Is it not must to put double quotes for constant value declaration?

Question

b'coz question is given as<?phpdefine("AGE",28)?>is this correct???.....

Answer 1

When it's an integer, quotes are not necessary.

// These are acceptable:
define("AGE", 28);
define("AGE", "28");

However, quotes are needed for string values.

// This will throw an error:
define("AGE", Twenty Eight);

// This is acceptable:
define("AGE", "Twenty Eight");

Answer 2

Yes its correct you can now do as example: echo AGE; //note no $ variable sign
