define("CONSTANT", "Hello world.");
echo CONSTANT; // Outputs Hello world
define("CONSTANT", "New Value");
echo CONSTANT; // Outputs Hello world
Means once you declair the define a constant value that
will become every time it will not take new value or it
will not redeclair.if you want change in value then declair
the variables for that purpose.
