Const keyword
- Constants are one type of variable which we can define for any class with keyword const.
- Value of these variables cannot be changed any how after assigning.
- Class constants are different than normal variables, as we do not need $ to declare the class constants.
- If we are inside the class then values of the constants can be get using self keyword, but accessing the value outside the class you have to use Scope Resolution Operator.
