Web5 de jun. de 2024 · PHP Constants with const. A construct in which define () is a function is a PHP const. In order to initialize constants, we need use the static name and value with a const statement where define () permits interpolation and function calling while declaring the constant. This constriction is always case sensitive, specified in this construct. WebHow to declare a constant in GDScript. To declare a constant, all you have to do is use the const keyword. In this case, you have a constant value called neverChanges, and it is assigned the value 100. Like a variable, you can also declare a constant as a typed value. Still, it is redundant since the value can never change.
