Hi,

define("Name", "Deepak");

echo Name;  // Outputs Deepak


define("Name", "Ravi");

echo Name;  // Outputs Deepak

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.
