PHP Language Basics

Constants

General Info: Computer Language Constants

A constant is just like a variable (it holds a value) but, unlike a variable, you cannot change the value of a constant.

PHP:   define

In PHP, you declare constants using the define keyword:

define("CONST_NAME", "Value");

Constants in PHP are case sensitive. A common standard in PHP is to use all-uppercase letters, with underscores to separate words within the name.

Syntax Example:
define('FULL_NAME', 'Mike Prestwood');
define("AGE", 25);
  
echo "Your name is " . FULL_NAME . ".";
echo "You are " . AGE . ".";

Built-In Constants

The PHP website has a list of built-in predefined constants.
