is 0 (hex 00). The highest value is 255 (hex FF).

Hex values are written as 3 double digit numbers, starting with a # sign.
