fixed the issue. Will look into that further You could simply define your keys themselves as constants:
keys.php
code :
const KEY_USER_NAME = 'user_name';
const KEY_USER_AGE = 'user_age';
// ...
require $path_to_somewhere . '/keys.php';

class YourClass 
{
  const API_USER_NAME = KEY_USER_NAME;
  const API_USER_AGE = KEY_USER_AGE;

  // ...
}

To fix this issue In PHP a const must be a value, not an expression. So const FOO_CONST = 'foo' . 'bar'; won't work either.
You have to use define or a class member that gets initialized in the constructor instead of a const. Initializing a class member outside a class method with an expression does not work either.

this will help The Ruby constants are expected to preserve the same value, it's a recommendation, not a must:

hope this fix your issue A PHP constant is defined like this:
code :
$myVariable="what up";
define('myConstant',"$myVariable");
echo myConstant;

like below fixes the issue You use an explicit type annotation telling the typescript compiler that Color is an empty object (: {}). You just need to remove that and the compiler will infer the correct type of the variable.
code :
const Color = {
  RED: {
    CODE: "RCB",
    PRICE: 15.70
  },
  BLUE: {
    CODE: "BBC",
    PRICE: 18.70
  },
  GREEN: {
    CODE: "GTA",
    PRICE: 13.70
  },
};
let price  = Color.RED.PRICE;
console.log(price);
let red: typeof Color[keyof typeof Color]  = Color.RED;
type ColorMember = typeof Color[keyof typeof Color];
let red: ColorMember  = Color.RED;
Perl: what happens when we assign a constant value to a reference variable instead of address of a variable?

it fixes the issue This is the same as setting any other variable to 10, except that the access is indirect.
perl will autovivify an anonymous scalar variable and assign the reference to $var so that this action can be fulfilled. If you print out $var you will get something like SCALAR(0x3ecec4).
